Gastrointestinal helminths of Cattle slaughtered at Gwagwalada abattoir, federal capital territory, Nigeria

Gastrointestinal parasites are widespread in cattle worldwide, causing both clinical and sub-clinical infections that can lead to significant financial losses. This study investigated the prevalence of gastrointestinal helminths infection in cattle slaughtered in the abattoir at Gwagwalada area council, federal capital territory, Nigeria. A total of 120 faecal samples were collected and analysed by flotation and sedimentation methods. The results revealed an overall prevalence of 26.67%. The helminths identified were Toxocara sp (5.00%), Schistosoma sp (10.83%), and Fasciola sp (10.83%). These findings were compared to existing studies, with variations attributed to differences in climatic conditions, management practices, and seasonal factors. Age, breed, and sex-specific analyses revealed significant differences in infection rates. While no helminth infection was found in young adult cattle (1≤3 years), a 31.37% prevalence was recorded in older adult cattle (≥3 years). Among the breeds examined, Sokoto Gudali showed the highest prevalence (100%), followed by White Fulani (26.42%) and Red Fulani (16.67%). A significant breed-related difference (p = 0.0001) was recorded. Additionally, male cattle exhibited a higher prevalence (31.37%) compared to (0.00%) in females. The study highlighted the impact of geographical, ecological, and environmental factors on helminths infection, as well as the need for strategic anthelmintic treatment, improved livestock management, and educational programs to control these infections. Regular monitoring and selective breeding may further contribute to long-term infection control in cattle populations.

Roles of helminth extracellular vesicle-derived let-7 in host–parasite crosstalk

Helminth infections are a major public health problem as they can cause long-term chronic infections in their hosts for which there is no effective vaccine. During the long-term interaction between helminths and their hosts, helminth-derived extracellular vesicles (EVs) can participate in host immunomodulatory processes by secreting bioactive molecules (BMAs). Growing data suggests that microRNAs (miRNAs) in helminth EVs have a significant impact on the host’s immune system. The let-7 family is highly conserved among helminth EVs and highly homologous in the host, and its function in host–parasite crosstalk may reflect active selection for compatibility with the host miRNA machinery. In-depth studies targeting this aspect may better elucidate the mechanism of parasite-host interactions. Hence, this review summarizes the current studies on the cross-species involvement of helminth EV-derived let-7 in host immune regulation and discusses the barriers to related research and potential applications of helminth EVs.

Elevated circulating group-2 innate lymphoid cells expressing activation markers and correlated tryptase AB1 levels in active ascariasis

IntroductionAscaris lumbricoides infection is one of the most common soil-transmitted helminthiasis and IgE response to this helminth may increase the risk of asthma, bronchial hyperreactivity and atopy. There is not enough evidence showing the role of group-2 innate lymphoid cells (ILC2) in the pathogenesis of helminth infections in humans. Here, we aimed to investigate and characterize the influence of Ascaris lumbricoides infection on circulating ILCs in endemically exposed subjects.MethodsNon-infected (NI; n=16) and Ascaris-infected (AI; n=16) subjects from an endemic area were included. Two consecutive stool samples from each subject were examined by Kato-Katz to define parasite infection. Antibodies to the ABA-1 antigen of Ascaris and Ascaris extract were measured by ELISA. ILC subsets and their activation markers (CD25, CD69, thymic stromal lymphopoietin receptor (TSLPR) were evaluated in its PBMC by flow cytometry. Proximity extension assay (PEA) was performed to explore plasma proteins associated to infection.ResultsNo significant differences in the relative or absolute frequencies of total ILCs, ILC1, ILC2 and ILC3 cells were observed regarding the infection status. However, within AI group, IgE-sensitized subjects to ABA-1 had higher frequencies and counts of ILC2 (p<0.05). Frequencies of CD25+, CD69+ and TSLPR+ ILC2 were higher in AI compared to the NI (p<0.01). Additionally, egg burden was positively correlated with CD69+ ILC2 frequencies (r=0.67; p=0.005). Tryptase alpha/beta 1 (TPSAB1), GP6 and several plasma proteins associated with cell growth and granulocyte chemotaxis were highly expressed in the AI group (p<0.05). Interestingly, TPSAB1 levels were positively correlated with ILC2 expressing activation markers frequencies, egg burden and IgE levels against Ascaris.DiscussionAscaris infection is associated with increased expression of ILC2 activation markers and TPSAB1, which may contribute to the type-2 response.

