Abstract
Five quarters of the udders of two lactating cows were infected by intramammary inoculation with Campylobacter coli/jejuni in doses ranging from 2.6 colony-forming units (c.f.u.) to 3.8 X 10(9) c.f.u. The infected quarters developed clinical mastitis and the campylobacters were reisolated in large numbers from the milk. The milk from the uninfected quarters, and blood and faeces remained free of the organisms. The campylobacters could only be isolated by incubation of culture plates in a microaerobic atmosphere. The results showed that C. coli/jejuni can cause mastitis in the cow and that the bovine udder is a potential source of C. coli/jejuni in raw milk.
摘要
通过乳房内接种不同剂量（2.6个菌落形成单位（c.f.u.）至3.8×10⁹ c.f.u.）的空肠弯曲菌/结肠弯曲菌，对两头泌乳奶牛的五个乳房象限进行感染。受感染的乳房象限发生了临床乳腺炎，并且从牛奶中大量重新分离出弯曲杆菌。未受感染乳房象限的牛奶、血液和粪便中未检测到该微生物。弯曲杆菌只能通过在微需氧环境中培养平板来分离。结果表明，空肠弯曲菌/结肠弯曲菌可导致奶牛患乳腺炎，并且奶牛乳房是生牛奶中空肠弯曲菌/结肠弯曲菌的潜在来源。
