Abstract
Members of the genus <i>Brucella</i> cluster in two phylogenetic groups: classical and non-classical species. The former group is composed of <i>Brucella</i> species that cause disease in mammals, including humans. A <i>Brucella</i> species, labeled as <i>Brucella</i> sp. BCCN84.3, was isolated from the testes of a Saint Bernard dog suffering orchiepididymitis, in Costa Rica. Following standard microbiological methods, the bacterium was first defined as "<i>Brucella melitensis</i> biovar 2." Further molecular typing, identified the strain as an atypical "<i>Brucella suis</i>." Distinctive <i>Brucella</i> sp. BCCN84.3 markers, absent in other <i>Brucella</i> species and strains, were revealed by fatty acid methyl ester analysis, high resolution melting PCR and <i>omp25</i> and <i>omp2a/omp2b</i> gene diversity. Analysis of multiple loci variable number of tandem repeats and whole genome sequencing demonstrated that this isolate was different from the currently described <i>Brucella</i> species. The smooth <i>Brucella</i> sp. BCCN84.3 clusters together with the classical <i>Brucella</i> clade and displays all the genes required for virulence. <i>Brucella</i> sp. BCCN84.3 is a <i>species nova</i> taxonomical entity displaying pathogenicity; therefore, relevant for differential diagnoses in the context of brucellosis. Considering the debate on the <i>Brucella</i> species concept, there is a need to describe the extant taxonomical entities of these pathogens in order to understand the dispersion and evolution.
