() and () are protozoan parasites that cause severe disease in animals and significant economic losses for farmers worldwide. is considered to be a serious parasite for dairy cows, while infection is a serious parasitic disease that can infect people and livestock. The aim of the present study was to investigate the seroprevalence of and in dairy cows in Hebei province, China. A total of 723 dairy cow sera samples from three regions in Hebei were analyzed by enzyme-linked immunosorbent assays (ELISA). The results revealed that 19.92% (144/723) of the individual serum samples were seropositive for , 37.34% (270/723) of the individual serum samples were seropositive for , and 8.7% (63/723) of the individual serum samples were seropositive for mixed infection. A higher seroprevalence of was found in the present study, when compared to previous data. To the best of the author's knowledge, the present study is the first to detect and antibodies in the vast areas of Hebei province, China.
（某原虫1）和（某原虫2）是原生动物寄生虫，可在动物中引发严重疾病，并给全球养殖户造成重大经济损失。（某原虫1）被认为是奶牛的一种严重寄生虫，而（某原虫2）感染是一种可感染人和牲畜的严重寄生虫病。本研究的目的是调查中国河北省奶牛中（某原虫1）和（某原虫2）的血清阳性率。采用酶联免疫吸附测定法（ELISA）对来自河北省三个地区的723份奶牛血清样本进行了分析。结果显示，19.92%（144/723）的个体血清样本对（某原虫1）呈血清阳性，37.34%（270/723）的个体血清样本对（某原虫2）呈血清阳性，8.7%（63/723）的个体血清样本对混合感染呈血清阳性。与先前数据相比，本研究中发现（某原虫2）的血清阳性率更高。据作者所知，本研究是首次在中国河北省广大地区检测到（某原虫1）和（某原虫2）抗体。
