摘要
为进一步掌握乳牛隐孢子虫病在河南省的流行动态，从河南省郑州、开封、济源和鹤壁4个地区9个奶牛场采集12月龄以内的乳牛粪便样品582份，用饱和蔗糖溶液漂浮法和改良抗酸染色法进行检测。结果显示，隐孢子虫总感染率为26．12％（152／582）。其中，断乳前犊牛（5日龄至2月龄）隐孢子虫感染率为30．91％（51／165），断乳后犊牛（3～12月龄）感染率为24．22％（101／417）。依据形态数值初步鉴定为2种隐孢子虫，即微小隐孢子虫和安氏隐孢子虫。微小隐孢子虫在断乳前犊牛阳性样品中的比率为50．98％（26／51），在断乳后乳牛阳性样品中的比率为9．90％（10／101）。另外，饲养方式（断乳前犊牛单独隔离饲养和未隔离饲养）对断乳前犊牛2种隐孢子虫的感染率有显著影响。
To further understand the prevalence of cryptosporidiosis in dairy calves in Henan Province, 582 fecal samples were collected from calves of less than 12-month-old on nine dairy farms in Zhengzhou, Kaifeng,Jiyuan and Hebi prefectures, and the samples were examined by the Sheater＇s sugar flotation technique and the modified acid-fast staining method. The overall infection rate was 26.12%（152/582） and the infection rate was 30.91%（51/165） in pre-weaning（5 days-old to 2 months-old） calves,and 24.22%（101/ 417） in post-weaning （3 to 12 months-old） calves, respectively. The parasites were identified to represent Cryptosporidiurn parvurn and C. andersoni preliminarily. The proportion of C. parvurn was 50.98 % in the pre-weaning calves,but only 9.90% in the post-weaning calves. Moreover, raising manners,including pre- weaning isolation raising and pre-weaning non-isolation raising, had significant influence on infection rates of the two Cryptosporidiurn species.
