Histopathological investigation and risk factors of Coccidiosis in camels (Camelus dromedarius), Algeria

Coccidiosis in dromedaries is an intestinal protozoan infection caused by apicomplexan parasites belonging to the genus Eimeria. A prospective examination was conducted at two slaughterhouses in southern Algeria. The primary objective of this investigation was to ascertain the prevalence of intestinal parasites in camels, elucidate the associated microscopic lesions, and identify the risk factors contributing to this infestation. In pursuit of this, we procured four segments of the intestines from 31 dromedarieas that appeared healthy and displayed no symptoms. Subsequently, these samples were collected, preserved, subjected to routine processing, and subsequently stained with haematoxylin and eosin (H&E). Intestinal parasitic infection showed an incidence rate of 45.16% (14 out of 31). Specifically, two types of parasites were discerned in the intestinal specimens through microscopic examination, namely Eimeria (41.93%; 13 out of 31) (p-value = 0.046) and Taenia (3.22%; 1 out of 31) (p = 0.001). Eimeria cameli was observed in the ceacum (41.93%; 13 out of 31), jejunum (12.90%; 4 out of 31), and in one instance in the duodenum (3.22%; 1 out of 31). Furthermore, numerous development stages of coccidia were identified, including gamonts, schizonts and oocysts. Deep microscopic lesions attributed to Eimeria cameli were detected, such as enteritis, eosinophilic infiltration and inflammation. In addition, associated risk factors were identified. This study has furnished valuable insights into parasitic infestations affecting dromedaries, particularly Eimeria cameli. The molecular studies are needed to delineate the diverse variations within Eimeria strains. Effective parasite control strategies specific to dromedary camels need to be developed.

Prevalence Study of the Intestinal Protozoal Parasitic Infections Rates at Babylon and Kerbala Cities

Intestinal protozoa are parasites transmitted by the consumption of contaminated water and food and mainly affect children and older people and cause considerable health problems. They are leading to causes of outpatient morbidity in developing countries due to diarrhea. The aim of this study was invetigation the prévalence of Entamoeba histolytica and Giardia lamblia parasites at Kerbala and Babylon cities in 2022. The research was conducted during the period starting from 1/1/2021 until 31/12/2021 in the provinces of Babylon and Kerbala. The Imam Al-Sadiq Hospital in Babylon and the AlHusseini Hospital in Karbala were taken. Data were collected in both hospitals to detect the spread of the disease (E.histolytica) and they were taken. Considering the percentage of injuries for age groups and gender of the injured during the months of the year. Results of this study showed that rates of intestinal parasitic infections at the Hospitals of Babylon City at Imam Sadiq Hospital, while the total infection rates was 6.58% While the total infection rate with the same parasite at Al-Hashimiya Hospital was 29%. At Hospitals of Kerbala city, the total infection rate at Al-Hussein Hospital was 21.37% While the rate of infected people at Al-Husseiniya Hospital was 26.4% The results of infection rates with Giardia lamblia in the current study showed the following:- At hospitals of Babylon city the total infection rate was 14.3% When it reached Imam Sadiq Hospital, the infection rate was 1.72% While the rate of infection in Al-Hashimiya Hospital was: 1.69% At hospitals of Kerbala city the infection rate was in Al-Hussein Hospital 1.83% While the rate of infected people was at Al-Husseiniya Hospital 2.21% The total infection rate was .4..% as the infection rate was in Al-Hussein Hospital 1.83%, while the infection rate in Al-Husseiniyah Hospital was 2.21%.