Global burden of soil-transmitted helminth infections, 1990–2021

BackgroundSoil-transmitted helminth (STH) infections can cause a significant disease burden. It is estimated that 1.5 billion people worldwide are infected with STHs, primarily in tropical and subtropical regions. This study aimed to assess the distribution of the global burden and trend of STH infections from 1990 to 2021.MethodsWe retrieved data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 on the age-standardized rates (ASRs) of prevalence and disability-adjusted life-years (DALYs) of STH infections for all age groups in 204 countries and territories from 1990 to 2021. The ASRs of prevalence and DALYs by age, gender, and socio-demographic index (SDI) were calculated to quantify the spatial distribution and temporal trend. Spearman correlation analysis was used to examine the relationship between ASR and SDI.ResultsIn 2021, there were an estimated 642.72 million cases and 1.38 million DALYs caused by STH infections worldwide. The age-standardized prevalence rate (ASPR) of STH infections was 8429.89 [95% uncertainty interval (UI): 7697.23, 9362.18 ] per 100,000 population globally. The ASPR of STH infections varied across 21 geographic regions in 2021, being mainly prevalent in most African and Latin American locations. The prevalence was higher in the groups of 5–19 years, especially the group of 5–9 years with the ASPR of 16,263 (95% UI: 14,877.06, 18,003.49) and ASR of DALYs of 40.69 (95% UI: 25.98, 60.91) per 100,000. The ASPR of STH infections showed an obvious decreasing trend worldwide (estimated annual percent change = − 4.03, 95% confidence interval: − 4.13, − 3.93) with variations in different species infections during the study years. At the regional level, the ASR of STH infections prevalence (r = − 0.8807, P < 0.0001) and DALYs (r = − 0.9069, P < 0.0001) were negatively correlated with SDI .ConclusionsSTH infections remain a public health problem in 2021, particularly in regions such as the middle parts of Africa and Americas, and in the 5–19 age populations. The reduction in the rate of prevalence and the loss of DALYs are negatively correlated with the increase in SDI. Enhancing political commitment, providing accurate preventive chemotherapy, and advancing techniques for surveillance and mapping systems are essential to achieve the target of ending STH infections as a public health problem by 2030.Graphical

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 and Associated Risk Factors of Helminth Infections in the Digestive Tract of Camels in Xinjiang, China.

Camels, vital to economies in Asia, Africa, and the Arabian Peninsula, have been domesticated for over 4000 years. They thrive in arid regions like Xinjiang, China, but face challenges from internal and external parasites, particularly gastrointestinal parasites, which impact health, meat and milk quality, and production efficiency. This study investigates the prevalence of gastrointestinal helminth infections in camels from five major regions in Xinjiang. We collected 435 fresh fecal samples and used the saturated saline flotation method and McMaster's method for detection. Molecular examination followed. The overall prevalence was 18.2% (95% confidence interval [CI]: 14.7-22.2%), with Urumqi showing the highest prevalence (29%, 95% CI: 23.4-35.1%) compared to other regions (odds ratio [OR]: 4.62, 95% CI: 2.63-8.41%). Younger camels (≤3 years old) were more likely infected by the parasites after adjusting for the region differences (OR: 10.53, 5.12-24.65%). However, we found no evidence that the prevalence was different between male and female camels. PCR analysis identified Trichostrongylus spp., Chabertia ovina, and Haemonchus contortus as predominant parasites, with observed co-infections indicating a complex parasitic landscape. The findings provide essential epidemiological data for effective parasite control strategies.

