Table_2_Brucella suis biovar 1 infection in a dog with orchitis in Germany.xlsx

In 2021, a case of canine brucellosis diagnosed in a dog with orchitis was presented to a veterinary practice in Germany. Serological testing excluded Brucella (B.) canis as a causative agent, but molecular analysis revealed the presence of B. suis biovar 1. Since biovar 1 is not endemic in Europe and the dog had no history of travel to endemic areas, a comprehensive epidemiological investigation was conducted using whole genome sequence data to determine the source of infection. We describe the clinical progress of the animal and the potential infection of a veterinary clinic employee. The findings highlight the importance of considering less common Brucella species as possible causes of canine brucellosis. The data also emphasize that it is quite challenging to identify Brucella species in a routine diagnostic laboratory and to conduct epidemiological investigations to unveil possible transmission routes.

2021年，德国一家兽医诊所报告了一例患有睾丸炎的犬类布鲁氏菌病病例。血清学检测排除了布鲁氏菌（B. canis）作为致病因素，但分子分析揭示了猪布鲁氏菌（B. suis）生物型1的存在。鉴于生物型1在欧洲并非地方性流行，且该犬无前往地方性流行地区的旅行史，因此，我们利用全基因组序列数据进行了全面的流行病学调查，以确定感染源。本文描述了动物的病程进展及兽医诊所员工潜在的感染情况。研究结果强调了在考虑犬类布鲁氏菌病的可能病因时，应考虑较少见的布鲁氏菌属物种。此外，数据还突显了在日常诊断实验室中识别布鲁氏菌属物种以及开展流行病学调查以揭示可能的传播途径的巨大挑战。
