Yersinia
Yersinia
Yersinia (pronunciation: yer-sin-ee-uh) is a genus of bacteria in the family Yersiniaceae.
Etymology
The genus is named after Alexandre Yersin, a Swiss-French physician and bacteriologist, who co-discovered the bacterium responsible for the bubonic plague, which was later named in his honor as Yersinia pestis.
Description
Yersinia species are Gram-negative, rod-shaped bacteria, few micrometers in length and fractions of a micrometer in diameter, and are capable of living in a variety of environments, including soil, water, and animals. Three species are notable for their pathogenicity in humans: Yersinia pestis, Yersinia enterocolitica, and Yersinia pseudotuberculosis.
Yersinia pestis
Yersinia pestis is the causative agent of the plague, a disease that has caused several pandemics throughout history. The bacterium is typically transmitted through the bite of infected fleas that infest rats.
Yersinia enterocolitica
Yersinia enterocolitica is a pathogenic species that can cause yersiniosis, a zoonotic disease that can lead to a range of symptoms, from diarrhea to systemic infections.
Yersinia pseudotuberculosis
Yersinia pseudotuberculosis is a pathogen that can cause Far East scarlet-like fever in humans, and has been responsible for disease outbreaks in animals.
