Bartonella henselae is a fastidious, intracellular, Gram-negative bacterium. Transmission The<unk>  was recognized as the natural reservoir of the<unk>  in 1950 by Robert Debré. Kittens are more likely to carry the bacteria in their blood, so may be more likely to transmit the<unk>  than adult<unk> s. However, fleas serve as a vector for transmission of B. henselae among<unk> s, and viable B. henselae are excreted in the feces of Ctenocephalides felis, the<unk>  flea.<unk> s could be infected with B. henselae through intradermal inoculation using flea feces containing B. henselae. As a consequence, a likely means of transmission of B. henselae from<unk> s to humans may be inoculation with flea feces containing B. henselae through a contaminated<unk><unk>  wound or by<unk>  saliva transmitted in a bite. Ticks can also act as vectors and occasionally transmit the bacteria to humans. Combined clinical and PCR-based research has shown that other organisms can transmit Bartonella, including spiders. Cryptic Bartonella infection may be a much larger problem than previously thought, constituting an unrecognized occupational health hazard of veterinarians.
