There has been considerable debate about the nature of the Black Death. Was it due only to the plague bacillus, Yersinia pestis, to this and other conditions such as overwhelming streptococcal and/or staphylococcal infections that coexisted, or could it have been due to anthrax? There are reliable clinical descriptions, though there is much folklore from which inferences can be made. The ecology of plague is complex: Yersinia pestis may be transmitted by direct contact or a droplet spread from infected to susceptible persons, but Bubonic Plague typically is a zoonosis, a disease of rodents, especially rats, transmitted by the rat flea. It spreads from rats to humans in rat-infested dwellings. There is good historical evidence on the prevalence in those days of black rats, Rattus rattus, which prefer indoor habitat and nesting sites close to where people live. Over the next one hundred to two hundred years, black rats were supplanted by brown rats, Rattus norvegicus, whose preferred habitat is outdoors, removing them and their fleas to a slightly safer distance from people.
