A zoonotic disease that has killed millions over the course of at least three pandemics, plague remains a threat in regions where the etiologic agent, Yersinia pestis, persists in natural cycles involving small mammals and their fleas. Numerous flea species have been implicated as Y. pestis vectors, and some provide a "bridge" from zoonotic hosts to humans, particularly during the epizootics that decimate susceptible small mammal populations. In order to serve as a bridging vector, a flea species must be able to transmit Y. pestis, it must feed on infectious zoonotic hosts, and it must feed on ...
