Four pony mares were readily infected with the organism of contagious equine metritis by intracervical inoculation and one by coitus with an infected stallion. Infected mares developed an acute endometritis with local destruction of the endometrial epithelium. In 2 experimentally infected mares, infection appeared to have been spontaneously eliminated from the genital tract within 3 to 4 weeks. A third mare however remained persistently infected in the clitoral fossa over a long period and was a symptomless carrier. Four pony stallions were readily infected in the urethral fossa and the organism survived for varying periods without giving rise to any signs of infection. From 2 of these animals it appeared eventually to have been eliminated spontaneously. An experimentally infected stallion transmitted infection to a healthy mare by coitus. Bacteriological examination of infected pony stallions may occassionally give false negative results and fail to reveal the organism in the external genitalia. Repeated bacteriological examinations need to be undertaken before it can be concluded that a stallion is free of infection.
四匹小母马经子宫颈接种很容易感染马传染性子宫炎病原体，一匹通过与感染的种马交配而感染。感染的母马发生急性子宫内膜炎，子宫内膜上皮局部遭到破坏。在2匹实验感染的母马中，感染似乎在3至4周内从生殖道自行消除。然而，第三匹母马在很长一段时间内阴蒂窝持续感染，是无症状携带者。四匹小种马在尿道窝很容易感染，病原体存活了不同时间而未出现任何感染迹象。其中2匹马的病原体最终似乎自行消除。一匹实验感染的种马通过交配将感染传播给一匹健康母马。对感染的小种马进行细菌学检查偶尔可能得出假阴性结果，无法在外生殖器中发现病原体。在得出种马没有感染的结论之前，需要进行反复的细菌学检查。
