title: Identities of Microbacterium spp. encountered in human clinical specimens.
abstract: In the present study, 50 strains of yellow-pigmented gram-positive rods that had been isolated from human clinical specimens and collected over a 5-year period were further characterized by phenotypic and molecular genetic methods. All 50 strains belonged to the genus Microbacterium, and together they represented 18 different species. Microbacterium oxydans (n = 11), M. paraoxydans (n = 9), and M. foliorum (n = 7) represented more than half of the strains included in the present study. The isolation of strains belonging to M. hydrocarbonoxydans (n = 2), M. esteraromaticum (n = 1), M. oleivorans (n = 1), M. phyllosphaerae (n = 1), and M. thalassium (n = 1) from humans is reported for the first time. Microbacterium sp. strain VKM Ac-1389 (n = 1) and the previously uncultured Microbacterium sp. clone YJQ-29 (n = 1) probably represent new species. Comprehensive antimicrobial susceptibility data are given for the 50 Microbacterium isolates. This study is, so far, the largest on Microbacterium spp. encountered in human clinical specimens and outlines the heterogeneity of clinical Microbacterium strains.