Detection of Sarcocystis albifronsi, Eimeria alpacae, and Cystoisospora felis in Eurasian lynx (Lynx lynx) in northwestern China

Eurasian lynx (Lynx lynx) is widely distributed in various habitats in Asia and Europe, and it may harbor multiple pathogens. Currently, the information on protozoan infection in Eurasian lynx is scarce. In this study, we performed nested polymerase chain reaction (nPCR) analysis to detect intestinal protozoan infection in three dead Eurasian lynxes, in northwestern China. Three dead Eurasian lynxes, an adult female (#1), an adult male (#2), and a cub male (#3), were sampled in West Junggar Mountain, the northwestern region of Xinjiang Uyghur Autonomous Region. The intestine samples were analyzed using nPCR. We used primers targeting the cytochrome C oxidase subunit I gene (COI) for detection of Sarcocystis and Eimeria species and targeting the small subunit 18 S ribosomal RNA gene (18S rRNA) for detection of Cystoisospora species. The nPCR-positive products were sequenced, aligned, and phylogenetically analyzed. Three intestinal protozoa, Sarcocystis albifronsi, Eimeria alpacae, and Cystoisospora felis, were found in three Eurasian lynxes. The intestine sample of Eurasian lynx #2 was detected with S. albifronsi and E. alpacae. In addition, C. felis was only found in the intestine sample of Eurasian lynx #3. To the best of our knowledge, S. albifronsi and E. alpacae were detected in Eurasian lynx for the first time. In addition, C. felis was firstly found in Eurasian lynx in China. These findings extend our knowledge of the geographical distribution and host range of intestinal protozoa.

Epidemiology and Molecular Characterization of Zoonotic Gastrointestinal Protozoal Infection in Zoo Animals in China.

Zoo animals, harboring zoonotic gastrointestinal protozoal diseases, pose potential hazards to the safety of visitors and animal keepers. This study involved the collection and examination of 400 fresh fecal samples from 68 animal species, obtained from five zoos. The aim of this study was to determine the occurrence, genetic characteristics, and zoonotic potential of common gastrointestinal protists. PCR or nested PCR analysis was conducted on these samples to detect four specific parasites: Cryptosporidium spp., Giardia duodenalis, Enterocytozoon bieneusi, and Blastocystis spp. The overall prevalence of Cryptosporidium spp was 0.5% (2/400), G. duodenalis was 6.0% (24/400), Blastocystis spp. was 24.5% (98/400), and E. bieneusi was 13.5% (54/400). G. duodenalis, Blastocystis spp., and E. bieneusi were detected in all of the zoos, exhibiting various zoonotic genotypes or subtypes. G. duodenalis-positive samples exhibited three assemblages (D, E, and B). Blastocystis spp. subtypes (ST1, ST2, ST3, ST4, ST5, ST8, ST10, ST13, and ST14) and one unknown subtype (ST) were identified. A total of 12 genotypes of E. bieneusi were identified, including SC02, BEB6, Type IV, pigEBITS 7, Peru8, PtEb IX, D, CD9, EbpC, SCBB1, CM4, and CM7. Moreover, significant differences in the positive rates among different zoos were observed (p < 0.01). The findings indicate that zoo animals in China are affected by a range of intestinal protozoa infections. Emphasizing molecular identification for specific parasite species or genotypes is crucial for a better understanding of the zoonotic risk. Preventing and controlling parasitic diseases in zoos is not only vital for zoo protection and management but also holds significant public health implications.

Cryptosporidiosis Detection Using Immunoglobulin a Serum with Enzyme-Linked Immunosorbent Assay Method

Background: Cryptosporidiosis is still one of the most common intestinal protozoan infections found in developing countries, affecting children and adults. Cryptosporidium sp. infection activates the immune response by secreting high levels of specific Cryptosporidium IgA antibodies during the infection process. IgA can be examined by ELISA to establish a diagnosis of cryptosporidiosis. Methods: The purpose of this study was to determine the results of Cryptosporidiosis detection with serum IgA ELISA. This study was a quantitative descriptive study with 39 samples collected from children to adults using consecutive sampling technique. Data obtained from the study results were processed by univariate analysis and presented in tabular form to see the frequency distribution. Result: The results of the study involving 39 respondents revealed that the most prevalent age groups were 6-11 years old and 36-45 years old, with the majority being female. Among the 39 samples examined using the ELISA method, the Optical Density ranged from 0.059 to 1.393. One sample (2.56%) tested positive for IgA Cryptosporidium sp., specifically from age 55 years (16.6%) and male participants (20%). Conclusion: The study concluded that the Optical Density value of the positive ELISA examination was 1.393 with one sample found positive for Cryptosporidiosis from a 55 years old male.

