Abstract:
... This study investigated 319 fecal specimens of cats (n=52) and dogs (n=267) from Heilongjiang province, China for the prevalence and genetic characteristics of Cryptosporidium, Enterocytozoon bieneusi, and Giardia duodenalis. PCR and DNA sequence analysis of the small subunit rRNA gene identified C. felis and C. parvum in one cat each (3.8%) and C. canis and C. ubiquitum in 6 dogs (2.2%). Polymorp ...

Abstract:
... Enterocytozoon bieneusi is a well-known causative agent of microsporidial infections in a variety of mammal hosts including humans in China, whereas there were no epidemiological data on wild animals bred in captivity, and the role of the neglected hosts in transmission of zoonotic microsporidiasis remains unknown. Herein, we investigated feces from 191 farmed foxes (Vulpes vulpes) and 162 farmed ...

Abstract:
... This study screened 151 pet-derived fecal specimens randomly collected from four commercial markets in northeast China for the presence of Cryptosporidium by genus-specific nested PCRs of the small subunit rRNA gene. Of these, 14 specimens (9.3 %) from nine species of birds, two types of rodents, and a hedgehog were positive for Cryptosporidium. Sequence analysis on the PCR-positive isolates facil ...
