ABSTRACT
Organisms of the Mycobacterium fortuitum complex are recognized, but uncommon, causes of pulmonary disease, primary cutaneous disease and a wide spectrum of nosocomial infections. M.fortuitum was isolated from 20 patients over a 15-month period, with an apparent clustering of isolates of M.fortuitum occurring from January to March 1994. The molecular epidemiology of this clustering was investigated using an arbitrary primer-polymerase chain reaction method (AP-PCR). Twenty-two isolates were studied and yielded 14 distinct profiles. Multiple isolates from a single patient yielded identical profiles. All of seven isolates of M.fortuitum recovered during the six-weeks period from January to March 1994 shared a common profile which was distinct from all other isolates, suggesting that a single strain was located from specimens from all seven patients. The source of the cluster of isolates of M.fortuitum is uncertain. We can find no epidemiological link upon which to suppose an episode of cross-infection within the hospital environment. Therefore it seems likely that contamination of the specimens during collection, transport or processing was responsible for the "pseudo-outbreak" of M.fortuitum observed in this study (AU)
