Reclassification of Mycobacterium phlei PN-bb as Rhodococcus bronchialis PN-bb

Mycobacterium phlei PN-bb, induced in the parental strain PN by gamma-radiation and ethyl methanesulfonate, should be reclassified as Rhodococcus bronchialis PN-bb. The reclassification is based on the results of lipid analysis, DNA-DNA hybridization and several biochemical tests, performed in comparison with the parental strain PN, earlier reclassified as R. bronchialis, and R, bronchialis (N654).
