And maybe for those living in areas where Y. pestis is endemic, reconsider whether approaching or eating cute rodents is a good idea.

However, until I read a recent PLoS ONE article, I did not realize there was still debate about whether Yersinia pestis was the infectious agent for Black Death, the disease that ravaged 14th century Europe and killed one third of its population.
