<i>Yersinia Enterocolitica</i> In the synovial membrane of patients with <i>Yersinia</i>‐induced Arthritis

Abstract

Using a monospecific rabbit antibody against Yersinia enterocolitica outer membrane protein 1, we examined synovial biopsy specimens from 7 patients with Yersinia-induced arthritis. Yersinia were demonstrated in the synovial membrane by indirect immunofluorescence in 4 patients with Yersinia-induced arthritis, but not in 6 control patients with Salmonella-induced arthritis or with rheumatoid arthritis. These findings suggest the persistence of Yersinia in the joints of patients with Yersinia-induced arthritis.