Contribution of socio-demographic factors in prevalence of soil-transmitted helminth infections among newly arrived laborers in Jeddah, Saudi Arabia.

Soil-transmitted diseases are caused by intestinal worms transmitted via various routes into the human body resulting in various clinical manifestations. This study aimed to investigate the socio-demographic factors contributing mainly to the prevalence of soil-transmitted helminths (STHs) among newly arrived laborers in Jeddah, Saudi Arabia. A total of 188 stool specimens were collected and examined macroscopically and microscopically using different techniques. In addition, real-time PCR was used as a molecular tool to detect several STHs. The descriptive analysis was used to evaluate demographic data and categorical variables in association with STHs infection. Of all participants, the mean age was 26.08±2.67 years, including 103 females and 85 males. A total of 86 (45.70%) were illiterate, followed by 60 (31.90%) of participants belonging to elementary level. STHs and other intestinal parasites were detected among 35 newly arrived laborers (18.61%). Nineteen cases (10.11%) were infected with STHs, including 15 cases with one STHs (four A. lumbricoides, four N. americanus, four T. trichiura, two S. stercoralis, one A. duodenale) and four cases with two STHs (two T. trichiura and N. americanus; one S. stercoralis and A. duodenale; one T. trichiura and S. stercoralis). High rates of STHs infection were detected among drivers (11.70%) followed by housemaids (11.20%), but with no significant association to occupation. Higher rates of STHs infection were detected among those used to walk on soil barefoot in their home countries before arriving in Jeddah. This study found that none of the newly arrived expatriate laborers in Jeddah was aware of STHs. About 10% of them had infection with one or two STHs, mainly among newly arrived laborers from Asian countries. There is a need for awareness programs and regular screening for STHs and other intestinal parasites among newly arrived expatriate laborers.

Low prevalence of soil transmitted helminth infection in Ugandan children hospitalized with severe malaria.

Co-infection by intestinal helminths and Plasmodium spp. may be common in endemic communities. Several studies have identified a relationship between helminth infection, Plasmodium spp. infection and malaria severity. However, the relationship is not well defined, and results are inconclusive. We analyzed 202 stool samples from a cohort of children with severe malaria enrolled in two hospitals in Uganda from 2014-2017 and asymptomatic community children from the same household or neighborhood and enrolled at the same time, all 6 months to 48 months of age. We investigated if intestinal helminth infection modified risk of severe malaria. We extracted nucleic acids from stool and tested them for six helminth species ( Anyclostoma duodenale, Ascaris lumbricoides, Necator americanus, Strongyloides stercolaris, Trichuris trichiura, Shistosoma mansoni ) using highly sensitive quantitative PCR. We found a low prevalence of infection by ≥1 intestinal helminth species in children with severe malaria (5.1%, n=9/177) and community control children (4.0%, n=1/25). Infection by ≥1 of the helminths assessed was not associated with severe malaria (aRR = 1.0, 95% Confidence Interval = 0.82, 1.3, p = 0.78). In 2003 Uganda instituted a national deworming program, with anti-helminth medication provided twice annually to children 6 months to 5 years of age. In these areas of Uganda, the national deworming campaign has been highly successful, as stool-based helminth infection was rare even when using highly sensitive methods of detection and was not a major contributor to risk of severe malaria.

