Nocardia mexicana sp. nov., a new pathogen isolated from human mycetomas.
نویسندگان
چکیده
Three isolates collected from human mycetomas and showing an unusual brownish purple pigmentation on Bennett agar plates were analyzed by a polyphasic taxonomic approach, including morphological, biochemical, physiological, and chemotaxonomic properties coupled with genomic and phylogenetic analysis. It clearly appeared that these microorganisms were distinct from their closest phenotypic and genetic match, the most related species according to 16S rRNA gene sequence analysis being Nocardia pseudobrasiliensis. The data obtained indicated that the three clinical strains should be recognized as a new species for which the name Nocardia mexicana sp. nov. is proposed.

A novel actinomycete strain YIM 33361(T) was isolated from a soil sample collected from Yunnan, China. Comparative 16S rRNA gene sequencing showed that the strain constituted a distinct subclade within the genus Nocardia, displaying more than 3% sequence divergence from established species. Based on its morphological, chemotaxonomic, phenotypic and genotypic characteristics, strain YIM 33361(T)...

Previously Neoidiotypa was a monotypic genus represented by a peculiar wasp-like richardiid from Cuba - N. appendiculata (Loew). In this work, five new species are described in this genus: N. mexicana sp. nov. from Mexico; N. alamagna sp. nov., N. flaviatra sp. nov., N. nigra sp. nov. and N. sticta sp. nov. from Costa Rica. New diagnostic characters for the genus are included. An identification...
