Background: Brucellosis is veterinary and human health problem. Methods: A 13-year-old wild caught multiparous and an 8-year-old colony-born nulliparous baboon had stillbirths in the second trimester of pregnancy. Culture isolates from both postpartum uteruses were characterized using traditional biochemical analysis, PCR, and multilocus sequencing. Results: The isolates morphologically resembled Brucella although their phenotypic characteristics were not consistent with any currently described species. The isolates represent a novel lineage within the genus with unique alleles, not previously seen in surveys of greater than 300 isolates representing the known diversity of the genus, present at 5/9 loci examined. Conclusions: The described cases are to the best of our knowledge the first presentation of a naturally acquired Brucella infection in non-human primates associated with stillbirths from the same colony where Brucella seropositivity in the baboons was described 45 years ago. The organism appears to represent a previously undescribed Brucella species.