Immuno-therapeutic and prophylactic potential of Trichinella spiralis antigens for inflammatory bowel diseases

Ulcerative colitis (UC), a severe chronic inflammatory disorder of the colon, is one of the inflammatory bowel diseases (IBD) that affects humans and several domestic animal species, including cats and dogs. Helminth infections and autoimmune diseases are inversely correlated, as explained by the hygiene hypothesis, which suggests that IBD is infrequent in countries where helminth infections are common but more prevalent in developed nations. This study investigated the therapeutic and prophylactic potential of Trichinella spiralis (T. spiralis) antigens in an experimental colitis model for IBD. Mice were divided into eight groups: normal model, colitis model, larval antigen prophylaxis, adult antigen prophylaxis, larval antigen therapeutic, adult antigen therapeutic, larval antigen prophylaxis and therapeutic, and adult antigen prophylaxis and therapeutic. Colitis was induced intrarectally by administering a single dose of 0.2 ml of acetic acid, except in the healthy group, which received PBS (0.2 ml). The mice were euthanized 12 days after colitis induction. The therapeutic and prophylactic potential of T. spiralis antigens were assessed through colitis severity and histopathological, immunological, and immunohistochemical examinations. The results showed a significant reduction in Disease Activity Index (DAI), an increase in goblet cells' acidic mucin levels, reduced iNOS and TNF-α expression, and decreased serum levels of IFN-γ and IL-10 cytokines in Groups IV-VIII compared to the colitis model, particularly in the group that received adult worm antigen both prophylactically and therapeutically. This study demonstrated that T. spiralis antigens, especially from adult worms, had protective and therapeutic effects on experimental colitis, with a superior effect when administered both before and after colitis induction by reducing inflammation and modulating the immune response. Thus, T. spiralis antigens may improve disease outcomes and provide a novel treatment approach for ulcerative colitis.

Metabolic Shifts Induced by Helminth Infections and Their Contribution to Stunting in Vulnerable Populations

Aims: to revisit the condition of chronic metabolic shifting caused by immunomodulatory sequence facilitated by helminth infection together with other deteriorating condition such as persistent exposure to infection which contributes to stunting formation. Discussion: During dynamic interaction between active helminth infection and the host, the helminth and its excretory/secretory products induce and arouse the type 2 immune response which drives host tolerance and plays an important role in promoting tissue repair. Helminths also activates M2 Macrophages and induce a metabolic shift, even metabolic reprogramming towards reliance on oxidative phosphorylation, lipid oxidation and amino acid metabolism. Helminth-induced activation and metabolic reprogramming of macrophages precede the improvement in overall whole-body metabolism, denoted by improved insulin sensitivity, body mass in response to high-fat diet and atherogenic index in mammals. Contributions of altered nutrient uptake, adipose tissue function and/or the intestinal microbiota with the ability of helminths to alter metabolic status play a pivotal role in increased metabolism rate and may lead to wasting and even stunting formation. Conclusion: Helminth drives the type 2 immunity and activates its cell line which is responsible for metabolic shifting and reprogramming.

A Review to Illustrate the Concept of Krimi in Ayurveda

Background: Knowledge of Krimi and its description in Vedas and Ayurvedic Samhitas is very unique and different from the concept of worm in modern medical science. Krimi is a broad terminology in ancient Indian science which encompasses various types of helminths, microorganisms such as bacteria, viruses, fungi, and protozoa causing a large variety of diseases. Materials and Methods: A narrative review was conducted and result was presented under the result. Result and Discussion: Krimi Roga is one among the various diseases which must be paid prime attention in terms of Ayurveda management. Drugs and formulations from herbal sources play key role in management of these helminthic and parasitic infections. A majority of patients being from pediatric age segment, the knowledge of Krimi Roga management may bring a boon to pediatric ailments. Conclusion: Ayurveda believes in Prakriti (specific body constitution of the individual), if we can change the internal environment of the intestine (Kostha) through Apkarshana, Prakriti Vighata and Nidana parivarjana using appropriate drugs as well as enhancing the strength of Agni; then, affinity towards production and multiplication of Krimi may be arrested and hence, the ailments can be treated. Krimi is a condition, affecting all age groups, but children have always been at risk due to their playful activities and lack of maintenance of adequate personal hygiene. Once infected, the entire family may eventually get affected from the infected children.[1] If we consider Drishya Krimi as worm infestation, In India, more than 200 million children are infected on an average with roundworm, hookworm, etc. In Ayurveda, several causes (nidanas) have been mentioned for development of Krimi (microbes/worms) in human body like Ajirna (indigestion in GIT), Adhyashana (eating even when the previous meal has not been digested), Asatmyaahara, Virudhasana, Malinasana (incompatible foods or unhygienic meal habit), Avyayam (sedentary lifestyle), Diwaswapna (sleeping during the daytime), Guru (heavy), Atisnigdha (excessively fatty diet), Atisheet Ahara-Vihara (cold

