A case of Brucella orchitis in a Brahman bull is described. Positive serological titres were detected 1 month before clinical symptoms became obvious, whereas the seminal plasma only contained detectable levels of antibody after the onset of orchitis. It is concluded that serological assays on the seminal plasma alone are inadequate to detect sub-clinically infected animals, and consequently particularly bulls that are intended for use in AI centres should be subjected to a full battery of serological tests as well, before they are certified to be free of brucellosis. The pathology seen in this case was an acute, necrotic orchitis characterized by the presence of numerous granulomas containing the Brucella organisms centrally.
描述了一例婆罗门公牛布鲁氏菌睾丸炎病例。在临床症状明显出现前1个月检测到血清学滴度呈阳性，而精液浆仅在睾丸炎发作后才含有可检测水平的抗体。得出的结论是，仅对精液浆进行血清学检测不足以检测亚临床感染动物，因此，特别是打算用于人工授精中心的公牛，在被认证为无布鲁氏菌病之前，也应进行全套血清学检测。该病例所见病理为急性坏死性睾丸炎，其特征是中央有许多含有布鲁氏菌的肉芽肿。
