Answer

Healthcare-associated M chelonae infections have been associated with surgical infections of all types, complicating eye, otolaryngologic, chest, abdominal, cardiovascular, reconstructive, cosmetic, and orthopedic procedures. Any intervention involving injectable foreign materials, artificial prostheses, and implantable devices (eg, pacemakers, prosthetic valves) are at risk. [17] Surgical site infections have ranged from sternal wound infections associated with the bone wax to plastic and reconstructive surgical infections linked to contaminated water or marking solution. [18, 19] These infections have been associated with acupuncture and mesotherapy in South America. [20] M chelonae has caused peritonitis and dialysis catheter infections in peritoneal dialysis patients. [21] It causes intravascular catheter infections of all types and is particularly common in the immunocompromised patient.
