Type strains of 72 validated Nocardia species were phylogenetically analyzed based on the multilocus sequence analysis (MLSA) concatenated atpD-groL1-groL2-recA-rpoA-secY-sodA-ychF. Furthermore, their similarity based on digital DNA-DNA hybridization (dDDH) was calculated. Nocardia soli, Nocardia cummidelens and Nocardia salmonicida, Nocardia nova and Nocardia elegans, Nocardia exalbida and Nocardia gamkensis, and Nocardia coubleae and Nocardia ignorata formed coherent clades, respectively.

Following recent advances in medical technology, the increased number of immunocompromised patients such as those with organ transplants has led to an increase in opportunistic infections due to Nocardia. Although nocardiosis has been considered to be rare, recent reports indicate that the incidence of the infection is increasing. The Nocardia asteroides group is the principal source of infectious species, but the definition of species in Nocardia is problematic because species identification of N.

The type strain of Nocardia corynebacterioides was the subject of a polyphasic taxonomic study. The 16S rRNA gene sequence was aligned with the sequences of representatives of the genera Corynebacterium, Dietzia, Gordonia, Mycobacterium, Nocardia, Rhodococcus, Skermania, Tsukamurella and Williamsia, and phylogenetic trees were constructed by using maximum-parsimony, maximum-likelihood and neighbour-joining methods. It was evident from the phylogenetic analysis that N.

The current systematics of the genus Rhodococcus is unclear, partly because many members were originally included before the application of a polyphasic taxonomic approach, central to which is the acquisition of 16S rRNA sequence data. This has resulted in the reclassification and description of many new species. Hence, the literature is replete with new species names that have not been brought together in an organized and easily interpreted form.
