Abstract

In July 2018, brucellosis was diagnosed in a German patient without a travel history to regions endemic for Brucella. Microbiological analysis, including whole-genome sequencing, revealed Brucella suis biovar 1 as the etiologic agent. Core-genome-based multilocus sequence-typing analysis placed the isolate in close proximity to strains originating from Argentina. Notably, despite a strong IgM response, the patient did not develop Brucella-specific IgG antibodies during infection. Here, we describe the clinical course of infection, the extensive epidemiological investigations, and discuss possible routes of transmission.
