Major progress has been made in understanding the epidemiology of bovine Cryptosporidium in China in the past 30 years. The overall infection rate in that period was 14.50% (5265/36316), with different prevalence being observed among dairy cattle, yaks, beef cattle, and buffalo. The infection rate declined as the animals' ages increased and the lowest prevalence occurred in winter. Ten Cryptosp...

Feces collected from 541 milking cows on two dairy farms each in Vermont, New York, Pennsylvania, Maryland, Virginia, North Carolina, and Florida were examined for the presence of Cryptosporidium oocysts. Oocysts were concentrated from 15 g of feces from each cow and DNA was extracted. A two-step nested PCR protocol was used to amplify an 830 base pair fragment of the SSUrRNA gene. PCR-positive...

Cryptosporidium is a protozoan parasite of medical and veterinary importance that causes gastroenteritis in a variety of vertebrate hosts. Several studies have reported different degrees of pathogenicity and virulence among Cryptosporidium species and isolates of the same species as well as evidence of variation in host susceptibility to infection. The identification and validation of Cryptospo...

Purpose: The purpose of this study is to model Cryptosporidiosis in laboratory animals. The parasites were inoculated into animalsand thenmultiplied. The process of proliferation was compared to controlCryptosporidiosis in humans. Materials and Methods: Twenty-five laboratory mice (4-7 days of age) and twenty-five laboratory rats (5 days of age) were assigned to the category I while the cat...

The burden of cryptosporidiosis due to Cryptosporidium parvum is well documented in HIV-positive patients in Ethiopia. However, the role of animals in zoonotic transmission of the disease is poorly understood. The aim of this study was to determine the prevalence and genotypes of Cryptosporidium species in dairy calves; to assess the role of cattle in zoonotic transmission in central Ethiopia. ...
