Evaluation of the diagnostic techniques in the detection of hookworm infestation among school children in Ethiopia: Cross-sectional study design

BackgroundHookworm infestation is an important public health concern especially in regions with poor sanitation and limited resources. In healthcare institutions in Ethiopia, wet mount microscopy with low performance has been used as the sole diagnostic technique. Sensitive diagnostic methods are essential for the proper identification of hookworm infection in national strategies for hookworm prevention and management. Thus, the objective of the article was to evaluate the performance of diagnostic techniques in the detection of hookworm infestation among school children in the Gozamin district, Northwest Ethiopia. MethodsA cross-sectional study with 530 school children was conducted from February to April 2022 in Ethiopia. The study participants were selected by using systematic random sampling technique. Direct wet mount (DWM), Richie’s, Kato-Katz (KK), and spontaneous tube sedimentation (STS) diagnostic techniques were utilized to process the stool samples. The data were entered into the Epi-data version 4.2 and the data was analyzed using SPSS version 25.0. The sensitivity, specificity, predictive values and test efficiency of the test were calculated with respect to the Composite Reference Standard (CRS) as the reference method. The degree of agreement with the methods of diagnosis was assessed by the Kappa value. ResultsThe overall prevalence of hookworm was 34.9 %. The detection rate of STS, Richie’s, KK and DWM techniques in hookworm detection was 30.2 %, 27.0 %, 22.3 % and 15.1 %, respectively. The sensitivity and test efficiency of STS to detect hookworm were 86.5 % and 95.3 %, for Richie’s 77.3 % and 92.1 %, for KK 63.8 % and 87.4 %, for DWM method 43.2 % and 80.2 %, respectively. The agreement of STS, Richie’s, KK and DWM techniques with CRS were perfect (κ = 0.893), perfect (κ = 0.816), substantial (κ = 0.696) and moderate (κ = 0.498), respectively in detecting hookworm parasites. ConclusionThe prevalence of hookworm among school children was high. The STS method is superior to other methods for detecting hookworm infections. The Richie’s technique was more successful in detecting the hookworm parasite than the KK and DWM techniques. It is important to implement the STS technique in routine diagnostic methods and in endemic areas of hookworm infection because it cheaper, easy to perform, and identifies a wide range of parasitic species.

Soil-transmitted helminthes prevalence, intensity, and associated factors among school-aged children in the communities of west Guji Zone, South Ethiopia

BackgroundSoil-transmitted helminth (STH) infections are a major health problem among school-age children in developing countries. Prolonged exposure to STH can lead to reduced physical fitness, stunted growth, anemia, bowel obstruction, and cognitive impairments. ObjectiveTo determine the prevalence, intensity, and associated risk factors of soil-transmitted helminths among school-aged children in the west Guji Zone, South Ethiopia. MethodsA community-based cross-sectional study was conducted among 614 randomly selected school-aged children in selected districts of the West Guji zone from February to March 2023. A pre-tested questionnaire was used, and samples were examined by wet mount and Kato-Katz techniques. Data entry was analyzed using SPSS. Binary and multivariable logistic regression analyses were applied to identify potential associated factors. P-value<0.05 was declared as statistical significance. ResultsThe overall prevalence of STH was 32.7 % (95 % CI: 28.4%–35.8 %). Ascaris lumbricoides 95 (11.1 %) was the most common identified STH. Most school-age children, 74 %, were infected with a mild intensity of soil-transmitted helminths (STH). The mean egg count for Ascaris lumbricoides, Trichuris trichiura, and hookworms was 4465.4, 563.7, and 958.9, respectively. The study found significant associations with several factors, including washing hands with soap after using the toilet (AOR: 2.8, 95 % CI: 1.8–4.6), trimming fingernails (AOR: 4.6, 95%CI: 2.9–7.1), and the habit of wearing shoes (AOR: 2, 95%CI: 1.4–2.9) ConclusionSoil-transmitted helminths infection prevalence is high among school-aged children of the study areas. To prevent and control these infections, comprehensive health education should focus on the importance of hygienic practices, improved sanitation, and regular deworming programs for school-aged children.

Prevalence of Entamoeba gingivalis Among Patients Attending Dental Clinics in Wasit Province

Gingivitis and periodontitis are two inflammatory illnesses that are also considered infectious diseases in the context of periodontal disease diagnosis, periodontitis is a widespread oral illness that affects people all over the world .The current study used the wet mount technique with physiological saline and Giemsa stain to ascertain the incidence of Entamoeba gingivalis among 30 subjects (15 men and 15 females). (73%), E. gingivalis was prevalent overall (21 - 30) year olds had the highest frequency of E. gingivalis (54.55%). Infection was highly significant in female (59%) than male (41%). The conclusion that periodontal disease has a higher prevalence of E. gingivalis. The presence of E. gingivalis in the oral cavity is interpreted as an indication of inadequate dental hygiene, even though it is not often linked to pathogenesis. It is important to emphasise that patients' oral hygiene practices are not up to scratch. They employ mostly ineffective oral cavity hygiene products.

