Mycobacterium chelonei iatrogenic infections

Area of Science:

• Microbiology
• Infectious Diseases
• Dermatology

Background:

• Cutaneous infections can arise from contaminated medical supplies.
• Mycobacterium chelonei subsp. abscessus is an opportunistic pathogen.
• Surgical site infections pose a significant risk to patient outcomes.

Purpose of the Study:

• To investigate the cause of two outbreaks of cutaneous infections.
• To identify the source of Mycobacterium chelonei subsp. abscessus transmission.
• To report on infections following venous stripping procedures.

Main Methods:

• Bacteriological study of 15 patients.
• Epidemiological investigation of infection outbreaks.
• Analysis of presurgical antiseptic solutions.

Main Results:

• Two outbreaks of Mycobacterium chelonei subsp. abscessus infections were identified.
• Infections occurred in patients undergoing venous stripping for varicose veins.
• The merbromin solution used for presurgical care was identified as the source.

Conclusions:

• Contaminated merbromin solutions can lead to Mycobacterium chelonei subsp. abscessus outbreaks.
• Strict quality control of antiseptic solutions is crucial.
• Preventing surgical site infections requires vigilant monitoring of medical supplies.
