比氏肠细胞虫被认为是艾滋病患者引发腹泻的机会性感染的病原体，在许多免疫功能正常的患者和包括牛在内的各种动物中也发现了这种细菌。在本研究中，我们检测了牛病毒性腹泻病毒（BVDV）（免疫抑制性牛病毒性腹泻（BVD）的最常见病原体）是否会增加E.牛中的bieneusi。采用ELISA法对6个奶牛场进行了研究，以检测采集血清中的BVDV抗体或抗原。共检测了来自四个年龄组的240份粪便样本中是否存在大肠杆菌。bieneusi。对6个E. bieneusi阳性样本显示存在E. bieneusi，以前在牛中描述过。E.本研究未证实BVDV阳性牛群中存在毕氏E.在捷克共和国的牛中的bieneusi。(C)2012爱思唯尔有限公司保留所有权利。
Enterocytozoon bieneusi known as a causative agent of opportunistic infections instigating diarrhoea in AIDS patients was identified also in a number of immunocompetent patients and in a wide range of animals, including cattle. In the present study we tested if the Bovine Viral Diarrhea Virus (BVDV), the most common pathogen underlying immunosuppressive Bovine Viral Diarrhoea (BVD), can enhance the occurrence of opportunistic infections with E. bieneusi in cattle. Six dairy farms were investigated using ELISA to detect antibodies against or antigens arising from BVDV in collected sera. A total of 240 individual faecal samples from four age groups were examined for the presence of E. bieneusi by nested PCR. Sequence analysis of six E. bieneusi positive samples revealed the presence of the genotype I of E. bieneusi, previously described in cattle. The hypothesis expecting higher prevalence of E. bieneusi in BVDV positive cattle herds was not confirmed in this study; however this is the first description about E. bieneusi in cattle in the Czech Republic.
