Host-Specialization Of Bartonella In Flea Vectors Collected From Black-Tailed Prairie Dogs, Mark D. Massaro

Honors Theses

At least 22 species of Bartonella bacteria have been named and many are associated with one of a list of potential mammalian reservoirs and arthropod vectors. One example of such a system is the parasitism of black-tailed prairie dogs (Cynomys ludovicianus) of the Western U.S. by Oropyslla hirsuta and Pulex simulans fleas. These vectors are thought to maintain B. washoensis infection in these mammals, but little is known about their role in the specialization of this strain to this reservoir. We found that the more specialist O. hirsuta fleas were much more likely to be infected with B. washoensis than …
