A mycoplasma-like organism was isolated from five cows with chronic incurable mastitis from one dairy herd. This organism was shown to be Mycoplasma californicum and was used to infect three cows by intramammary inoculation. The challenge organism was reisolated from all the infected quarters and the ensuing inflammatory response produced a chronic mastitis with a permanent drop in milk yield. Antibiotic treatment in one animal was unsuccessful.
从一个奶牛群中患有慢性顽固性乳腺炎的5头奶牛身上分离出一种类支原体微生物。该微生物被鉴定为加利福尼亚支原体,并通过乳房内接种感染了3头奶牛。从所有受感染的乳腺中重新分离出攻击微生物,随后产生的炎症反应导致了慢性乳腺炎,产奶量永久性下降。对其中一头奶牛进行抗生素治疗未成功。
