Bartonella species are vector-transmitted, blood-borne, intracellular, gram-negative bacteria that can induce prolonged infections in the host.
A wide spectrum of diseases can be attributed to Bartonella infections in both immunocompetent as well as immunocompromised individuals. There are several species capable of causing infections in humans, especially Bartonella henselae and Bartonella quintana. Persistent infections of humans and animals (domestic and wild) result in a substantial reservoir of Bartonella organisms in nature, which can serve as a source for inadvertent infection of humans.
