An outbreak of clinical mastitis is described in which 75 cows of a herd of 200 Friesian cows were affected in one or more quarters over a period of three months. Sixty animals failed to return to normal despite various intramammary and systemic antibiotic treatments. Heifers, dry cows and lactating animals were affected. The milk of 15 out of 53 animals tested yielded mixed cultures of Mycoplasma bovigenitalium and Acholeplasma laidlawii. Thirteen of 34 sera showed evidence of antibodies to A laidlawii.
描述了一次临床乳腺炎的爆发，在一个拥有200头弗里斯兰奶牛的牛群中，75头奶牛在三个月的时间里一个或多个乳腺区受到影响。尽管进行了各种乳房内和全身抗生素治疗，仍有60头牛未能恢复正常。小母牛、干奶期母牛和泌乳期动物均受到影响。在检测的53头动物中，有15头的牛奶培养出牛生殖支原体和莱氏无胆甾原体的混合菌。在34份血清中，有13份显示出针对莱氏无胆甾原体的抗体证据。
