The present review reports the prevalence studies carried out in bovine cryptosporidiosis in European countries in the last decade, including the molecular background when available. In foreground, the distribution of Cryptosporidium species, genotypes and C. parvum subtype families (alleles) in cattle are described in the twenty countries where molecular studies have been conducted. Surveys ca...

To estimate the prevalence and public health significance of cryptosporidiosis in preweaned calves in China, 801 fecal samples from eight farms in seven areas in Henan Province were examined for Cryptosporidium oocysts. The overall infection rate of Cryptosporidium was 21.5%, with the farm in Xinxiang having the highest prevalence (40%). No significant difference in infection rates was observed...

Sources of contamination such as animal feces runoff, organic fertilizer application, and the release of partially treated or untreated sewage can lead to the contamination of aquatic environments by Cryptosporidium spp. The quality of mussels as food is closely related to the sanitary conditions of the marine environment where these bivalves are found. Marine mollusks are filter feeders that a...

Background & Aims: Cryptosporidiosis is one of the most important parasitic zoonoses of human and animals. This infection is common in mammals and caused by the coccidian parasites of the genus Cryptosporidium. The Present study was designed to determine the epidemiology of Cryptosporidium infection in cattle in Kerman by using conventional morphological as well as molecular methods for molecul...

Parasites from the Cryptosporidium genus are the most common cause of waterborne disease around the world. Successful management and prevention of this emerging disease requires knowledge of the diversity of species causing human disease and their zoonotic sources. This study employed a spatiotemporal approach to investigate sporadic human cryptosporidiosis in New South Wales, Australia, betwee...

In this study, nine C. muris and 43 C. andersoni isolates from various animals in China were subtyped by a multilocus sequence typing (MLST) tool. DNA sequence analyses showed the presence of 1-2 subtypes of C. muris and 2-6 subtypes of C. andersoni at each of the four loci (MS1, MS2, MS3, and MS16), nine of which represented new subtypes. Altogether, two C. muris and 10 C. andersoni MLST subty...

To evaluate the presence of Cryptosporidium spp. and Giardia duodenalis in the influent and final effluent of sixteen drinking water treatment plants located in a hydrographic basin in Galicia (NW Spain) - in which the principal river is recognised as a Site of Community Importance (SCI) - estimate the efficiency of treatment plants in removing these protozoans and determine the species and gen...

24 25 To estimate the prevalence and public health significance of cryptosporidiosis in 26 pre-weaned calves in China, 801 fecal samples from eight farms in seven areas in 27 Henan Province were examined for Cryptosporidium oocysts. The overall infection 28 rate of Cryptosporidium was 21.5%, with the farm in Xinxiang having the highest 29 prevalence (40%). No significant difference in infection...

BACKGROUND Cryptosporidium spp. and Giardia duodenalis are important gastrointestinal protists in humans and animals worldwide. In China, bovine cryptosporidiosis and giardiasis are of increasing concern because cattle are important reservoirs of these parasites, which have become potential threats to public health and to large numbers of cattle in recent years. RESULTS A total of 1366 fecal ...
