title: Mycobacterium chelonei infection of a Broviac catheter insertion site.
abstract: Mycobacterium chelonei infection developed at the insertion site of an indwelling Broviac catheter in a child with erythroleukemia. Direct adherence to and colonization of the intra- and extra-luminal surfaces of the catheter, with extension to the adjacent subcutaneous tissue, by this rapidly growing mycobacterium may have been the primary factor underscoring the infection. Nontuberculous mycobacteria such as Mycobacterium chelonei grow readily on routine bacteriologic media and resemble Corynebacterium spp. (diphtheroids) in their Gram staining and microscopic characteristics. The persistence of the infectious process and a diphtheroid-like microorganism despite antimicrobial therapy should raise the suspicion for a mycobacterial species.
