The interrelationship between the various bacteria isolated from the genital tract of rams and their host animals was studied. The pathogenicity of the different isolates varied. Several of these bacteria could be cultured in a medium consisting of a suspension of pen floor debris solidified with agar, while many organisms survived in the suspension for 10 days. Epidemiological investigations showed that rams kept under intensive systems were subjected to large-scale invasion of their genitalia by bacteria which led to infection of the accessory glands and orchitis and epididymitis. Apart from the preputial cavity, some rams kept on open range were entirely free of bacterial infection of their genitalia, and those that did have bacteria in the deeper parts of their genitalia had a very significantly lower incidence of pathological lesions of their genitalia. Finding bacteria and neutrophils in semen is consistent with the epidemiological findings.
对从公羊生殖道分离出的各种细菌与其宿主动物之间的相互关系进行了研究。不同分离株的致病性各不相同。其中几种细菌可在由用琼脂固化的笔底残渣悬浮液组成的培养基中培养，而许多微生物在悬浮液中存活了10天。流行病学调查表明，集约化饲养的公羊其生殖器受到细菌的大规模侵袭，导致副性腺感染以及睾丸炎和附睾炎。除包皮腔外，一些在野外放养的公羊其生殖器完全没有细菌感染，而那些在生殖器深部确实有细菌的公羊，其生殖器病理损伤的发生率非常显著地较低。精液中发现细菌和中性粒细胞与流行病学研究结果一致。
