Xenopsylla

Xenopsylla
The rat flea; a genus of fleas parasitic on the rat and involved in the transmission of bubonic plague. The species X. cheopis serves as a potent vector of Yersinia pestis, largely because its gut becomes “blocked” by a mass of Y. pestis cells that prevents the flea from feeding normally, so that it is inclined to attack humans and other hosts; it is an important source of infection in traditional epidemic areas such as India. X. astia and X. braziliensis are also efficient vectors of plague. [xeno- + G. psylla, flea]
