Rattus rattus, the black rat. Smaller than Rattus norvegicus, the brown rat, which later supplanted it, it is also keener to live near humankind. Timber houses and overcrowded slums provided excellent homes. The link between the rat as reservoir of infection and host to fleas which could transfer to man was not understood. Efforts were made to eliminate cats and dogs: if anything, this encouraged the rats. Body lice were also important plague vectors.

The Oriental rat flea (Xenopsylla cheopis) engorged with blood. This species of flea is the primary vector for the transmission of Yersinia pestis, the organism responsible for spreading bubonic plague in most plague epidemics. Both male and female fleas feed on blood and can transmit the infection.

Oriental rat flea (Xenopsylla cheopis) infected with the Yersinia pestis bacterium which appears as a dark mass in the gut. The foregut (proventriculus) of this flea is blocked by a Y. pestis biofilm; when the flea feeds on an uninfected host Y. pestis is regurgitated into the wound, causing infection.

Skeletons in a mass grave from 1720 to 1721 in Martigues, near Marseille in southern France, yielded molecular evidence of the orientalis strain of Yersinia pestis, the organism responsible for bubonic plague. The second pandemic of bubonic plague was active in Europe from 1347, the beginning of the Black Death, until 1750.
