DNA enterobacterial repetitive intergenic consensus PCR (eric) analysis of rapidly growing mycobacteria isolated from 3 patients in a mesotherapy-associated outbreak, January–February, 2007, Buenos Aires city, Argentina, compared with profiles of epidemiologically unrelated clinical isolates of the Mycobacterium abscessus–M. chelonae group. The dendrogram was constructed with the aid of BioNumerics software v 4.6 (Applied Maths, Sint-Martens-Latem, Belgium), using Dice unweighted pair group method coefficients with 1% tolerance. PRA, PCR-restriction analysis of the hsp65 gene.