Prevalence and Risk Factors of Intestinal Parasitic Infections among Schoolchildren in Katsina Metropolis, Katsina State, Nigeria

Intestinal Parasitic Infections (IPIs) are significant causes of morbidity, particularly among school-aged children. This cross-sectional study was conducted to assess the prevalence and risk factors of intestinal parasitic infections among schoolchildren in Katsina Metropolis, Katsina State, Nigeria. A total of 420 schoolchildren from five randomly selected primary schools were enrolled for the study. Socio-demographic data were collected using structured questionnaires administered to both the children and their parents. Stool samples were analyzed using the Kato-Katz and direct wet-mount techniques to identify the presence of parasitic infections. The overall prevalence of intestinal parasitic infections was found to be 33.6%. The most prevalent parasite was Ascaris lumbricoides, detected in 28.0% of the children, and followed by Giardia lamblia (23.3%), Hookworm (22.8%), Entamoeba coli (19.5%), and Trichuris trichiura (6.6%). The prevalence was higher in males (37.1%) compared to females (30.1%). Children aged 6-9 years showed a significantly higher prevalence (38.0%) than those aged ≥10 years (30.0%) (P&lt;0.05). The key risk factors identified included family size, dietary habits, lack of toilet facilities, drinking water sources and the educational status of parents. The study indicates that STHs and intestinal protozoa infections remain prevalent among schoolchildren in Katsina Metropolis, posing a substantial public health challenge. Addressing this issue requires increased public awareness, improved sanitation in schools, and the implementation of school-based deworming programs.

Bacilli load in PTB- intestinal helminths co-infected and PTB non -infected patients at selected public health facilities in Jimma zone, Oromia, Ethiopia: comparative cross-sectional study

BackgroundTuberculosis (TB) and intestinal helminths are diseases that pose a dual burden on public health in low-income countries. Previous studies have shown that helminths can affect the shedding of bacteria or the bacterial load in the sputum of active TB patients. However, there is limited information on bacterial load in TB patients with helminth infections.ObjectiveThis study aimed to compare bacterial load in helminths-infected and non-infected pulmonary tuberculosis patients at selected public health facilities in Jimma zone, Oromia, Ethiopia.MethodsThe study was conducted in Jimma Zone, Oromia, Ethiopia. A facility-based comparative cross-sectional study was employed from August 01, 2020, to January 2021. A total of 124 (55 intestinal helminths-infected and 69 non-infected) newly diagnosed smear-positive pulmonary tuberculosis (PTB) patients were included in the study. A convenience sampling technique was employed to recruit study participants, and a semi-structured questionnaire was used to collect data regarding socio-demographic characteristics and possible risk factors for intestinal helminths co-infection. Stool examination was performed using both wet mount and Kato Katz technique. Additionally, weight and height measurements, sputum, and blood samples were taken to determine body mass index, bacilli load, and diabetic mellitus, respectively. Data were entered into Epi-Data software version 3.1 and analyzed using Statistical Packages for Social Sciences (SPSS) Version 25. A statistically significant difference was defined as a P-value of less than 0.05.ResultsIntestinal helminths reduced bacilli load 3 times more than intestinal helminths non-infected PTB (AOR = 3.44; 95% CI; 1.52, 7.79; P = 0.003) However, diabetes mellitus, HIV, drinking alcohol and cigarette smoking were not associated with bacilli load. The rate of co-infection TB with intestinal helminths was 44%. The three most prevalent parasites detected were Trichuris trichiura 29 (66%), hookworm 19 (43%), and Ascaris lumbricoides 11(25%)). Among co-infected patients about 36 (81.8%) had a single parasite infection, and 19 (43.2%) had multiple infections. A body mass index < 18.5 (AOR = 3.26; 95% CI; 1.25, 8.56;P = 0.016) and untrimmed fingernail status (AOR = 3.63; 95%CI;1.32,9.93;P = 0.012) were significantly associated with PTB- intestinal helminth –co-infection.ConclusionHelminth infection was associated with a lower bacilli load compared to helmenths non-infected PTB. The rate of co-infection TB with intestinal helminths was 44%. Trichuris trichiura was the most prevalent helminth. Untrimmed fingernail and a body mass index were associated with PTB-intestinal helminth co-infection.

A cross-sectional study on the prevalence and associated risk factors for intestinal parasitic infections among under-five aged children in Dabat primary hospital, north Gondar, Ethiopia.

