Diarrhea is the most frequently diagnosed disease in Swiss cow-calf farms. During an longitudinal study conducted in 105 cow-calf farms in Switzerland in 1993-95, blood and fecal samples were collected from diarrheic calves and from calves that died because of diarrhea. Campylobacter spp. were detected in 42%, E. coli (VTEC) in 32%, rotavirus in 33%, coronavirus in 13%, coccidia in 43% and helminths in 8% of the cases. In some samples Yersinia pseudotuberculosis were isolated. The BVD-virus antigen was not detected in any of the calves examined. In most cases concurrent infection with several enteropathogens was diagnosed. Specific causes of diarrhea were therefore difficult to establish. The bacteriological findings of this study have implication for food safety: VTEC, Campylobacter spp. Yersinia spp. and cryptosporidia are considered as potential causes on zoonoses.
腹泻是瑞士奶牛犊牛养殖场中最常被诊断出的疾病。在1993年至1995年于瑞士105个奶牛犊牛养殖场进行的一项纵向研究中，从腹泻犊牛和因腹泻死亡的犊牛身上采集了血液和粪便样本。弯曲杆菌属在42%的病例中被检测到，肠出血性大肠杆菌（VTEC）在32%的病例中被检测到，轮状病毒在33%的病例中被检测到，冠状病毒在13%的病例中被检测到，球虫在43%的病例中被检测到，蠕虫在8%的病例中被检测到。在一些样本中分离出了假结核耶尔森菌。在所检查的任何犊牛中均未检测到牛病毒性腹泻病毒抗原。在大多数病例中，诊断出同时感染了几种肠道病原体。因此，腹泻的具体病因难以确定。本研究的细菌学发现对食品安全有影响：肠出血性大肠杆菌、弯曲杆菌属、耶尔森菌属和隐孢子虫被认为是人畜共患病的潜在病因。
