Glutathione Metabolism in Y. pseudotuberculosis

This image is a scaled-down version of the actual pathway image. It does not contain any links to the protein information pages.


Yersinia sp. is responsible for disease syndromes ranging from gastroenteritis to plague. Y. pestis is categorized into three subtypes or biovars; Antiqua, Mediaevalis, and Orientalis, each associated with a major pandemic. Yersinia pseudotuberculosis is the least common of the three main Yersinia species to cause infections in humans. It is primarily a zoonotic infection with variable hosts, including domestic and sylvatic animals. The condition has been associated with food-borne infection, including a few outbreaks. The organism primarily leads to a gastroenteritis (diarrheal component uncharacteristic) characterized by a self-limited mesenteric lymphadenitis mimicking appendicitis. Postinfectious complications include erythema nodosum and reactive arthritis. Thus, a major triad for infection with this organism includes fever, abdominal pain, and rash. Rarely, it has been associated [...]