Intestinal parasitic infections (IPIs) are the main public health problems in several developing countries, and under-five-aged children are the most vulnerable groups of the population. The current study aimed to determine the prevalence and associated risk factors of IPIs among under-five-aged children at Dabat primary hospital, northwest Ethiopia. A cross-sectional hospital-based study including 384 under-five-aged children was conducted from February to June 2022. A structured questionnaire was used to collect relevant information on risk factors, and stool samples were collected and examined using wet mount and sedimentation techniques to determine prevalence. Chi-square and logistic regression were used to evaluate the possible association and the strength of the association between dependent and independent variables. The overall prevalence of intestinal parasites was 32.81%. Ten species of intestinal parasites were identified. Entamoeba histolytica / dispar was the predominant intestinal parasite species, with a prevalence of 7.55%. Giardia lamblia and hookworm had prevalence of 6.77% and 5.47% respectively. Those children whose Mother/guardian do not wash their hand before feeding their child are more than five time infected than those who do wash (AOR = 5.26, CI = 2.28-12.2, p < 0.001). Children who do not wear shoe are more infected than who did (AOR = 14.5, CI = 5.77-36.5, p < 0.001). Several risk factors were identified in this study among these washing hands after toilet before touching child, washing hands before feeding their child, Child meal and habit of shoes wearing were the main predictors of IPI. Since the prevalence of IPI observed in this study is that of under-five-aged children; raising awareness of mothers/guardians about how to keep hygiene; transmission ways and health impacts of IPIs; and proper way of feeding their children to avoid risk is crucial.

Prevalence and Risk Factors of Giardia intestinalis Infestation and Assemblage of Isolates Among Monastery Primary School Children in Yangon, Myanmar.

Giardiasisis one of the major causes of diarrhea among children. To determine the prevalence, risk factors, and genotype of Giardia intestinalis, a cross-sectional descriptive study was done on stool samples of 462 children attending three monastery primary schools from North Okkalapa Township in Yangon, Myanmar from January 2016 to February 2019. Socioeconomic data were collected using a pre-tested questionnaire after obtaining informed consent. Direct wet mount, formalin-ether sedimentation, and trichrome staining techniques were used for the primary identification and then molecular identification was carried out by conventional polymerase chain reaction(PCR)-sequencing assay. G. intestinalis was identified in 11.7% (54/462) of students. There was no significant association with water source (p=0.948) and drinking untreated water (p=0.595). The infection was more common in children with low-educated parents, unsanitary garbage disposal practices, and no restrooms. All isolates were G. intestinalis assemblage B. This is the first study characterizing human isolates in a lower region of Myanmar, at the molecular level [MOU1]. These findings pointed out the high prevalence of G. intestinalis among primary school children from densely populated and low-resource settings.

Burden and factors influencing intestinal parasitic infections among food handlers in Gondar City, Northwest Ethiopia.

Intestinal parasitic infections pose significant global health challenges, particularly in developing countries. Asymptomatic infections often present a considerable burden with food handlers serving as potential carriers. In Ethiopia, the prevalence of these parasites varies across regions, and accurate data in the study area is lacking. Therefore, this study aimed to investigate the prevalence of intestinal parasites among food handlers working in hotels and restaurants in Gondar City, Northwest Ethiopia. A cross-sectional study collected stool samples from food handlers alongside a structured questionnaire gathering socio-demographic and hygiene practice information. Stool specimens were screened for intestinal parasites using direct wet mount and formol-ether concentration techniques. The collected data were checked for completeness, entered into EpiData software version 3.1, and exported to SPSS version 20 for analysis. A multivariable logistic regression analysis was deemed statistically significant if the p-value was less than 0.05. A total of 257 food handlers working in hotels and restaurants in Gondar City participated in the study. Of these, 33.5% (86/257) were found positive for one or more intestinal parasites, with a 95% confidence interval (CI) of 28.0-39.5%. The study identified nine types of intestinal parasites, with E. histolytica/dispar (8.2%, 21/257) and Ascaris lumbricoides (6.6%, 17/257) being the predominant parasites, followed by hookworm (3.5%, 9/257) and S. mansoni (2.3%, 6/257). The prevalence of mixed infections was 9.3% (24/257). A significant association was observed between intestinal parasitic infection and the educational level of food handlers. In this study, a high prevalence of intestinal parasites was detected indicating poor hygiene practices of the food handlers at the study site. Even the prevalence of mixed infections was high. Regular training, strict adherence to personal hygiene and food-handling practices, and routine inspections and medical checkups for food handlers are crucial.

Assessment of the selected hematological profiles among malaria and Schistosoma mansoni co-infected patients, Northwest Ethiopia.

