biovar 1 infection in a dog with orchitis in Germany.

Abstract

In 2021, a case of canine brucellosis diagnosed in a dog with orchitis was presented to a veterinary practice in Germany. Serological testing excluded(.)as a causative agent, but molecular analysis revealed the presence ofbiovar 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 commonspecies as possible causes of canine brucellosis. The data also emphasize that it is quite challenging to identifyspecies in a routine diagnostic laboratory and to conduct epidemiological investigations to unveil possible transmission routes.
