Bartonella species cause serious human infections globally,including bacillary angiomatosis, Oroya fever, trench fever,and endocarditis. We describe a patient who had fever and splenomegalyafter traveling to Peru and also had bacteremia from an organismthat resembled Bartonella bacilliformis, the causative agentof Oroya fever, which is endemic to Peru. However, genetic analysesrevealed that this fastidious bacterium represented a previouslyuncultured and unnamed bartonella species, closely related toB. clarridgeiae and more distantly related to B. bacilliformis.We characterized this isolate, including its ability to causefever and sustained bacteremia in a rhesus macaque. The routeof infection and burden of human disease associated with thisnewly described pathogen are currently unknown.
