The prevalence of Cryptosporidium and the possibility of zoonotic transmission on dairy farms were examined. Eighteen cases of cryptosporidiosis (prevalence 6%) were identified in 82 farm workers and 207 household members. Furthermore, 70 (34%) of 207 calf samples were positive. Based on the 70kDa heat shock protein and the 18S rDNA gene, Cryptosporidium parvum was identified in 75% of the positive farm workers and in 60% of the household members. Of the positive calves, 62% were infected with C. parvum, indicating a possible zoonotic transmission on these farms.
对奶牛场隐孢子虫的流行情况以及人畜共患传播的可能性进行了调查。在82名农场工人和207名家庭成员中，确诊了18例隐孢子虫病（患病率6%）。此外，207份犊牛样本中有70份（34%）呈阳性。基于70kDa热休克蛋白和18S rDNA基因，在75%的阳性农场工人和60%的家庭成员中鉴定出微小隐孢子虫。在阳性犊牛中，62%感染了微小隐孢子虫，表明这些农场可能存在人畜共患传播。
