Much subclinical infection with Brucella abortus affects the dairy farming community, slaughterhouse workers, and veterinary surgeons. High titres of antibody to B. abortus by the saline agglutination, antihuman globulin, or complement fixation test may be shown in subjects from the first two groups and generally there are no symptoms or signs of brucella infection whatever. Veterinary surgeons are prone to subclinical infection and young practitioners frequently display high titres against the usual tests at the same time apparently enjoying good health. Repeated reinfection of this group, however, may result in hypersensitivity to B. abortus and bouts of ill health at intervals may be due to this. Infection seems to come more often from contact with infected material than by drinking untreated milk, particularly in the herdsman, slaughterhouse worker, and veterinary surgeon. A doctor investigating illness of a patient from the dairy farming community and allied occupations should not accept a high titre against B. abortus as the only clue to diagnosis of the patient's condition.
许多布鲁氏菌隐性感染影响着奶牛养殖社区、屠宰场工人和兽医。在前两组人群中，通过盐水凝集试验、抗人球蛋白试验或补体结合试验可能会显示出针对流产布鲁氏菌的高滴度抗体，而且通常无论如何都没有布鲁氏菌感染的症状或体征。兽医容易发生隐性感染，年轻从业者经常在常规检测中显示出高滴度抗体，同时显然身体健康。然而，该群体反复再次感染可能会导致对流产布鲁氏菌过敏，间歇性的健康问题可能由此引起。感染似乎更多是通过接触受感染物质，而非饮用未处理的牛奶，尤其是在牧民、屠宰场工人和兽医中。调查奶牛养殖社区及相关职业患者疾病的医生，不应仅将针对流产布鲁氏菌的高滴度抗体作为诊断患者病情的唯一线索。
