Pestis

In ancient and medieval times, people thought the plague was caused by rats, but the true cause wasn't discovered until 1894, when Alexandre Yersin of France and Kitasato Shibasaburo of Japan finally traced it to a bacterium now called Yersinia pestis, which is transmitted by fleas, which in turn are carried around by rats. ❋ Steven Salzberg (2011)

Another plague that really made the “dark” Middle Ages dark was the Black Death, or bubonic plague, which is caused by the bacterium Yersinia Pasteurella pestis. ❋ Ben Hobrink (2011)

* It was widely caused by a bacterium named Yersinia pestis and was spread by rats and fleas. ❋ Unknown (2009)

In addition to mosquitoes, today I might add Plasmodium falciparum, Vibrio cholerae, and Yersinia pestis to the list (the life forms responsible for malaria, cholera, and the Black Death respectively). ❋ Unknown (2010)

The Black Death of the Middle Ages is traditionally considered to have been an outbreak of the bubonic plague, a disease caused by the bacterium Yersinia pestis, the disease spread by fleas carried by animals, especially by the black rat. ❋ Unknown (2009)

In 1347, the bacterium Yersinia pestis, carried by rats and spread by fleas, caused the "Black Death" -- an outbreak of bubonic plague. ❋ Unknown (2009)

I have no knowledge of the rat population in Iceland, but in regards to the spread of disease with the plague - it is the same bacterium Yersinia pestis that is the causative agent. ❋ Unknown (2008)

Fleas become infected by feeding on rodents, such as the chipmunks, prairie dogs, ground squirrels, mice, and other mammals that are infected with the bacteria Yersinia pestis. ❋ Unknown (2008)

Jackson and Plano (2000) report that the Yersinia pestis FliH homolog YscL (corresponding to SctL/HrpE in Figure 4a) has low but significant sequence similarity with the e subunit of the archaeal ATPase of Methanococcus jannaschii and the e subunit of the vacuolar ATPase of Desulfurococcus spp.; these subunits are the homologs of the b subunit of the F1F0-ATP synthetase. ❋ Unknown (2006)

In the study, scientists genetically modified tobacco mosaic virus (TMV) with genes from Yersinia pestis, the bacteria that causes plague. ❋ Nick Anthis (2006)

After guinea pigs were exposed to Yersinia pestis, all untreated animals died, but 38 to 75% of vaccinated animals survived, depending on the specific vaccine used. ❋ Nick Anthis (2006)

Borne by fleas that circulate among rodents, Y. pestis can infect humans with bubonic plague, causing fever, headache and painful swelling of the lymph nodes. ❋ Unknown (2008)

The same bacterium, Yersinia pestis, is responsible for both pneumonic and bubonic plague. ❋ Unknown (2008)

Centers for Disease Control and PreventionPlague is an infectious disease of animals and humans caused by a bacterium named Yersinia pestis. ❋ Unknown (2008)

By fleas that become infected with bacteria Yersinia pestis that cause plague. ❋ Unknown (2008)
