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 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.
Bubonic plague is one of three types of plague caused by the bacterium Yersinia pestis. [1] One to seven days after exposure to the bacteria, flu-like symptoms develop. [1] These symptoms include fever, headaches, and vomiting, [1] as well as swollen and painful lymph nodes occurring in the area closest to where the bacteria entered the skin. [2]
Caused by the bacterium Yersinia pestis and primarily spread by fleas on rats, the plague also swept through Asia and North Africa. It resulted in the deaths of an estimated 25 million to 30 ...
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]
A study published Tuesday in PLOS Biology suggests that body lice may be more efficient at transmitting the plague bacteria, Yersinia pestis, than previously thought and thus might have helped ...
The disease is caused by the bacterium Yersinia pestis and spread by fleas and through the air. [4] [5] One of the most significant events in European history, the Black Death had far-reaching population, economic, and cultural impacts. It was the beginning of the second plague pandemic. [6]
