A disease of a wide variety of animal species caused by the bacterium Yersinia pseudotuberculosis. Epizootics of pseudotuberculosis are commonly seen in birds and rodents, often with high case-fatality rates. In humans, seven clinical entities are recognized: primary focalized infections (pseudoappendicitis, acute mesenteric lymphadenitis, or acute terminal ileitis), primary generalized infections (septicemia or scarlatiniform fever), and secondary immunologic phenomena (erythema nodosum or arthralgia).

Three conditions have been called pseudotuberculosis
Infectious disease Human infection by Yersinia pseudotuberculosis which causes acute mesenteric lymphadenitis, mimics acute appendicitis, resulting in abdominal pain and fever
Medspeak An artefact described in a young woman whose braided hair fell into the field of an AP chest film, and thus mimicked the radiologic appearance of tuberculosis
Research A virulent infection of experimental rodents—mice, rats—by Corynebacterium pseudotuberculosis and C kutscheri, causing nonspecific weakness and respiratory distress, possibly progressing to disseminated abscesses or less commonly, granulomas in lungs, kidneys, myocardium, liver, lymph nodes, etc.