Evaluation of a rapid immunochromatographic test for the diagnosis of intestinal protozoan infections among patients attending a rural outreach outpatient department in Northern India.

Despite great efforts, intestinal protozoan infections remain a significant healthcare concern worldwide. Although many point-of-care (POC) tests are increasingly being used, microscopic examination of stool specimens remains the mainstay for their diagnosis, especially in resource-limited settings. We assessed the utility of rapid POC tests based on immunochromatography among patients from rural Northern India. A total of 78 patients were enrolled in the study. Out of nine specimens that tested positive for Giardia duodenalis on microscopy, an immunochromatographic test (ICT) could detect only five (55.55%). Entamoeba histolytica/dispar was demonstrated in two specimens on microscopy, both of which were missed by ICT. Its overall sensitivity, specificity, and positive and negative predictive value were 50%, 98.5%, 83.3%, and 93%, respectively. Its performance was considered unsatisfactory. Although ICT-based tests provide a relatively rapid and less labor-intensive alternative, they should be used to supplement and not replace stool microscopy.

Human protozoa infection and dysplasia in ulcerative colitis: a neglected aspect in a prominent disease

The chance of getting colorectal cancer (CRC) is higher in people with chronic ulcerative colitis (UC). The impact of parasitic infections on UC is underappreciated. The purpose of this study was to look into the effect of intestinal protozoal infections on the dysplastic changes generated by UC. The research included 152 adult patients with histologically confirmed UC and 152 healthy controls. Fecal samples were examined for the presence of parasites and fecal calprotectin (FC). The enzyme-linked immunosorbent assay measured serum anti-p53 antibodies (p53Abs) and metallothioneins (MTs). The advanced oxidation protein products (AOPPs) and reduced glutathione (GSH) levels were measured by a spectrophotometric method in all subjects. Serum C-reactive protein (CRP) and IL-6 were also measured. In addition, histopathological and immunohistochemical investigations of intestinal tissue were done. Our results exhibited significant increases in FC and CRP, IL-6, AOPPs, MTs, and p53Abs in ulcerative colitis patients with parasitic infections compared to those without parasites. In contrast, GSH levels showed a significant decrease in the same group compared with other groups. Histopathological and immunohistochemical assessments of intestinal tissue signified severe inflammation and strong expression of PD-L1 in patients with parasitic infections compared to others without parasitic infections. Our research indicated a greater frequency of intestinal protozoa in UC patients with elevated inflammatory and dysplastic biomarker levels. This suggests that these parasites may be involved in the etiology of chronic UC and the associated carcinogenetic process. This is the first report of a link between parasitic infections and dysplastic alterations in UC patients.

Some of them had bacterial infections that were diagnosed in hospital laboratories But they

Environmental Sanitation as Risk Factors for Intestinal Protozoa Infection among Stunted Children in Sugerkidul Village, Indonesia

Stunting, a prevalent health issue in Indonesia, has been found to have a significant impact on the overall well-being of children, with a prevalence rate of 24.4%. This condition not only affects physical growth but also puts children at a heightened risk of various infections, including those caused by intestinal protozoa. Therefore, this study aimed to determine the relationship between personal hygiene parenting style and environmental sanitation with intestinal protozoa infection among stunted children in Sugerkidul Village, Jember District, Indonesia. The participants included were 30 stunted children. Questionnaires were used to collect data on personal hygiene parenting style and environmental sanitation, while microscopic stool examination was conducted to identify intestinal protozoa infection. The results showed that 26.7% of stunted children were infected with intestinal protozoa such as Giardia lamblia (13.3%), Blastocystis hominins (3.3%), and Cryptosporidium parvum (10%). Statistical analysis using Fisher's exact test showed a significant association between environmental sanitation and intestinal protozoa infection. However, there was no association between personal hygiene parenting style and this infection among stunted children in Sugerkidul Village. Therefore, to prevent intestinal protozoa infection, it is necessary to improve environmental sanitation.&#x0D;

Evaluation of the Performance of the Novodiag® Stool Parasites Assay for the Detection of Intestinal Protozoa and Microsporidia.