The Recombinase Polymerase Amplification Test for Strongyloides stercoralis Is More Sensitive than Microscopy and Real-Time PCR in High-Risk Communities of Cusco, Peru.

Strongyloidiasis is a neglected, soil-transmitted helminth infection prevalent worldwide. The true burden of strongyloidiasis is unclear due to the lack of sensitive, field-friendly diagnostic tests. PCR tests to detect Strongyloides DNA in stool are sensitive and specific, but the need for expensive equipment limits their use in endemic regions. Isothermal PCR amplification tests are easier to deploy while maintaining sensitivity and specificity. We developed and evaluated a recombinase polymerase amplification lateral flow assay (RPA-LFA) to detect Strongyloides stercoralis in human stool samples. Three hundred stool samples were collected in three communities in the jungle of Cusco, Peru. Samples were tested for S. stercoralis larvae using microscopy (Baermann's, agar plate culture (APC), and rapid sedimentation), real-time PCR, and RPA-LF for Strongyloides DNA. The RPA-LFA showed an analytical limit of detection of 20 pg/µL. The prevalence of S. stercoralis was 27%, 38%, 46.3%, and 46% using microscopy, PCR, microscopy/PCR, and RPA-LFA, respectively. RPA-LFA had a sensitivity and specificity of 59.3% and 58.9%, 66.2% and 71.4%, and 77.2% and 73.1% when microscopy, microscopy/PCR, and real-time PCR were used as the gold standards, respectively. The Strongyloides RPA-LFA is a novel, fast, highly sensitive, and specific molecular method with the potential for deployment in endemic regions.

Animal health as a function of farmer personality and attitude: using the HEXACO model of personality structure to predict farm-level seropositivity for Fasciola hepatica and Ostertagia ostertagi in dairy cows.

Infections with Fasciola hepatica and Ostertagia ostertagi impinge upon dairy cow health and welfare and represent a major economic factor in livestock industry. Control measures largely rely on the use of anthelminthic drugs. However, reports of anthelmintic resistance necessitate sustainable approaches. Farmer characteristics such as attitude and personality are crucial for the implementation of control strategies and on-farm practices. In the present study, the HEXACO (Honesty-Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness to experience) model of personality structure, which conceptualizes human personality, was used to evaluate the relationship of farmer aspects with on-farm bulk tank milk seropositivity for F. hepatica and O. ostertagi. Moreover, information on farm structure, housing, management, and farmers' attitude was collected in a face-to-face interview. Farm-level seropositivity for F. hepatica and O. ostertagi was predicted via elastic net regression. Out of 193 farms housing 8,774 cows in the German Federal State of Bavaria, 47 farms (24.4%) were seropositive for F. hepatica, 77 farms (39.9%) for O. ostertagi, and 42 farms (21.8%) for both endoparasites. The model for F. hepatica seropositivity selected the covariates pasture access, O. ostertagi seropositivity, higher farmer conscientiousness, and organic farming as relevant predictors. Seropositivity for O. ostertagi was predicted by F. hepatica seropositivity, pasture access, organic farming, and farmers being neutral regarding their satisfaction with animal health on their farm. Higher values for the HEXACO factors extraversion and emotionality were inversely associated with O. ostertagi seropositivity. The present work emphasizes the importance of farmer traits in regard to animal health and parasite occurrence. For the effective acceptance and implementation of sustainable control strategies for livestock helminth infections, it is crucial to consider these aspects to holistically address the challenges of managing parasitic diseases. Moreover, tailored communication strategies can be developed incorporating the understanding of individual stockman characteristics and subsequently ensuring encouragement of stakeholders.

