Arthritis associated with Salmonella infections.

Infection should always be considered as a possible cause in a patient presenting with arthritis. The diagnosis can be difficult to make because the arthritis may appear without evidence of infection elsewhere, and it may mimic other arthritides. Moreover, aspiration of the joint may only reveal a sterile serous effusion. Many organisms can cause arthritis. One of the rarer causes of such an arthritis is salmonellosis. This paper presents seven cases of arthritis associated with Salmonella infections. Four of the patients were seen by the author and the other three had attended the same hospital in the previous 5 years. Six of the patients were adults.
