A Case of Severe Septicemia With Chromobacterium violaceum in Bangladesh

Chromobacterium violaceum is a rare but potentially fatal pathogen found in tropical and subtropical regions. Infections with C. violaceum have rarely been reported in humans, with an exceptionally high mortality rate, particularly when linked to septicemia. We report the case of a 45-year-old female farmer from Bangladesh who developed severe septicemia following an insect bite and subsequent self-drainage of an abscess. Blood cultures identified C. violaceum. The patient was treated empirically with intravenous ciprofloxacin and ceftriaxone, leading to full recovery despite resistance to ceftriaxone. Successful management of C. violaceum infections requires early diagnosis and prompt antimicrobial therapy. The intrinsic resistance mechanism of this organism, including the blaCVI gene associated with Carbapenem resistance, necessitates careful antibiotic selection. The literature review highlights successful cases, depending largely on timely intervention. This case highlights the need for careful antibiotic selection based on clinical response and sensitivity patterns. Moreover, increasing awareness among healthcare professionals, particularly in tropical and subtropical regions, is vital for early detection and successful treatment of this rare, life-threatening infection.
