B. henselae to people by other arthropods, including wood louse hunter spiders (10), bull ants (20), and tropical rat mites (21), has been suspected on the basis of historical medical findings in conjunction with serological and molecular test results. https://jcm.asm.org/content/53/5/1556
Bartonella species can be directly or indirectly transmitted by an arthropod vector (fleas, keds, lice, sandflies, ticks, and biting flies) (18) among various reservoir-adapted hosts. Although less thoroughly studied, it is likely that many of the same arthropods can directly (bite transmission) or indirectly (contamination of wounds with arthropods' infected feces) transmit Bartonella species to humans. https://jcm.asm.org/content/53/5/1556
