title: Comparative studies of the strains PA and PN of Mycobacterium phlei leading to their reclassification: examination of lipids and DNA, biochemical tests and phage typing.
abstract: Study of lipid and DNA, biochemical tests and phage typing performed on the strain PA previously labelled Mycobacterium phlei, lead to the conclusion that this strain belongs to the species M. smegmatis. Parallel studies performed on strain PN, isolated from a culture of strain PA, as well as DNA homology percentage of the two strains, do not support the assumption that strain PN could have resulted from a mutation of strain PA Strain PN produces mycolic acids similar to those found in Rhodococcus bronchialis; the few biological tests applied quite agree with such a classification.
