Description
Summary:	Objectives: To summarize the characteristics of and clinical experience with joint infection by group C streptococcus. Methods: Two new cases of acute bacterial arthritis due to group C streptococci are reported, and a MEDLINE search was performed, which located 22 additional cases. Results: Mean age (± standard deviation) of all 24 patients was 46 ± 25 years, and most patients were men (75%). The species most frequently identified was Streptococcus equisimilis (12 cases). Eight patients (33%) had a general risk factor for infection, and the same percentage had some type of arthropathy. Only 3 patients had previous contact with animals. The infection was polyarticular in a third of cases, and the joint most frequently involved was the knee. The majority of patients showed a good response to the treatment with intravenous penicillin. However, 3 patients had functional sequelae, 2 more had residual radiological lesions, and 3 died. Conclusions: Acute bacterial arthritis due to group C streptococci is a serious but uncommon entity that can affect patients without risk factors. Rapid diagnosis and treatment may improve the outcome. Semin Arthritis Rheum 31:43-51. Copyright © 2001 by W.B. Saunders Company
