What's eating you? oriental rat flea (Xenopsylla cheopis).

The oriental rat flea (Xenopsylla cheopis) is an ectoparasite of small mammals and a vector of many diseases for which humans are incidental hosts. This species of flea is most widely known for carrying Yersinia pestis and Rickettsia typhi, the causative agents of the plague and murine typhus, respectively. Public health issues related to X cheopis may increase in the future as global warming expands the geographic area in which the fleas can survive. A bioterrorist attack of plague also remains a threat. Extensive research is ongoing regarding X cheopis and its interaction with the bacteria it transmits to find better ways of reducing related morbidity and mortality. Traditional control measures include extermination of small mammal hosts, insecticide use to eliminate the flea itself, and use of antibiotics to control the associated diseases. The future may include targeted insecticide usage to prevent the continued development of resistance as well as new methods of reducing transmission of flea-borne diseases that could eliminate the need for chemical insecticides all together.
