Outbreak of Nontuberculous Mycobacterial Subcutaneous Infections Related to Multiple Mesotherapy Injections

Abstract

We describe an outbreak of severe subcutaneous infections due to nontuberculous mycobacteria following mesotherapy. Epidemiological studies and molecular comparisons of Mycobacterium chelonae strains from different patients and the environment suggested that contamination may be associated with inappropriate cleaning of the multiple-injection device with tap water.
