Fleas obviously cause anemias and massive blood loss, but do they serve as vectors as well?
1. Fleas are responsible for transmission of blood filarid A. reconditum, often confused with microfilaria of D. immitus.
2. Fleas, the inoculation of flea feces and saliva in infected nail beds of cats and cat bites are routes of transmission of bacteria B. henselae (and other species) resulting in what is known as Cat Scratch Disease.
