An outbreak of bovine tuberculosis on a dairy farm is described. Following intradermal tuberculination 84 animals out of 111 animals older than 6 weeks had a positive reaction. Of the 34 adult sheep one gave a positive reaction. All animals on the farm were taken over for destruction by the Animal Health Centre. The source of the infection could not be established although there was a strong suspicion that the importation of three older dairy cows had introduced the infection on the farm. A further investigation was done on 45 farms. Two of these farms were infected by buying animals from the dairy farm in question. During the investigations the possible transmission of the infections to people who were in close contact to the infected animals was also investigated. From 35 examined persons 5 had a positive Mantoux-reaction. The outbreak coincided with a political discussion concerning the abolishment of the periodical tuberculination on dairy farms. Since 1 January 1993 the surveillance of bovine tuberculosis in the Netherlands is done by import control and findings in slaughter-houses combined with a good identification system. It is stressed that the examinations of the lymph glands in the slaughter-houses require the necessary attention.
描述了一个奶牛场爆发牛结核病的情况。在对111头6周龄以上的动物进行皮内结核菌素试验后，有84头呈阳性反应。34只成年绵羊中有1只呈阳性反应。动物卫生中心接管了该农场的所有动物并予以销毁。尽管强烈怀疑引进的3头成年奶牛将感染带入了农场，但感染源仍无法确定。对45个农场进行了进一步调查。其中有两个农场因从该奶牛场购买动物而受到感染。在调查过程中，还对与感染动物密切接触的人员可能感染的情况进行了调查。在35名接受检查的人员中，有5人结核菌素试验呈阳性反应。此次疫情爆发恰逢一场关于取消奶牛场定期结核菌素试验的政治讨论。自1993年1月1日起，荷兰通过进口控制、屠宰场的检查结果以及完善的识别系统对牛结核病进行监测。强调屠宰场对淋巴结的检查需要给予必要的关注。
