Yersinia arthritis

Yersinia arthritis

Etymology: Alexandre E.J. Yersin
a polyarticular inflammation occurring a few days to 1 month after the onset of infection caused by Yersinia enterocolitica or Y. pseudotuberculosis and usually persisting longer than 1 month. Knees, ankles, toes, fingers, and wrists are most often affected. Cultures of synovial fluid yield no infectious organism. The clinical presentation may mimic juvenile rheumatoid arthritis, rheumatic fever, or Reiter's syndrome and may be associated with erythema nodosum or erythema multiforme. Treatment is with antibiotics.
