Abstract

Mycobacterium genavense, first identified in 1990, is known as a pathogen that mimics disseminated Myocobacterium avium-intracellulare complex (MAC) infection with particular propensity for the gastrointestinal tract. In Korea, no case with the organism has been reported. Herein we report a case of Mycobacterium genavense infection that manifested with erosive lesion of duodenum in a patient with acquired immune deficiency syndrome. The patient presented with epigastric pain and fever, diarrhea. Duodenal biopsy showed histiocytic infiltration with numerous acid-fast bacilli. Identification of the mycobacterial isolate by the polymerase chain reaction restriction analysis of 16S rRNA gene revealed Mycobacterium genavense.