Malaria and schistosomiasis are infectious diseases that cause hematological profiles abnormalities. Malaria and Schistosoma mansoni co-infection causes exacerbation of health consequences and co-morbidities. The aim of this study was to assess the selected hematological profiles among malaria and S. mansoni co-infected patients at Dembiya Selected Health Institutions. An institutional-based comparative cross-sectional study was conducted from March 30 to August 10, 2022. A total of 140 individuals were enrolled in the study using a convenient sampling technique. Wet mount and Kato Katz technique were conducted to detect S. mansoni in Stool sample. Blood films were prepared for the detection of plasmodium. The data was coded and entered into EpiData version 3.1 before being analyzed with SPSS version 25. A P-value of less than 0.05 was considered statistically significant. Mean of WBC, neutrophil, lymphocyte, eosinophil, RBC, hemoglobin, and hematocrit [4.IU/L,2.2IU/L, 1.4IU/L, 0.1IU/L, 3.13IU/L, 9.5g/dL, and 28.7%, resepectively] in co-infected were significantly lower than [7.5IU/L, 4.6IU/L, 2.1IU/L, 0.38IU/L, 4.8IU/L, 14.6g/dL, and 43.7%, resepectively] in the healthy control participants. Mean of RBC, hemoglobin, and hematocrit [3.13IU/L, 9.5g/dL, 28.7%, resepectively] in co-infected were significantly lower compared to [3.8IU/L, 11.5g/dL, 33.9%, resepectively] in the malaria monoinfected participants and [3.7IU/L,11.5g/dL, 33.6%, resepectively] in the S. mansoni monoinfected participants. The result of hematological profiles in healthy participants had no significant difference compared to light,moderate and heavy S. mansoni infection intensity in coinfection. The number of S. mansoni eggs per gram of stool had been negatively correlated with hematological profiles of co-infected participants except lymphocyte and monocyte which correlated positively. Hematological profiles status in coinfection were significantly altered compared to malaria monoinfection, S. mansoni monoinfection, and healthy participants.Therefore, hematological tests should be used to monitor and manage coinfection related complications, and to reduce coinfection associated morbidity and mortality.

Prevalence of Salmonella spp., Shigella spp., and intestinal parasites among food handlers working in University of Gondar student's cafeteria, Northwest Ethiopia.

Food-borne infections continue to be a major public health problem at the international level. The issue becomes more serious in developing countries like Ethiopia. This study aimed to examine the prevalence of Salmonella and Shigella species and intestinal parasites, as well as antimicrobial resistance patterns and associated factors among food handlers at the University of Gondar cafeteria in northwest Ethiopia. An institutional-based cross-sectional study was conducted from February to June 2021 in the University of Gondar cafeterias. Data related to the socio-demographic characteristics and hygienic practices of study participants were collected using structured questionnaires. A total of 290 stool samples were collected from food handlers. Culture and conventional biochemical tests were used to isolate the Salmonella and the Shigella species. Wet mount, Formol-ether concentration, and Kato Katz techniques were applied to identify intestinal parasites. Additionally, drug susceptibility tests were performed using the disk diffusion method. Statistical analysis was done using SPSS version 26. Of 290 food handlers' stool samples analyzed, Twenty-seven 27 (9.3%) were positive for both Salmonella and Shigella species. The prevalence of Salmonella and Shigella species was 16 (5.5%) and 11 (3.8%), respectively. Most of the isolated pathogens were resistant to tetracycline 19 (70.4%), and trimethoprim/sulphamethoxazole 19 (70.4%). The overall rate of multi-drug resistant Shigella and Salmonella isolate was 59.3%. Besides, Fifty-seven 57 (19.7%) of the participants were positive for one or more intestinal parasites. The most prevalent intestinal Parasitosis was E. histolytica/dispar 22 (7.6%), followed by G. lamblia 13 (4.5%), and Ascaris lumbricoides 11 (3.8) not washing hands after using the toilet (AOR: 4.42, 95% CI: 1.57, 10.56), and consuming unpasteurized milk (AOR: 3.14, 95% CI: 1.65, 3.96), were factors significantly associated with the prevalence of Salmonella, and Shigella infection. Similarly, not washing hands after using the toilet (AOR: 2.19, 95% CI: 1.0, 1.4), and consuming unpasteurized milk (AOR: 10.4, 95% CI: 3.8, 28.8), were factors significantly associated with the prevalence of intestinal parasites infection. The prevalence of intestinal parasites, Salmonella, and Shigella species was high. Therefore, it is imperative to implement a public health policy that includes ongoing microbiological surveillance.

