Survey and genetic characterization of wastewater in Tunisia for Cryptosporidium spp., Giardia duodenalis, Enterocytozoon bieneusi, Cyclospora cayetanensis and Eimeria spp.
The microbial diversity of wastewater used for irrigation and fertilization was assessed using specific polymerase chain reaction (PCR) assays to detect and genotype several pathogenic protists including Cryptosporidium spp., Giardia duodenalis, Cyclospora spp., Eimeria spp. and Enterocytozoon bieneusi. A total of 220 wastewater samples (110 raw, 110 treated) and 12 sludge samples were collecte...
متن کاملMolecular Surveillance of Cryptosporidium spp., Giardia duodenalis, and Enterocytozoon bieneusi by Genotyping and Subtyping Parasites in Wastewater
BACKGROUND Despite their wide occurrence, cryptosporidiosis and giardiasis are considered neglected diseases by the World Health Organization. The epidemiology of these diseases and microsporidiosis in humans in developing countries is poorly understood. The high concentration of pathogens in raw sewage makes the characterization of the transmission of these pathogens simple through the genotyp...
متن کاملCryptosporidium spp., Giardia intestinalis, and Enterocytozoon bieneusi in Captive Non-Human Primates in Qinling Mountains
Non-human primates (NHPs) are confirmed as reservoirs of Cryptosporidium spp., Giardia intestinalis, and Enterocytozoon bieneusi. In this study, 197 fresh fecal samples from 8 NHP species in Qinling Mountains, northwestern China, were collected and examined using multilocus sequence typing (MLST) method. The results showed that 35 (17.8%) samples were positive for tested parasites, including Cr...
متن کاملPrevalence of Eimeria spp., Cryptosporidium spp. and Giardia spp. in calves in the Van province.
This research was carried out in order to determine the prevalence of Eimeria spp. Cryptosporidium spp. oocysts and Giardia cysts in calves less than 6 months of age in Van province. For this purpose, fecal samples were obtained from the rectum of 182 calves. Fecal samples (n: 182) were examined with the modified acid-fast technique for Cryptosporidium spp. oocysts. The same samples were examin...
متن کاملPrevalence and genetic characterization of Cryptosporidium, Enterocytozoon, Giardia and Cyclospora in diarrheal outpatients in china
BACKGROUND Cryptosporidium spp., Enterocytozoon spp., Giardia spp. and Cyclospora spp. are important intestinal protozoan parasites causing diarrhea in humans, livestocks and wildlife and have a significant impact on public health. No reports exist about simultaneous prevalence rates or genotyping data of these four parasites in outpatients from China. METHODS Fecal specimens from 252 diarrhe...
