cervine genotype is the major cryptosporidium genotype in sheep in china.to identify cryptosporidium species/genotypes in sheep in china and to elucidate the endemic transmission of cryptosporidiosis, a total of 1,701 fecal samples from five farms in four prefectures in henan province (central china) were examined. eighty-two cryptosporidium-positive samples were analyzed by polymerase chain reaction (pcr)-restriction fragment length polymorphism analysis of the small subunit (ssu) rrna gene and pcr analysis of the 60 kda glycoprotein (gp60) gene, and 41 were further ...201019904561
seroprevalence of toxoplasma gondii infection and risk factors in domestic sheep in henan province, central china.sheep are highly susceptible to infections with toxoplasma gondii and play a major role in the transmission of toxoplasmosis to humans. in the present study, 779 serum samples from sheep were collected from henan province, central china from march 2015 to may 2016, and antibodies to t. gondii were detected by modified agglutination test (mat). the overall seroprevalence of t. gondii in sheep was 12.71% (99/779). the risk factors significantly associated with t. gondii seroprevalence were the geo ...201627882868
