Perspectives on Yersinia pestis: A Model for Studying Zoonotic Pathogens

Yersinia pestis is a typical zoonotic bacterial pathogen. The following reasons make this pathogen a model for studying zoonotic pathogens: (1) Its unique lifestyle makes Y. pestis an ideal model for studying host-vector-environment-pathogen interactions; (2) population diversity characters in Y. pestis render it a model species for studying monomorphic bacterial evolution; (3) the pathogenic features of bacteria provide us with good opportunities to study human immune responses; (4) typical animal and vector models of Y. pestis infection create opportunities for experimental studies on pathogenesis and evolution; and (5) repeated pandemics and local outbreaks provide us with clues about the infectious disease outbreaks that have occurred in human history.