Routine screening and clinical diagnosis of intestinal helminths in cats and dogs

Anthelmintics remain a fundamental component of both treatment of parasitic disease and preventative health for pets. The focus of intestinal helminth control to reduce disease and zoonotic risk in the UK has been routine treatment rather than testing. As a result, testing is often viewed as unnecessary if routine preventative treatment is occurring. Diagnosing intestinal roundworms in cases of gastrointestinal disease is important because heavy burdens can contribute to the severity of clinical signs and intestinal pathology. However, routine testing alongside prevention for worm infections in cats and dogs is also vital to demonstrate the effectiveness of treatment plans, gather data on parasite distributions and detect anthelmintic resistance.

The first survey of endoparasite infection in the brown rat (Rattus norvegicus) from a synanthropic environment in Hungary

Urban rats are significant reservoirs of zoonotic endoparasites, posing serious health risks to humans. This study aimed to detect common endoparasites in wild brown rats (Rattus norvegicus) in Budapest, addressing the current lack of endoparasite surveys in Hungary. Carcasses of 131 rats collected following extermination were examined. Three zoonotic helminths were identified: Hymenolepis nana and Hymenolepis diminuta in the jejunum, and Calodium hepaticum in the liver. Additionally, non-zoonotic parasites were detected, including Eimeria spp., Entamoeba muris, Heterakis spumosa, Nippostrongylus brasiliensis, Eucoleus gastricus, Aonchotheca annulosa, Syphacia muris (intestine), and Trichosomoides crassicauda (urinary bladder). Helminth infection prevalence was 83.9 %, with no noticeable differences in prevalence or infection intensity between sexes. These findings highlight the potential public health risk posed by zoonotic parasites in urban rat populations, emphasising the importance of surveillance to mitigate possible human infection. The findings indicate that rats from Budapest harbour similar parasites to those in neighbouring regions. Further large-scale studies are recommended to better understand the parasitic landscape in Hungary's rat populations, leveraging data from rat control programs.

KORELASI PERILAKU HIDUP BERSIH DAN SEHAT DENGAN KECACINGAN PADA SISWA SEKOLAH DASAR DI KABUPATEN PROBOLINGGO

Background: Soil-transmitted worms are still a health problem in Probolinggo Regency, especially related to clean and healthy living behavior. Health and hygiene education is an effort to reduce worm transmission and infection. The purpose of this study was to identify clean and healthy living behaviors related to worms. Method: The study design was observational analytic with a Cross-Sectional Study approach. The population was elementary school students in Probolinggo Regency with a sample size of 607 students taken by cluster sampling with a single-stage method. Identification was carried out on clean and healthy living behaviors and the number of worm eggs in feces and soil. Data analysis used Chi Square with an alpha of 0.05. Results: The data showed that 96.4% of respondents were negative and 3.6% were positive with a distribution of worm eggs of 2.1% Ascaris lumbricoides, 1.3% Hookworm and 0.5% Trichuris trichiura with mild infection intensity. The results of the Chi Square test showed no relationship between washing hands before eating, washing hands after defecating, wearing footwear, and nail conditions with worms in students with p values of 0.748, 0.584, 0.550, 0.777, respectively. Conclusion: These results are due to the history of exposure and the body's immunity in overcoming parasite invasion. Long exposure to children with positive worms will make the parasite colony maintain a clean and healthy lifestyle. Conversely, low exposure and strong immunity keep children free from worm infections.