Status of selected biochemical and coagulation profiles and platelet count in malaria and malaria-Schistosoma mansoni co-infection among patients attending at Dembiya selected Health Institutions, Northwest Ethiopia

Malaria and schistosomiasis are infectious diseases that cause coagulation disorders, biochemical abnormalities, and thrombocytopenia. Malaria and Schistosoma mansoni co-infection cause exacerbations of health consequences and co-morbidities.This study aimed to compare the effect of malaria and Schistosoma mansoni co-infection and malaria infection on selected biochemical and coagulation profiles, and platelet count. An institutional-based comparative cross-sectional study was conducted from March 30 to August 10, 2022. A total of 70 individuals were enrolled in the study using a convenient sampling technique. Wet mount and Kato Katz techniques were conducted to detect Schistosoma mansoni in a stool sample. Blood films were prepared for the detection of plasmodium. The data was coded and entered into EpiData version 3.1 before being analyzed with SPSS version 25. An independent t test was used during data analysis. A P-value of less than 0.05 was considered statistically significant. The mean [SD] of alanine aminotransferase, aspartate aminotransferase, creatinine, total bilirubin, and direct bilirubin in the co-infected was higher than in malaria infected participants. However, the mean of total protein and glucose in co-infected was lower than in the malaria infected participants. The mean of prothrombin time, international normalization ratio, and activated partial thromboplastin time in co-infected was significantly higher, while the platelet count was lower compared to malaria infected participants. Biochemical and coagulation profiles, and platelet count status in co-infection were changed compared to malaria infected participants. Therefore, biochemical and coagulation profiles and platelet count tests should be used to monitor and manage co-infection related complications and to reduce co-infection associated morbidity and mortality.

Prevalence of hospital acquired gastrointestinal protozoa parasites among in-patients of a missionary and private hospital in Awka, Southeastern Nigeria

Regardless of the efforts by health organizations and hospital personnel, research continues to report hospital acquired infections in admitted patients worldwide. This research was carried out to survey the prevalence of hospital acquired gastrointestinal protozoa parasites among admitted patients of Regina Caeli Specialist Hospital (missionary hospital) and Izunna Hospital and Maternity (private hospital) in Awka South LGA of Anambra State, Southeast Nigeria. Two samples each from 79 patients were collected and analyzed using direct wet mount and formol ether concentration technique. Other information concerning demography and risk factors were obtained with the aid of a structured questionnaire. Data obtained was analyzed using chi-square test and probability values ≤ 0.05 were considered significant. Out of the samples examined, 9(11.4%) were positive for hospital acquired gastrointestinal protozoa parasites. Hospital acquired gastrointestinal protozoa parasites were found to occur in all two hospitals with the missionary hospital having the highest occurrence rate of 66.7%. Males recorded the highest prevalence of 6(15.8%) compared to females 3(7.3%) while age group 50-59years had the highest prevalence of 28.6%. Patients from the male ward recorded a higher prevalence of 17.9%. Meanwhile patients whose occupation is farming had a higher prevalence of 25.0% while patients who only wash their vegetables/fruits sometimes before eating presented a higher prevalence of 18.2%. Prevalence of hospital acquired gastrointestinal protozoa parasite infection was strongly associated with duration of hospital stay (P˂ 0.000). Out of the four parasites identified, Entamoeba histolytica was the most prevalent with 5(55.6%). Consequently, regulation of patients’ hospital stay, sanitation and better hygiene practices should be adopted and encouraged to prevent the spread of hospital acquired infection.

Intestinal Helminth Infections and Their Association with QuantiFERON-TB Gold Plus Test Performance in an Endemic Setting, Northwest Ethiopia.

Timely detection and treatment of latent TB infection (LTBI) is part of WHO's strategy against tuberculosis (TB). Helminth infections can modulate immune responses, potentially impacting the performance of interferon-gamma release assays (IGRAs) such as the QuantiFERON-TB Gold Plus (QFT-Plus). This study evaluated the association between helminth infections and QFT-Plus results among participants from a TB-endemic region. A cross-sectional study was conducted from October 2022 to March 2023 in Bahir Dar, Ethiopia. Stool samples of 314 potential participants were examined for helminths using wet mount and Kato-Katz techniques. LTBI was assessed by QFT-Plus from a total of 100 gender-matched helminth-positive and -negative participants. The association between helminth infection status, egg count, and QFT-Plus positivity was analyzed, and p values <0.05 were considered significant. Overall, 53 of 314 screened participants were infected with helminths (16.9%), with A. lumbricoides (47.2%) and hookworm (30.2%) as most prevalent species. The overall QFT-Plus positivity rate was 30.0%, with similar rates observed between helminth-positive and helminth-negative participants. Although QFT-Plus positivity was slightly lower in hookworm carriers (25%) compared to those with A. lumbricoides (32%), a higher-than-median hookworm egg burden was significantly associated with reduced QFT-Plus positivity (P = 0.029). QFT-Plus positivity was significantly higher among male participants than females (P = 0.032). While overall helminth infection status did not significantly affect QFT-Plus positivity, higher hookworm burden was associated with reduced QFT-Plus reactivity. These findings suggest that the type of helminth and infection intensity, rather than its mere presence, may influence IGRA performance. Further studies with larger sample sizes are warranted to understand the species-specific effect of helminth infection on immune modulation of the host.