We aimed to assess the performance of the Novodiag® Stool Parasites (NSP) assay in the diagnosis of the most common intestinal protozoan and microsporidia infections. A panel of 167 selected stool samples was retrospectively analysed with the NSP assay and compared to routine microscopy and qPCR methods for the detection of pathogenic protozoa and microsporidia. Whereas specificity was high for all protozoa and microsporidia, NSP sensitivity was strongly dependent on the comparative method used as reference. When compared to microscopic methods, NSP sensitivity was high (96.7 to 100%) for Blastocystis hominis, Entamoeba histolytica and Cyclospora cayetanensis but was lower for Giardia intestinalis (85.2%) and ≤50% for Cystoisospora belli and Dientamoeba fragilis. In comparison to conventional qPCR, the NSP assay demonstrated lower sensitivity characteristics dependent on parasite loads, reaching 60 to 70% for G. intestinalis, D. fragilis, Cryptosporidium spp. and E. histolytica. Sensitivity was 100% for Enterocytozoon bieneusi, but none of the five samples containing Encephalitozoon spp. were detected. The overall performance of the NSP assay in the diagnosis of gastrointestinal protozoa and microsporidia seems to be better than or equivalent to that observed with microscopic methods but inferior to that obtainable with classical targeted qPCR.

Community-Led Total Sanitation: Conceptual Approach to Intestinal Parasites Control in Rural Areas, Cote d’Ivoire

Lack of appropriate sanitation, with poor hygiene and unsafe water, are sources of the spread of diseases. Ongoing efforts to control neglected tropical diseases, including helminth and intestinal protozoan infections, must be maintained and strengthened with new approaches. The aim of this study was to test the adherence of communities to the Community-Led Total Sanitation (CLTS) approach. The study was conducted in three (3) departments in south- central C&amp;ocirc;te d&amp;#39;Ivoire. In practice, the process of implementing CLTS involves 5 major steps: i) Mapping of defecation areas, ii) Calculating of human fecal matter quantity and medical costs, iii) Walk of shame, iv) Analysis of contamination pathways, v) Community decision making and latrine construction. Overall, latrine coverage and usage rates have increased considerably in the intervention localities. In particular, out of the 26 localities where the CLTS was applied, 11 reached a latrine coverage rate higher than 80%, 6 of which reached a 100% coverage rate. The results of this work should be used to raise awareness in rural communities about the importance of building and using latrines. Furthermore, CLTS implemented on a large scale can contribute to achieving Goal 3 and 6 of the Sustainable Development Goals (SDGs).

The incidence of laboratory-confirmed cases of enteric pathogens in Denmark 2018: a national observational study

Background Only a subset of enteric pathogens is under surveillance in Denmark, and knowledge on the remaining pathogens detected in acute gastroenteritis is limited. Here, we present the one-year incidence of all enteric pathogens diagnosed in Denmark, a high-income country, in 2018 and an overview of diagnostic methods used for detection. Methods All 10 departments of clinical microbiology completed a questionnaire on test methods and provided 2018-data of persons with positive stool samples with Salmonella species, Campylobacter jejuni/coli, Yersinia enterocolitica, Aeromonas species, diarrheagenic Escherichia coli (Enteroinvasive (EIEC), Shiga toxin-producing (STEC), Enterotoxigenic (ETEC), Enteropathogenic (EPEC), and intimin-producing/attaching and effacing (AEEC)), Shigella species., Vibrio cholerae, norovirus, rotavirus, sapovirus, adenovirus, Giardia intestinalis, Cryptosporidium species, and Entamoeba histolytica. Results Enteric bacterial infections were diagnosed with an incidence of 229.9 cases/100,000 inhabitants, virus had an incidence of 86/100,000 and enteropathogenic parasites of 12.5/100,000. Viruses constituted more than half of diagnosed enteropathogens for children below 2 years and elderly above 80 years. Diagnostic methods and algorithms differed across the country and in general PCR testing resulted in higher incidences compared to culture (bacteria), antigen-test (viruses), or microscopy (parasites) for most pathogens. Conclusions In Denmark, the majority of detected infections are bacterial with viral agents primarily detected in the extremes of ages and with few intestinal protozoal infections. Incidence rates were affected by age, clinical setting and local test methods with PCR leading to increased detection rates. The latter needs to be taken into account when interpreting epidemiological data across the country.

