A case of successfully treated relapsing peritoneal dialysis-associated peritonitis caused by Gordonia bronchialis in a farmer.

Gordonia species are aerobic, weakly acid-fast, Gram-positive pathogens that rarely cause human infections, usually in immunocompromised patients. It is uncommon bacilli in cases of peritoneal dialysis-related peritonitis. The small number of infections with Gordonia species reported for humans may be stipulated by the difficulty in identifying the organism using conventional techniques. Careful review of Gram stains and modified-acid-fast stains should be done, so that confusion with other actinomycetes is minimized, pending the genotypic identification. Here we report a case that was caused by Gordonia bronchialis and thus required different considerations of treatment.
