Brucellosis is common worldwide in a variety of animals and is markedly underreported in man. Brucella abortus seems to be decreasing in cattle herds, but new animal reservoirs are being discovered. Human infection presents a difficult diagnostic challenge because of its protean manifestations and multiplicity of organ involvement. Symptoms vary, but fever, chills, weakness and weight loss are common. Several antibiotics are effective.
布鲁氏菌病在全球范围内的多种动物中都很常见，而在人类中的报告明显不足。牛群中的流产布鲁氏菌似乎在减少，但新的动物宿主正在被发现。由于其临床表现多样且累及多个器官，人类感染带来了诊断难题。症状各不相同，但发热、寒战、虚弱和体重减轻很常见。几种抗生素有效。
