Twelve herds of dairy cows were examined by rectal swabbing for the presence of Campylobacter jejuni. Ten herds were positive with the incidence of colonized animals ranging from 10 to 72% of those tested. With the exception of the two negative herds where mains water only was consumed, all animals drank from rivers or streams when grazing. There was no relationship between total and coliform counts and the presence of C. jejuni in raw milk. However, milk from one farm that consistently gave positive results had significantly higher Escherichia coli counts than other samples.
通过直肠拭子检查了12群奶牛,以检测空肠弯曲菌的存在。10群奶牛呈阳性,被感染动物的发生率在检测动物的10%至72%之间。除了仅饮用自来水的两群阴性奶牛外,所有动物在放牧时都饮用河流或溪流中的水。生牛奶中的总菌数和大肠菌群数与空肠弯曲菌的存在之间没有关系。然而,一个农场的牛奶 consistently 给出阳性结果,其大肠杆菌计数明显高于其他样本。 (注:“consistently”这里翻译为“一直”,放在句中语义稍显奇怪,原文可能有误,推测应该是“constantly”,“持续地” )
