This paper reviews recent information on the systematics and clinical significance of potentially pathogenic environmental mycobacteria. A short history of these mycobacteria is given. Information on species for which clinical and systematic aspects have already been well documented, i.e., Mycobacterium kansasii, M. marinum, M. scrofulaceum, M. simiae, M. szulgai, M. ulcerans, M. xenopi, and members of the M. fortuitum complex, is updated. Although the M. avium complex was extensively reviewed in earlier literature, major new systematic and clinical information is presented in some detail. Species that have received very limited prior coverage, i.e., M. asiaticum, M. haemophilum, M. malmoense, and M. shimoidei, are the main subjects of this review and are discussed in detail. The rare infections attributed to species that are normally considered nonpathogenic, i.e., M. gastri, M. gordonae, the M. terrae complex, and most of the rapidly growing mycobacteria outside of the M. fortuitum complex, are critically reviewed. Finally, suggestions are offered for practical measures that can minimize the risk of failing to isolate or misidentifying some of the more obscure potentially pathogenic environmental mycobacteria that are only infrequently recognized.

Recent increases in infections caused by Mycobacterium tuberculosis and nontuberculous mycobacteria are a serious hazard to public health (2,6,(11)(12)(13)20). More than 30 mycobacterial species are recognized as pathogenic or potentially pathogenic. Mixed infections with two or more species (1,18,29,31) and nosocomial infections (3,8,19,25,27) are always troublesome. Therefore, timely identification of causative mycobacteria is imperative for appropriate therapy and epidemiological analyses.Genotyping the sequence polymorphisms in the genus Mycobacterium can identify species quickly and unequivocally. PCR-restriction fragment polymorphism analysis (PRA) of the hsp65 gene (4, 21, 22, 28), 16S ribosomal DNA (rDNA) (5, 14, 15, 30), 16S-23S rDNA internal transcribed spacer (ITS) (23), dnaJ (26), rpoB (17), and gyrB (16) has been intensively studied. However, these methods are not applicable for a polymycobacterial sample because too many restriction fragments from multiple species of mycobacteria in it blur the analysis.We developed a fluorescence capillary electrophoresis (FCE)-based restriction fragment-single-strand conformation polymorphism (FCE-RF-SSCP) technique which can simultaneously identify multiple mycobacterial species in a sample. We first established an algorithm for species identification by applying this technique to 110 defined mycobacterial strains.The technique was further validated on "spiked" specimens, clinical sputum specimens, and sputum obtained from a patient with mixed M. avium and M. intracellulare infection.
