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.
As the disease progresses, the lymph nodes can hemorrhage and become swollen and necrotic. Bubonic plague can progress to lethal septicemic plague in some cases.

Although it has been defined as an extension of pneumoconiosis, there is no scientific evidence for a similar disease related to volcanic silica particle exposures. [8] Subsequently, the word was used in Frank Scully's puzzle book Bedside Manna, after which time, members of the N.P.L. campaigned to include the word in major dictionaries. [9] [10]
The armadillo became the only known animal other than primates to regularly develop leprosy and has since largely advanced the disease study through use of in vivo propagation of M. leprae. Dasypus was also an ideal model due to the ability to replicate experiments on their genetically identical siblings.
