A total of 206 attaching and effacing Escherichia coli strains from ruminants were analysed for the presence of the astA (EAST1) and bfpA genes. None of these strains was bfpA-positive. The percentage of enteropathogenic E. coli (EPEC) strains astA-positive found in healthy cattle (15.6%) suggests that this animal species may be a significant reservoir of atypical EPEC potentially pathogenic for humans.
对总共206株来自反刍动物的黏附和损伤性大肠杆菌菌株进行了astA（EAST1）和bfpA基因检测。这些菌株均未检测到bfpA阳性。在健康牛中发现的肠致病性大肠杆菌（EPEC）菌株astA阳性率为15.6%，这表明该动物物种可能是对人类具有潜在致病性的非典型EPEC的重要宿主。
