Septicemic plague; Other names: Septicaemic plague: Septicemic plague resulting in necrosis: Specialty: Infectious diseases : Symptoms: DIC (disseminated intravascular coagulation) which causes : tissue death due to lack of circulation/perfusion to that tissue, bleeding into the skin and other organs, which can cause red and/or black patchy rash and hemoptysis/hermatemesis
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.

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]
They are caused by Yersinia pestis bacteria spreading from flea bites through the bloodstream to the lymph nodes, where the bacteria replicate, causing the nodes to swell. [3] Plague buboes may turn black and necrotic , rotting away the surrounding tissue, or they may rupture, discharging large amounts of pus . [ 3 ]
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 ]
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.
A number of epidemiologists from the 1980s to the 2000s challenged the traditional view that the Black Death was caused by plague based on the type and spread of the disease. The confirmation in 2010 and 2011 that Yersinia pestis DNA was associated with a large number of plague sites has led researchers to conclude that "Finally, plague is ...
