What are rodents that carried the bubonic plague through Europe in the 1500s?

The rodents that carried the Bubonic Plague through Europe in the 1500s were primarily rats, specifically the black rat (Rattus rattus). These rats were common in urban areas and lived in close proximity to humans, facilitating the spread of the plague. The disease was transmitted to humans through fleas that infested the rats, which carried the bacterium Yersinia pestis. This outbreak of the bubonic plague led to significant social and economic upheaval across Europe.