Global prevalence of intestinal protozoan parasites among food handlers: A systematic review and meta-analysis

Food handlers with improper personal hygiene practices have a significant role in transmitting foodborne parasites, including intestinal protozoa. The current systematic review and meta-analysis aimed to evaluate the global prevalence of intestinal protozoan parasites among food handlers. Multiple databases (PubMed, Scopus, Pro-Quest, Web of Science, Science Direct, and Google Scholar) were explored for relevant literature published from 1988 to April 2022. Pooled prevalence was estimated using the meta-package in R (version 3.6.1). One hundred thirty-eight papers, including 259,364 individuals, were considered in this study. The global pooled prevalence (95% confidence interval) was 0.143% (0.118–0.170%). The highest pooled prevalence was observed in the Western Pacific WHO Region (0.318%, 0–1.000%). The most prevalent protozoa was Blastocystis hominis (0.077%, 0.046–0.115%). Moreover, among different countries, Gambia had the highest pooled prevalence (0.501%, 0.459–0.544%). The prevalence of intestinal protozoan parasites estimated in the present study revealed that food handlers highly impact the global population. Periodic stool screening is necessary for food handlers to prevent intestinal protozoan infection. Additionally, a health education programme to raise awareness regarding food hygiene is recommended.

Malarial and intestinal parasitic co-infections in indigenous populations of the Brazilian Amazon rainforest

The Brazilian Amazon rainforest region has a significant prevalence of malarial and intestinal parasitic infections in indigenous populations, accounting for a disproportionate burden. Thus, a cross-sectional study was conducted to assess the prevalence and association between malarial and intestinal protozoan and helminth infections in four remote indigenous villages in the Brazilian Amazon Forest. A total of 430 individuals participated in the study, and Plasmodium infections were diagnosed by examination of thick blood smears and PCR. Stool samples 295 individuals (69%) were examined by direct smear and the Kato–Katz technique. The overall prevalence of malaria, intestinal protozoan infection, and intestinal helminth infection was 14.2%, 100%, and 39.3%, respectively. Polyparasitism was predominant (83.7%), and most infected individuals had at least two or more different species of intestinal protozoan and/or helminth parasites. The prevalence of co-infection was 49.5%, and in individuals with intestinal protozoa and helminth infections (34%), Entamoeba. coli, Entamoeba histolytica, and Ascaris lumbricoides were the most common parasites. In individuals with malaria and protozoa infections (10.2%), P. vivax, E. coli, and E. histolytica predominated, and in individuals with malaria, protozoa, and helminth infections (5.4%). P. vivax, E. coli, E. histolytica, and A. lumbricoides predominated. Intestinal polyparasitism was common in the study population, and the presence of helminths was associated with an increased number of intestinal parasitic species. However, Plasmodium infections were neither a risk nor a protective factor for helminth infections; the same was true for helminth infections in relation to Plasmodium. The high prevalence of intestinal polyparasitism with Plasmodium co-infections highlights the need for combining strategies that may help control both malaria and intestinal parasite and generate a health approach aligned with indigenous perspectives.

Epidemiological Profile of Intestinal Protozoan Infection in Dakar, Senegal: Results from Hospital-Based Survey