Diversity of aquatic parasites in pristine spring waters in Tehsil Babuzai, Swat, Pakistan.

Global access to clean and safe drinking water remains a formidable challenge, contributing to a myriad of health issues. This research exposes the existence of waterborne parasites in seemingly pristine spring waters, indicating potential contamination. Daily extensive sampling of Seventeen water sources was conducted in the untarnished freshwater streams of Tehsil Babuzai, District Swat, Khyber Pakhtunkhwa, Pakistan, from February to September 2021. Employing a stringent filtration process, the collected samples were effectively concentrated to detect any waterborne parasites. Subsequent application of the wet mount technique, combined with the capabilities of a compound microscope, revealed a disconcerting reality: all examined samples tested positive for various parasites. Identified parasites included Schistosoma species, Ascaris lumbricoides, Trichiuria trichiuria, Taenia saginata, Entamoeba histolytica, Amoeba, Lacrymana olor, Tintinnids, Paramecium, Dileptus, Euglena, Loxodes striatus, Acanthocyclops lynceus, Spondylosium, Oscillatoria, Cyanobacteria, Cilindros, Cilindros cerro, Commensal amoeba mature cysts,, Filliform larva of Strongyloides, Cercaria larva, Larva of Taenia solium, Egg of Enterobius vermiculais, Egg of Isospora belli, Egg of Tapeworm, Egg of Schistosoma species, Egg of Toxocara, and Egg of Diphyllobothrium latum. These findings clearly demonstrate the presence of a diverse array of parasites in the freshwater springs of Tehsil Babuzai, Swat, Pakistan. Implementing robust water treatment protocols, conducting regular monitoring and testing, and raising awareness about the risks of waterborne parasites are crucial steps to safeguard public health in the region.

Prevalence of intestinal parasites and associated risk factors among primary school children in Uyo Akwa Ibom State, Nigeria

Intestinal parasitic infections have become a global public health, and this burden is even higher among children in primary schools. Therefore, the study aims to determine the prevalence and associated risk factors of intestinal parasitic infection among primary school children in both public and private schools in Uyo urban was investigated. A cross sectional parasitological study consisting of 2000 school children 1000 each from five private and five public primary schools was carried out in Uyo metropolis. Structured questionnaire was used to obtained data on associated risk factors of intestinal parasitic infection. Microscopic examination of stool specimen of children by wet mount and formol either concentration technique was used for parasitological analysis of faecal samples. The results implicate poor toilet facilities, contamination of sources of drinking water, poor environmental sanitation and children attitude of playing bare footed and poor personal hygiene as the major risks factors. The overall prevalence of 952 (47.6%) was recorded with 342 (34.2%) from private school and prevalence of 610 (61.0%) from public school out of 1000 pupil examined from each group of schools. The most dominance parasites were Ascaris lumbricoides (10.5%) Guardia intestinalis (8.9%) Ancyclostoma duodenales (8.9%) Entamoeba histolystica (10.5%) Trichuris trichuira (10.9), E coli (3.0%) Enterobius vermicularis (2.4%) and Strongyloides stercoralis (2.1%). There was corresponding decrease in infection rate as the age increase. There is an urgent need for government and school authorities to create and maintain better sanitary and toilet facilities in school.

Intestinal parasitic infections and their potential risk factors among prison inmates in Valencia, Spain

BackgroundDespite the fact that prison inmates are a population at higher risk than other groups of suffering from intestinal parasite infections in relation to their living conditions, information about these diseases in prison environments is still scarce. Herein, we analyze the status of intestinal parasite infections in a Spanish prison.MethodsA cross-sectional study involving 528 inmates was conducted from April to June 2022 among inmates at Centro Penitenciario Picassent (Valencia, Spain). Stool specimens were examined using the direct wet mount technique, the formol-ether concentration technique, and the Ziehl-Neelsen staining method. We used STATA 16.1 for data analysis. We consider a p-value less than 0.05 significant at a 95% confidence level.ResultsOf the 528 inmates (471 men and 57 women; a mean age of 41.94 years) enrolled in the study, 83 (15.7%) were infected. Only six species of protozoa were detected. The gut potential microeukaryotic pathobiont Blastocystis sp. was the predominant parasite, accounting for 37 (44.6%) of the infections. Gut parasite amebas (6.6%) and pathobionts (5.3%) were more prevalent than flagellates (2.3%). The prevalence of infection with pathogenic species (8.9%) was similar to that of non-pathogenic species (8.7%). Infection among men (15.2%) was higher than in women (0.6%) (p < 0.0001). In multivariate analysis, the country of birth (AOR = 0.31, 95% CI = 0.18–0.52) and the time spent in prison (AOR = 1.83, 95% CI = 1.06–3.14) were statistically significant associated to intestinal parasite infections (p < 0.0001 and p = 0.028, respectively).ConclusionThis study found low levels of intestinal parasite infections in the CPP which could be indicative of the implementation of sanitary measures in prison environments in Spain. The less time spent in prison favor the risk of having infection while the Spanish nationality of inmates could reduce the risk of infection. The main recommendation would be to introduce routine parasitological tests upon foreigners entering prison.

