An acute outbreak of mastitis and arthritis in a herd of 700 goats required the destruction of all but the few animals that were held for observation. The milk of nearly all of about 400 lactating does contained almost pure cultures of Mycoplasma putrefaciens with counts in 150 samples up to 1 X 10(9) colony forming units/ml. At post mortem examination the joints of both the adults and kids contained a fibrinopurulent discharge. M putrefaciens was isolated in pure cultures and large numbers from joints, tissues and fluid not previously known to harbour this mycoplasma: brain, kidneys, lungs, lymph nodes, uterus and urine. The outbreak was milkborne and initiated by infusion of the pathogen into the teat canal by poor hygiene in the milking parlour and by feeding raw colostrum to kids. All but 12 of the herd of 700 goats were killed or sold for slaughter.
一群700只山羊中突发乳腺炎和关节炎，除了几只留作观察的动物外，其余的都被销毁了。在约400只泌乳母羊中，几乎所有母羊的乳汁都含有几乎纯培养的腐败支原体，150份样本中的菌数高达1×10⁹菌落形成单位/毫升。尸检时，成年羊和小羊的关节都有纤维蛋白脓性分泌物。从关节、组织和此前未知携带这种支原体的液体（大脑、肾脏、肺、淋巴结、子宫和尿液）中分离出了纯培养且数量众多的腐败支原体。此次疫情是通过挤奶厅卫生条件差将病原体注入乳头管以及给小羊喂生初乳经乳汁传播引发的。700只山羊群中除12只外全部被宰杀或出售以供屠宰。
