在一次由S.然而，该微生物经常从牛使用的稻草垫料样本中分离出来。超过106个S。从36%的样品中分离出了细菌/g秸秆。从34%的牛粪便样品中也回收到了该微生物，但数量通常很低。对从其他32个奶牛场的牛场收集的秸秆样本的检查表明，这不是一个孤立的事件，因为S。在56%牛群的24%样本中发现了UE 2。未发现S.大肠杆菌和大肠菌群。这些意见的意义进行了讨论。
During an outbreak of mastitis due to S. uberis, the organism was frequently isolated from samples of straw bedding used by the cattle. More than 106 S. uberis/g straw were isolated from 36% of samples. The organism was also recovered from 34% of samples of bovine feces, but usually in low numbers. An examination of straw samples collected from cattle yards on 32 other dairy farms demonstrated that this was not an isolated occurrence since S. uberis was found in 24% of samples from 56% of the herds. No correlation was found between counts of S. uberis and coliforms. The significance of these observations is discussed.
