BACKGROUND Cryptosporidium hominis and C. parvum are usually considered to be the major pathogens responsible for human cryptosporidiosis. However, there have been few studies regarding the molecular epidemiology of Cryptosporidium in human infections in China. Here we investigated Cryptosporidium infection in patients with diarrhea, in Danyang Hospital of Jiangsu Province, China, at the genoty...

The present study examined the prevalence and genotypes of Cryptosporidium andersoni in cattle in Shaanxi province, China. A total of 2071 fecal samples (847 from Qinchuan cattle and 1224 from dairy cattle) were examined for the presence of Cryptosporidium oocysts, and 70 samples (3.4%) were C. andersoni-positive and those positive samples were identified by PCR amplification of the small subun...

Cattle are frequently parasitized with an number of protozoan parasites but Giardia duodenalis, Cryptosporidium parvum and Cryptosporidium andersoni are of major zoonotic concern. These parasites case diarrhoea and impair body weight gain. Giardia and Cryptosporidium from cattle are potential zoonotic pathogens and contact with animals, manure or contaminated water is believed to lead to infect...

We isolated oocysts that resemble Cryptosporidium andersoni from cattle grazing on a farm in Japan. The partial sequences of genes from the isolate were coincident with published sequences of genes of C. andersoni. Since the isolate was able to infect SCID mice, the isolate appears to be a novel type of C. andersoni.

background: as a waterborne pathogen, cryptosporidium is one of the most common causes of gastroenteritis in human and hoofed livestock animals. this study aimed to investigate the distribution of cryptosporidium spp. in human and livestock wastewaters in iran, by the 18s rrna sequence analysis. methods: a total of 54 raw wastewater samples collected from three urban treatment plants and two sl...

Cryptosporidium andersoni and Cryptosporidium muris infections have been found in the mice and/or cattle. The oocysts of C. andersoni and C. muris have been sporadically detected in human feces, but the infectious capacity and features have been unknown, because of the scarcity of reports involving human infections. To assess the infectivity and the clinical and pathological features of C. ande...

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...

Cattle are the main reservoir host of C. andersoni, which shows a predominance in yearlings and adults of cattle. To understand the subtypes of C. andersoni and the population genetic structure in Heilongjiang Province, fecal specimens were collected from 420 dairy cattle and 405 beef cattle at the age of 12-14 months in eight cattle farms in five areas within this province and were screened fo...

The present study describes the complete development of all life cycle stages of Cryptosporidium andersoni in the HCT-8 cell line. The in vitro cultivation protocols were the same as those used for the successful growth of all life cycle stages of Cryptosporidium parvum (Int. J. Parasitol. 31 (2001) 1048). Under these culture conditions, C. andersoni grew and proliferated rapidly with the compl...
