title: [New concept of the taxonomic position of anaerobic corynebacteria].
abstract: The new phenotypic and genotypic characteristics of the anaerobic coryneforms allow us to individualize them in a new sub-genus: Coryneformis nv. sub-gen so defined: Corynebacteriaceae with morphology of true Corynebacterium from which they differ by pathogenicity, the ability to synthesize reticulo-stimulin, their cell-wall composition, thier G + C%, their anaerobic growth and their salmon-pink colonies. They differ also from the true Propionibacterium which are not pathogenic, do not synthesize the reticulo-stimulin, have cream-grey, yellor or red-brown colonies, and do synthesize cobalamine (vitamin B12).
