Tritrichomonas foetus is a protozoan parasite associated with reproductive failure in the bovine. Its incidence has effectively been controlled in the UK, as in many other countries, through a policy of testing of breeding animals and the widespread use of artificial insemination (AI). As a result there have been only two cases of bovine trichomoniasis in the UK over the past 20 years. Despite the virtual absence of T. foetus in bovine preputial and vaginal samples, routine examinations have occasionally revealed the presence of motile protozoa which require careful identification. In this paper, the morphological characteristics of T. foetus, and other protozoa isolated from the bovine reproductive tract, are presented.
胎儿三毛滴虫是一种与牛繁殖障碍相关的原生动物寄生虫。与许多其他国家一样，通过对种畜进行检测以及广泛使用人工授精（AI）的政策，其在英国的发病率已得到有效控制。因此，在过去20年中，英国仅出现了两例牛毛滴虫病病例。尽管在牛包皮和阴道样本中几乎不存在胎儿三毛滴虫，但常规检查偶尔会发现有活动的原生动物，需要仔细鉴定。本文介绍了胎儿三毛滴虫以及从牛生殖道分离出的其他原生动物的形态特征。
