Chromobacterium violaceum: An uncommon source of urinary tract infection – A case study with review of literature

Abstract

Chromobacterium violaceum is a Gram-negative bacterium, which is an environmental pathogen causing fatal opportunistic infection in tropical and subtropical areas. This facultative anaerobe produces small colonies with dark violet metallic pigmentation due to the pigment ‘Violacein’, hence the organism derives its name. We report an uncomplicated urinary tract infection by this rare but fatal pathogen in a young immunocompetent female, who fortunately recovered completely with oral antibiotic therapy.
