在1990至2000年间，韦布里奇兽医实验室的支原体小组从反刍动物中鉴定出1600多种支原体和相关的无毛体。牛支原体是最常见的病原体，主要来自肺炎小牛，但偶尔也来自患有乳房炎和关节炎的牛。犬支原体于1995年在英国首次从患肺炎的牛犊中分离出来，1999年从牛身上分离的支原体数量增加到总支原体的18%。在8959份血清样本中，检测出1971年份牛分枝杆菌抗体阳性(22%)，主要来自肺炎牛。其他已鉴定的支原体包括来自患有呼吸道疾病的牛的肺部的支原体，以及来自患有外阴阴道炎和不孕症的牛的生殖道的牛支原体。牛鼻支原体和沙眼衣原体是常见的，但被认为是更多的机会性而不是致病性。在绵羊和山羊中，分离到的支原体种类主要为肺炎绵羊支原体、绵羊角结膜炎结膜支原体和普遍存在的精氨酸支原体。
Between 1990 and 2000, more than 1600 mycoplasmas and the related acholeplasmas were identified from ruminant animals by the Mycoplasma Group at the Veterinary Laboratories Agency - Weybridge. Mycoplasma bovis was the most commonly identified pathogen, mostly from pneumonic calves but occasionally from cattle with mastitis and arthritis. Mycoplasma canis was first isolated in Britain in 1995 from pneumonic calves and the number of isolates increased to 18 per cent of the total mycoplasmas isolated from cattle in 1999. The ELISA for antibodies to M bovis detected 1971 positive samples (22 per cent) among 8959 serum samples, mainly from pneumonic cattle. other mycoplasmas identified included Mycoplasma dispar from the lungs of cattle with respiratory disease, and Mycoplasma bovigenitalium from the reproductive tract of cows with vulvovaginitis and infertility. Mycoplasma bovirhinis and Acholeplasma species were found commonly but are thought to be more opportunistic than pathogenic. in sheep and goats, the majority of Mycoplasma species isolated were identified as Mycoplasma ovipneumoniae from pneumonic sheep, Mycoplasma conjunctivae from sheep with keratoconjunctivitis, and the ubiquitous Mycoplasma arginini.