Evaluation of Enterobius Vermicularis Infection in Primary School and Relationship with Nocturnal Enuresis

Enterobiasis or pinworms infection is one of the most prevalent worms found in children worldwide . There was a possible association between certain infection and the propensity to develop nocturnal enuresis including intestinal helminthes infection. Prospective study included (100) randomly selected children aged range (6-12) years from both sex, have been acquired from primary schools in the center of Al-Kut city. The children were examined for E.vermicularis infection by microscopic examination .Total positivity rate of Enterobiasis among children from 6 -12 years was 14% &amp; the number of positive sample were 14 out of 100 child examined .37 (16.2%) were males and 63 (12.6%) were females..Males had a slightly higher prevalence than females However, difference was non-Significance (NS) P&gt;0.05. The results showed the highest prevalence (28.57 %)in the group age 6 years , while the lower infection rate was found in the group age 10-12 years (0%), The statistical analysis showed significant differences at the level of 0.05 between the age groups. E. vermicularis is one of the most common intestinal helminthes with nocturnal enuresis among children in Al-Kut city., there are no significant differences (NS) P&gt;0.05 between males and females for Enterobius vermicularis infection and nocturnal enuresis.

Persistent transmission of soil-transmitted helminths despite 16 years of uninterrupted Mebendazole- and ivermectin-based preventive chemotherapy in the Lomie Health District (East Region, Cameroon): The emergency of complementary control strategies.

The control of the Soil-Transmitted Helminths (STH) infections primarily relies on the school-based Preventive Chemotherapy (PCT) with mebendazole. Given the efficacy of ivermectin on STH, the control of the latter is expected to be potentialized in areas where ivermectin is also distributed for onchocerciasis and/or lymphatic filariasis control/elimination. This study aimed to assess the prevalence and intensity of STH in the Lomie Health District where annual school-based deworming campaigns and community-directed treatments with Ivermectin have been underway for almost two decades. A quantitative cross-sectional study was conducted in 10 schools of the Lomie Health District, East Region, Cameroon. Stool samples were collected from school-aged children and analysed using the Kato-Katz technique. Semi-structured questionnaires were administered to enrolees to assess compliance with water, sanitation, and hygiene (WASH). Of the 491 children (median age: 9 years; IQR: 7-10) enrolled, 83.9% (95% CI: 80.3-87.1) were infected with at least one STH species. Trichuris trichiura was the predominant species (78.5%), and no hookworm was found. The prevalence trend slightly decreased between 1987 and 2010 (~8%) and remained unchanged since 2010 (p-value = 0.05). Overall, 46.8% and 41.8% of children were heavy-to-moderately infected with Ascaris lumbricoides and T. trichiura. Poor hand hygiene (OR: 2.24, 95% IC: 1.4-3.4, p-value = 0.0002) and the use of river as a source of drinking water (OR: 14.8, 95% IC: 6.9-33.3, p-value = 0.0001) were the main risk factors associated with the STH infection in Lomie Health District. The persistent high prevalence and intensity of STH infection despite 16 years of mebendazole-based PCT and expected collateral impact of ivermectin mass distribution, points to plausible implementation gaps, poor compliance to WASH or sub-optimal efficacy of the anthelminthics used. This study highlights the need to further assess the cause of the persistent high prevalence and implement context-adapted control measures in order to curb STH transmission.

Intestinal Protozoa, Helminth Infection, and Associated Factors among Tuberculosis Patients and Nontuberculosis Persons in Bobo-Dioulasso City, Burkina Faso.

