An organism recovered from mastitic milk of a newly freshened goat was identified as Mycoplasma agalactiae. The number of mycoplasmas in the mammary secretions was 6.3 x 10(7) colony-forming units/ml, indicating active infection. This was the second recovery of M agalactiae in the United States, but in contrast to the previous isolate from the joint of a goat reported to be avirulent following experimental inoculation, the large concentration of M agalactiae from mastitic milk is evidence that it possesses pathogenic potential.
从一只刚产犊的山羊患乳腺炎的乳汁中分离出的一种微生物被鉴定为无乳支原体。乳腺分泌物中的支原体数量为6.3×10⁷菌落形成单位/毫升，表明存在活跃感染。这是美国第二次分离到无乳支原体，但与之前从一只山羊关节处分离出的菌株不同，据报道该菌株经实验接种后无毒力，而从患乳腺炎的乳汁中分离出的大量无乳支原体证明它具有致病潜力。
