[Yersinia-induced arthritis: new knowledge of pathogenesis, diagnosis and therapy].

Yersinia infections have been identified in rising incidence as the cause of acute or subacute intestinal or extraintestinal diseases in the past two decades. Immunopathological manifestations of Yersinia infections, e.g. Yersinia-induced arthritis, have evoked special interest among clinicians and microbiologists. Beneath epidemiological and clinical characteristics this review focuses on recent progress in pathogenesis and serological and immunohistological diagnosis of Yersiniosis. Possible consequences for newly therapeutical approaches in chronic Yersinia-induced arthritis and spondarthritis were discussed.
