title: Acute synovitis caused by an organism of the Rhodochrous taxon.
abstract: A 36-year-old man with systemic lupus erythematosus developed synovitis of the right wrist caused by an organism of the Rhodochrous taxon. The capacity of this pathogen to produce a granulomatous inflammatory reaction in human tissues is discussed. The isolate was sensitive to chloramphenicol, gentamicin, carbenicillin and colistin in in-vitro tests and the infection responded promptly to treatment with chloramphenicol.
