Catheter-related bacteremia due to Mycobacterium smegmatis
1University of Texas Southwestern Medical Center, Dallas 75235-9113, USA.
Abstract:
Rapidly growing mycobacteria have occasionally been reported to cause catheter-related infections. We report a case of a central venous catheter-related bacteremia, caused by Mycobacterium smegmatis, in a patient with cancer. Cultures of the catheter tip and blood cultures grew M smegmatis and Enterococcus faecalis. The patient responded to catheter removal and a 3-month course of antibiotics (doxycycline and ciprofloxacin). Based on our experience and the reported experience with other rapidly growing mycobacteria, M smegmatis catheter-related bacteremia should be treated with catheter removal and a course of appropriate antibiotics, based on in vitro susceptibility testing.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
