Yersiniosis is an infectious disease of the gastrointestinal tract caused by bacteria of the genus Yersinia other than Y. pestis.Most cases of yersiniosis in humans are caused by Y. enterocolitica, with a small minority being caused by Y. pseudotuberculosis.
Yersinia pestis (Y. pestis; formerly Pasteurella pestis) is a gram-negative, non-motile, coccobacillus bacterium without spores that is related to both Yersinia enterocolitica and Yersinia pseudotuberculosis, the pathogen from which Y. pestis evolved [1] [2] and responsible for the Far East scarlet-like fever.
Yersinia enterocolitica is a Gram-negative, rod-shaped bacterium, belonging to the family Yersiniaceae. It is motile at temperatures of 22–29° C (72–84 °F ), but becomes nonmotile at normal human body temperature .
Yersinia is a genus of bacteria in the family Yersiniaceae. [1] Yersinia species are Gram-negative, coccobacilli bacteria, a few micrometers long and fractions of a micrometer in diameter, and are facultative anaerobes. [2] Some members of Yersinia are pathogenic in humans; in particular, Y. pestis is the causative agent of the plague.

2. 1348 – Black Death. The Black Death, one of history’s deadliest pandemics, ravaged Europe from 1347 to 1351. Caused by the bacterium Yersinia pestis and primarily spread by fleas on rats ...
The foregut of this flea is blocked by a Y. pestis biofilm; when the flea attempts to feed on an uninfected host, Y. pestis from the foregut is regurgitated into the wound, causing infection. The bubonic plague is an infection of the lymphatic system, usually resulting from the bite of an infected flea, Xenopsylla cheopis (the Oriental rat flea ...
Pneumonic plague is a severe lung infection caused by the bacterium Yersinia pestis. [3] Symptoms include fever, headache, shortness of breath, chest pain, and coughing. [1] They typically start about three to seven days after exposure. [2] It is one of three forms of plague, the other two being septicemic plague and bubonic plague. [3]
