Bartonella spp. are gram-negative alphaproteobacteria of the family Bartonellaceae that infect a wide range of animal hosts, including humans (Boulouis et al., 2005). Both fleas and ticks transmit Bartonella spp. although fleas are recognised as the major vector of the key zoonotic Bartonella species, Bartonella henselae (Chomel et al., 2006).

Clinical signs and symptoms of infection vary widely depending on both the specific tissue infected and the immune status of the host. 2 Bartonella henselae is the most common ocular pathogen, although B. quintana, B. grahamii and B. elizabethae infections each have been reported to infect the eye. 3,5,6,7 The natural reservoir of B. henselae ...

Bartonella henselae is well known for causing cat-scratch disease, usually characterized by a mild infection that may be limited to the site of injury, or may present general systemic symptoms such as fever, headache, fatigue, and poor appetite.
