Campylobacter fetus subsp. jejuni was commonly present in the feces of unweaned calves (2 to 3 weeks old) and from two of four groups of sheep. One new season lamb (12 to 16 weeks old) carried the organism, but the bacteria were not isolated from cattle. With unweaned calves, the fractions of animals infected and carcasses contaminated were similar. Contamination of carcasses usually involved low densities of C. fetus subsp. jejuni (ca. 1 to 10/cm2), which were isolated from flank but not rump areas. The organism was recovered less frequently from chilled carcasses and deboned veal. Small numbers of C. fetus subsp. jejuni could be recovered from equipment during the processing of unweaned calves but not after routine cleaning.
胎儿弯曲菌空肠亚种常见于未断奶犊牛(2至3周龄)的粪便中,以及四组绵羊中的两组。一只新一季的羔羊(12至16周龄)携带该病菌,但未从牛身上分离出这种细菌。对于未断奶犊牛,感染动物的比例和胴体受污染的比例相似。胴体污染通常涉及低密度的胎儿弯曲菌空肠亚种(约1至10个/平方厘米),这些细菌是从胁腹部位而非臀部区域分离出来的。从冷藏胴体和去骨小牛肉中较少分离到该病菌。在未断奶犊牛加工过程中,能从设备上回收少量胎儿弯曲菌空肠亚种,但在常规清洁后则无法回收。