Diagnostic Performance of Toluidine Blue Stain for Direct Wet Mount Detection of Cryptosporidium Oocysts: Qualitative and Quantitative Comparison to the Modified Ziehl-Neelsen Stain.

(1) Background: The wet mount staining technique is a simple, economical, and rapid method for detecting parasitic stages. The objective of the current study was to evaluate wet mount diagnostic stains for Cryptosporidium infection in human faecal samples and to compare the sensitivity and qualitative performance of toluidine blue (TolB) and modified Ziehl-Neelsen (mZN) stain. (2) Methods: The collection, purification, and molecular amplification of Cryptosporidium oocysts were performed. TolB, malachite green, trypan blue, and crystal violet were evaluated qualitatively to diagnose Cryptosporidium oocysts. The outperforming stain was compared to mZN using a quantitative evaluation and qualitative scoring system. (3) Results: The oocysts of Cryptosporidium parvum were effectively purified and utilized for spiking. TolB was the most effective diagnostic stain among wet mount stains for detecting Cryptosporidium oocysts. TolB outperformed mZN in terms of sensitivity, with 100% versus 79% at a concentration of 104 and 49% versus 23% at a concentration of 102. TolB had the most favourable qualitative stain characteristics against mZN; however, sample freshness and being a temporary stain were crucial considerations. (4) Conclusions: This study emphasizes that TolB, as a routine wet mount technique for screening Cryptosporidium infection, will provide a more sensitive and faster method than mZN staining.

Knowledge, Attitudes and Practices Among Adult Malaria Patients Co-Infected with Opportunistic Intestinal Coccidian Parasites in Fundong Health District, Northwest, Cameroon: A Cross Section Study Design

Introduction: Malaria and intestinal coccidian parasitic co-infections, are becoming a public health emergency affecting millions of people around the world. They are among the leading cause of socio-economic problems, long suffering and death especially in developing countries like Cameroon. Introducing new appropriate preventive and control measures to the population requires thorough assessment of community and patient-based knowledge, attitude and preventive practices towards malaria and pathogenic intestinal coccidian parasites is crucial. Our study aimed to describe knowledge, attitudes, and practices and the risk factors among adult malaria patients co-infected with intestinal parasitic infections in the Fundong Health District, a locality in the Northwest Region of Cameroon. Methods: This was a cross-sectional study carried out between February and December, 2022 involving sixteen (16) health facilities in Fundong Health district. A total number of 330 patients participated in the study. Normal saline wet mount and formol-ether concentration techniques were employed in coccidian parasitic detection. Blood samples were subjected to Giemsa stained and viewed microscopically to detect the Plasmodium parasites. Pretested structured questionnaires were administered to collect information on patient’s socio-demographic factors and determine patients’ knowledge, attitudes and practices towards malaria and intestinal coccidian parasites, as well as their prevention and control. The Pearson’s Chi-Square (χ2) and Student T-test were performed a part of the statistical analysis to check for associations between malaria, infection and between malaria-coccidian co-infection and demographic factors. Statistical significance was set a P-value&lt;0.05. Results: Participants main sources of information on malaria were: Television (TV) and radio 111/330 (34%), community health workers 109/330 (33%), and Hospitals (37%). Participants had good knowledge of mosquito bite as the malaria transmission route, 296/330 (90%), night time is the frequent biting time for the mosquito 296/330(90%), dark corners 229 (69%) and dirty areas 175(53%) as mosquito resting places. Knowledge score was also good on cleaning of the house surroundings, 281/330(85%), clearing the bushes 180/330(55%), poor knowledge score on drainage of stagnant water113/330 (34%) as ways to prevent the mosquito from multiplying. Participants had good knowledge of insecticide treated bed nets 295/330 (89%) as the best way to prevent mosquito bites. However, participants also expressed poor knowledge on edges of the river or streams 7(20%), and animal shed 20/330 (6%) as mosquito hiding places, and Plasmodium specie as malaria causative agent 8/330 (2%) (P-value=0.011). Poor scores were recorded on knowledge of opportunistic intestinal coccidian parasites (19.4%) (P=0.427), and was significantly low on unsafe water (47.2%) (P-value=0.036) as possible transmission routes for coccidian parasites. The knowledge score was also low on the at-risk population for malaria and intestinal coccidian infection (31.9%) P-value=0.009. Participants who had poor knowledge about coccidian transmission routes were less likely to drink from protected water source with an odds of 0.713(95% CI: 0.297-1.711) P value=0.449, compared to those who were more knowledgeable and who were 2.981(95% CI: 1.367-6.115) P value=0.005, more likely to use protected source of drinking water. Participants who had hand washing facility in the household were 3.488 (1.760-6.912) value=0.001 times more likely have better knowledge of coccidian transmission routes compared to those who did not have 0.748 (95% CI: 0.406-1.376) P value=0.350. Poor knowledge score of poor hygiene as major cause of coccidian infection significantly associated with poor practice score of sometime or not at all disinfecting animal shed to prevent coccidian infection among study participants (P =0.039). Conclusion: The overall knowledge scores, attitude and practices level of participants towards malaria and opportunistic intestinal coccidian parasites were relatively good. A significant proportion of the participants still have misconceptions about cause, modes of transmission and practices towards malaria and coccidian prevention methods. A combined health education programmes for malaria and intestinal coccidian parasites aimed at raising community awareness needs to be evidence based and requires innovative approaches, to address the gaps identified in the study.

