Bartonella Species
MICROBIOLOGY
- Small fastidious intracellular pleomorphic Gram-negative bacilli.
- Columbia, Brucella, BHI, and Trypticase soy-based agars (all 5% blood supplemented) and chocolate agar are the most frequently used solid media used for Bartonella isolation.
- Bartonella has > 45 known species, and more than seven cause human disease: B. henselae, B. bacilliformis, B. quintana, B. vinsonii, B. grahamii, B. elizabethae and B. koehlerae.
- Evolving nomenclature as subspecies classifications, e.g., Bartonella vinsonii subsp. yucatanensi.
- Best seen with Warthin-Starry silver stain or a Brown-Hopps tissue gram stain.
- The primary reservoir of B. henselae is cats -- 50% of cats are seropositive and transmitted by saliva contact or scratching ("cat scratch fever" or catch scratch disease [CSD]).
- The menu of diseases caused by Bartonella includes cat scratch disease, retinitis, trench fever, Carrión’s disease [Oroyo fever and verruga peruana], relapsing bacteremia, endocarditis, bacillary angiomatosis, and bacillary peliosis hepatitis.