Background Intestinal parasitic infections, especially intestinal protozoan parasites remain significant public health problem in Senegal. Several studies have demonstrated the endemicity of the diseases. The study was carried out with the objective of assessing the epidemiolocal profile of intestinal protozoan infection diagnosed among patients attending to Fann University Hospital in Dakar, Senegal. Materials and Method A retrospective study was conducted from 2016 to 2020. Samples were collected from patients attending to the laboratory for parasitological confirmation. Fresh stool samples were observed using direct examination, formal-ether concentration method and modified Zeilh Nielsen staining method. Descriptive analysis was performed using Stata MP 16 software. The significance level was set at 5%. Results Among 3825 patients selected in the study, 1009 were found with at least one intestinal protozoan parasite representing an overall prevalence of 26.4% (CI 95% (24.7– 28)). Mono-parasitic and di-parasitic infection represent 81.6% and 18.2% respectively while polyparasitism was observed in 26 patients representing 2,6%. Among positive samples, 16 (8.7%) were associated with helminths. Blastocystis sp. (40.8%), Entamoeba Coli (38.2%), Endolimax nana (8.2%) and Giardia intestinalis (8.1%) were mainly observed. Trophozoites Entamoeba histolytica was observed with 2.3%. Frequency of intestinal protozoa was higher in the 15 – 30 age group (28.3%) and in male group (26.9%). The parasite carriage was most important during the wet season comparing the dry season (p = 0.65). Asymptomatic patients (29.5%) were more infected than symptomatic patients (23.5%) (p &lt;10-3). The main clinical symptoms were diarrhea, abdominal pain, dysenteric syndrome, fever, dyspeptic disorders, and vomiting. Conclusion These results showed that intestinal protozoan infections remain prevalent in Senegal with a high proportion of asymptomatic who constitute an important reservoir of parasites. Effective control strategies such as water supply, hands washing, and mass deworming campaign could reduce the prevalence of these diseases.

Retrospective Assessment of The Intestinal Protozoan Distribution in Patients Admitted to The Hospital Aristide Le Dantec in Dakar, Senegal, from 2011 to 2020

Infectious parasites, especially the intestinal protozoan parasites, continue to be a major public health problem in Africa, where many of the same factors contribute to the transmission of these parasites. This study was conducted to investigate the parasites causing intestinal protozoal infections diagnosed in Aristide Le Dantec hospital (Senegal). Direct examination and the Ritchie technique were used. Among the 3407 stool samples studied, 645 demonstrated the presence of intestinal protozoa in single parasitism, biparasitism, or polyparasitism, representing a prevalence of 18.93%. Out of a total of 645 protozoa, 579 (16.99%) were identified in monoparasitism in the following order: Entamoeba coli (6.87%) and Blastocystis hominis (5.69%) for low pathogenic species, and Entamoeba histolytica/dispar (2.31%) and Giardia intestinalis (1.32%) for pathogenic species. The rates of biparasitism and polyparasitism were 1.88% and 0.06%, respectively. The highest rate of parasites was 24.83% between the ages of 0–15 years. A logistical regression model indicated that intestinal protozoan infections were not associated with age groups. There was an association between age groups and Giardia intestinalis and Blastocystis hominis (p &lt; 0.05). These results demonstrated the frequency of intestinal protozoa in Senegal. There is a need to implement treatment, prevention, and control measures to limit the circulation of these protozoan infections.

Physical Water Quality and Intestinal Protozoa Contamination on Household Water in Ajung District, Jember Regency

Intestinal protozoa infections are still a major health problem in worldwide. The prevalence of intestinal protozoa infections are relatively high in countries facing lack of safe drinking water and lack of suitable sanitation facilities. Lack of sanitation facilities, open defecation, and contamination of environmental feces can make water quality worse, both in terms of physically, chemically, and biologically. Physical water quality is poor when the household water used daily does not meet the standard parameters of the physical water quality standard. The purpose of this study was to determine the relationship between physical water quality and intestinal protozoa contamination in household water in Ajung District, Jember Regency. This type of research is an observational analytic study with a cross sectional research design. The research method used is the correlation method, namely the relationship between physical water quality and intestinal protozoa contamination in household water. The population in this study is household water in Ajung District, Jember Regency. Data analysis consisted of univariate analysis to see the distribution and percentage of temperature, total dissolves solid, color, odor, and intestinal protozoa contamination in household water, and then bivariate analysis using the Chi-square test to analyze physical water quality and intestinal protozoa contamination. The conclusion is there is a relationship between physical water quality and intestinal protozoa contamination in household water.
