Long-term medical management with antibiotics was ...It is caused by either Bartonella henselae or B. quintana. B. henselae is most often transmitted through a cat scratch or bite, though ticks and fleas may also act as vectors. B. quintana is usually transmitted by lice. It can manifest in people with AIDS and rarely appears in those who are immunocompetent. [citation needed] DiagnosisAbstract. Molecular methods can enable rapid identification of Bartonella spp. infections, which are difficult to diagnose by using culture or serology.