Postpartum anemia and its determinant factors among postnatal women in two selected health institutes in Gondar, Northwest Ethiopia: A facility-based, cross-sectional study.

Anemia is highly prevalent globally and disproportionately affects postnatal women. It is a significant cause of maternal mortality and morbidity globally. The main aim of this study was to determine the extent of postpartum anemia and associated factors among postnatal women in two selected health facilities in Gondar, Northwest Ethiopia. A facility-based, cross-sectional study was conducted among 282 postnatal women from March to May 2021. A systematic sampling technique was used to recruit study participants from each institute. Sociodemographic, obstetric, and clinical data were collected through a semi-structured questionnaire. A venous blood sample was collected to determine the red blood cell parameters. A thin blood smear preparation was performed to examine blood morphology. In addition, direct wet mount and formalin-ether sedimentation techniques were used for stool examination to identify intestinal parasites. Data were entered into EpiData and exported to Stata 14 for statistical analysis. Descriptive statistics were presented in text, tables, and figures. A binary logistic regression model was used to identify factors associated with postpartum anemia. A p-value <0.05 was considered statistically significant. The proportion of postpartum anemia was 47.16%; 95% CI; 41.30-53.03 with moderate, mild, and severe anemia accounting for 45.11, 42.86, and 12.03%, respectively. The majority of the anemia (94%) was of the normocytic normochromic type. It was associated with postpartum hemorrhage (AOR = 2.23; 95% CI: 1.24-4.01), cesarean section (AOR = 4.10; 95% CI: 2.11-7.78), lack of iron and folate supplementation during pregnancy (AOR = 2.12; 95% CI: 1.17-4.02), and low diet diversity level (AOR = 1.83; 95% CI: 1.05-3.18). The prevalence of anemia was found to be a major public health concern. Iron and folate supplementation during pregnancy, improved management of PPH, an effective cesarean section with post-operative care, and taking a diversified diet will reduce the burden. Therefore, identified factors should be considered to prevent and control postpartum anemia.

A Five-Year Retrospective Investigation of the Prevalence of Intestinal Parasites at Mizan-Tepi University Teaching Hospital, Southwest Ethiopia.

Intestinal parasites are responsible for a significant amount of disease and mortality around the world. In developing nations, intestinal parasites are a severe public health issue. Intestinal parasite infections are one of the most common illnesses in the world. They're frequently linked to poor personal and environmental cleanliness, as well as low-quality drinking water. The aim of this study is to investigate the prevalence of intestinal parasites and their shifting trends during a five-year period at Mizan-Tepi University of Teaching Hospital (MTUTH). A cross-sectional retrospective survey using the past five years' (2017 to 2021) clinical records obtained from MTUTH Mizan-Aman town Southern west Ethiopia. Patients with complete age, sex, and stool parasite examination (direct wet mount or concentration techniques) records on the parasitology registration book were included. Data were entered and analysed using a Microsoft Excel sheet. The parasite prevalence was calculated using frequency and percentages. Overall, 17,030 patient records of the past five years were reviewed from the registration books of parasitology laboratory departments at MTUTH and only 546 records were taken for this study. Of these 336 (61.50%) were female and the rest 210 (38.50%) were males. One hundred eighty-two (182) 33.33% of patients had one or more intestinal parasites over five years from 2017 to 2021. From total of 546 patients' records 17.77% in 2017, 18.89% in 2018, 23.44% in 2019, 19.96% in 2020 and 19.96% in 2021 had complete information. Intestinal parasite prevalence was high among patients who visited the Mizan-Tepi University of Teaching Hospital during the five-year period. Helminthes and protozoan parasites prevalence was higher in the 15-45 years age category. In order to avoid intestinal parasite-related disease, strategies other than mass drug administration are required.