We report the frequency and associated factors of tuberculosis (TB) and parasite coinfection from newly diagnosed pulmonary TB patients (TB+) and non-TB participants (TB-) from the Regional Tuberculosis Control Center, households, and health facilities in Bobo-Dioulasso from 2019 to 2021. Biological samples were examined for parasite infection using direct microscopy, concentration techniques, and the immunochromatographic rapid test. Data were analyzed using STATA 14. Of a total of 192 participants involved, 95 were TB+ and 97 were non-TB. There was no statistically significant difference in parasitic infections between the two groups, although it was higher in TB+ than TB- (69.5% [66/95] versus 55.7% [54/97]; P = 0.07). Protozoal infection prevalence was significantly higher in patients with TB+ than in those TB- (61.1% versus 37.1%; P = 0.001). Specifically, Entamoeba spp. and Cryptosporidium spp. followed this pattern with 35.8% versus 19.6% (P = 0.01) and 22.1% versus 8.3% (P = 0.007), respectively. Although higher in TB+ patients, helminthiasis frequency was not significantly different between the two groups (23.2% versus 15.5%; P = 0.2). Helminth species were Schistosomia mansoni (17.9% versus 12.4%), Dicrocoelium dendriticum (3.2% versus 1.0%), Enterobius vermicularis (2.1% versus 2.1%), Wuchereria bancrofti (1.1% versus 0.0%), and Hymenolepis nana (1.1% versus 0.0%). Illiteracy (adjusted odds ratio [aOR]: 2.5; 95% CI: 1.0-6.1), smoking (aOR: 2.4; 95% CI: 1.1-5.3), and handwashing after defecation (aOR: 2.4; 95% CI: 1.2-4.7) were associated with parasites. This study reported a high frequency of parasite coinfection in TB patients. These findings suggest the need for adequate health education for behavioral change and systematic diagnosing of parasites in TB patients for better coinfection management.

Communities’ knowledge, perceptions and preventive practices on soil-transmitted helminthes in Jimma, Oromia, Ethiopia: Formative mixed study

Background Soil-transmitted helminthes (STH) infections are one of the most common neglected tropical diseases. It has become one of a significant public health problem programmatically aimed for prevention and control in Ethiopia. Limited evidence is available on communities’ knowledge, perceptions, and practices regarding STH particularly in rural settings of Jimma, Ethiopia. Methods A community-based cross-sectional study triangulated with the qualitative method was conducted. The survey included 732 sampled rural households. Linear regression was used to assess association between predictors of knowledge and preventive practices of STH; likewise logistic regression was used to identify the predictors of hand washing practice at critical times. Kruskal-Wallis and Mann-Whitney tests were done to test differences in median risk perception score by socio-demographic factors. Qualitative data were collected through 7 key informant interviews, 6 focus group discussions and 7 expert group discussions then transcribed verbatim. Then, the data were coded, categorized and thematized using the Atlas ti.7.1.4 software package. Results Almost all of the respondents (99.6%) had heard of STH. The prevalence of comprehensive knowledge, risk perception and preventive practices towards STH were 46.7%:(95%CI:43.2, 50.4), 55.2%: (95%CI:51.2,59) and 44.4%:(95%CI:40.8, 48.2) respectively. Likewise, the magnitude of knowledge and practice of hand washing at critical times were 42.5%: (95%CI: 38.7,45.9) and 43.9%: (95%CI: 40, 47.5) respectively. Risk perception and comprehensive knowledge towards STH varied significantly across districts and by respondents’ educational status. Ownership of improved latrine was associated to comprehensive knowledge of STH. The STH preventive practice that varied across districts was predicted by the overall and knowledge specific to washing hands at critical times. The practice of washing hands at critical times was significantly associated to knowledge of hand washing, owning improved latrine, and age from 15 to 34 year compared to &gt;45 year. Moreover, qualitative findings were supportive of the findings. Conclusion Despite reported exposures to STH communication opportunities, the study found modest levels of knowledge, perceptions, and preventive practices related to STH among rural communities where the burden of STH was the programmatic concern. These levels of knowledge, perceptions, and practices varied across the districts. Educational and latrine status predicted overall knowledge, whereas knowledge specific to hand washing and overall knowledge were predictors of STH preventive practice. Furthermore, washing hands during critical times was moderately improved among the young-aged, ownership of improved latrine and knowledgeable on hand washing. This study underscores the need for locally tailored and contextualized community behavioral change interventions needs to be strengthened toward improved STH preventive practices.
