Exploring interactions between Blastocystis sp., Strongyloides spp. and the gut microbiomes of wild chimpanzees in Senegal.

Exploring interactions between Blastocystis sp., Strongyloides spp. and the gut microbiomes of wild chimpanzees in Senegal. Infect Genet Evol. 2019 Aug 20;:104010 Authors: Renelies-Hamilton J, Noguera-Julian M, Parera M, Paredes R, Pacheco L, Dacal E, Saugar JM, Rubio JM, Poulsen M, Köster PC, Carmena D Abstract BACKGROUND: Gut parasites exert an important influence on the gut microbiome, with many studies focusing on the human gut microbiome. It has, however, undergone severe richness depletion. Hygienic lifestyle, antimicrobial treatments and altered gut homeostasis (e.g., chronic inflammation) reduce gut microbiome richness and also parasite prevalence; which may confound results. Studying species closely related to humans could help overcome this problem by providing insights into the ancestral relationship between humans, their gut microbiome and their gut parasites. Chimpanzees are a particularly promising model as they have similar gut microbiomes to humans and many parasites infect both species. AIMS: We study the interaction between gut microbiome and enteric parasites in chimpanzees. Investigating what novel insights a closely related species can reveal when compared to studies on humans. METHODS: Using eighty-seven faecal samples from wild western chimpanzees (Pan troglodytes verus) in Senegal, we combine 16S rRNA gene amplicon sequencing for gut microbiome characterization PCR detection of parasite taxa (Blastocystis sp., Stron...

AbstractGiardia intestinalis andBlastocystis spp. are two common zoonotic intestinal parasites responsible for the majority of diarrheic cases, especially in children. The study was planned to determine the impact role of bothGiardia andBlastocystis co-infection in children up to 12  years old with acute diarrhea in Beni-Suef, Egypt. Also, to estimate the general prevalence rates and risk factors associated with intestinal parasitic infections. Stool samples collected from 125 children, within a period of 7 months, were examined using direct wet mount and trichrome stain in c omparison to in vitro culture on Jone...

Conclusion: High rate of intestinal parasites particularly, S. stercoralis compared to the most recent studies of general population. Therefore, regular screening and tracking the positive cases, disinfection of the living environment, training and financing of the staff, increasing the number of the workers, recruiting of professionals and trained personnel in these centers are suggested.

Abstract Unawareness of canine parasitic diseases among at-risk hosts and an uncontrolled program of stray dog population have caused that zoonotic parasites received great attention in endemic regions of the Middle East. A total of 552 faecal samples were collected between December 2016 to January 2018 from stray (n = 408) and domestic (n = 144) dogs of Iran. All specimens were coproscopically observed following concentration and flotation techniques. Subsequently, the DNAs of taeniid eggs were extracted, amplified, and sequenced by targeting of mitochondrial cytochrome oxidase subunit...

This study aimed at determining the epidemiology of strongyloidiasis using sensitive microscopy testing in rural populations living at different altitudes in Cusco, Peru. Data were collected from subjects aged> 3 years living in Quellouno (elevation 2,600 ft) and Limatambo (elevation 8,379 ft) districts. Subjects provided one fresh stool sample and answer a standardized questionnaire. Fresh stool was tested on site using the Baermann's test and agar plate culture. Formalin-preserved stool was tested by rapid sedimentation. Eighty percent (585/715) of eligible subjects consented to participate; after excluding subjects w...

Conclusion: It was determined that, pathogen parasites such as G. intestinalis and A. lumbricoides were still observed at high rates in Van province, especially in children, and the problem of parasitosis is still continuing, although the prevalence of parasites has declined when compared to the previous years.

This study aimed to analyze the occurrence of intestinal parasites among Mayan children from the villages of Xkalakdzonot and Paraíso in Yucatán State. Stool samples from 83 children were examined using two coproparasitological tests (formalin-ethyl acetate concentration and FLOTAC Pellet techniques). The overall prevalence of intestinal parasites in children was 65.1%. Six protozoa and four helminths were identified. Blastocystis sp. (44.6%), Giardia intestinalis (26.5%), and Entamoeba coli (26.5%) were the most prevalent parasites. The prevalence of helminth infections (7.1%) was lower in children from Xkal...

Abstract Objective: Food handlers play an important role in the production and distribution of parasitic contaminations in these societies. The aim of this study was to assess the prevalence of intestinal parasitic infections among the food handlers in Qazvin, Iran. Methods: Totally, 1530 stool samples were collected from food handlers in Qazvin, Iran. Direct feces examination and formalinethyl acetate concentration method followed by Trichrome staining were performed to detect the parasites. Results: The prevalence of intestinal parasites was 82 (5.4%) among food handlers. The species of protozoan paras...

ConclusionIn conclusion, we have found, despite persistent improvement in sanitary conditions over the recent years in northern part of Iran, IPIs are still among the main public health problems in this area. Moreover, helminths infection in our study were considerable. Thus, effective control programs are essential to reduce the incidence of IPIs.

Conclusion: The high rate of infection with Blastocystis hominis was found in cancer patients especially colorectal cancer patients, so careful consideration should be given by physicians. Cryptosporidium sp was found to be the major cause of parasitic intestinal infection in patients with organ transplant compared to primary immunodeficiency patients; so transplant recipients undergoing immunosuppressive therapy should be considered as a risk group for acquiring microsporidiosis and Cryptosporidium infection.
