A turkey-breeding operation in Eastern Europe had been suffering from an infertility problem for about 1 year. During the first visit of the investigation, ureaplasma was isolated from 4 out of 10 toms and 3 out of 5 hens randomly selected from a flock of 250 males and 2,200 females. The candled fertility at the time of investigation was 66%. Twelve weeks later, ureaplasma was isolated from five out of five hens from a flock that had a candled fertility of 51%, whereas no isolations were made from five out of five hens that had a fertility of 94%. Stained preparations of semen were evaluated, demonstrating an increased number of stressed abnormal spermatozoa. Histopathological lesions suggestive of a mycoplasma infection were observed in the oviduct of females. Several tests were conducted for various viral and bacterial infections and for the presence of mycotoxins in the feed; all were negative.
东欧一家火鸡养殖企业遭受不育问题困扰约一年。在调查首次到访时，从一群250只雄火鸡和2200只雌火鸡中随机选取的10只雄火鸡中的4只以及5只雌火鸡中的3只分离出了脲原体。调查时照蛋的受精率为66%。12周后，从一群照蛋受精率为51%的母鸡中，在5只母鸡中的5只分离出了脲原体，而在受精率为94%的5只母鸡中的5只未分离出脲原体。对精液染色涂片进行了评估，结果显示应激异常精子数量增加。在雌性火鸡的输卵管中观察到提示支原体感染的组织病理学病变。针对各种病毒和细菌感染以及饲料中霉菌毒素的存在进行了多项检测；所有检测结果均为阴性。
