title: Lysogeny associated with mucoid variation in Mycobacterium kansasii.
abstract: Ten of 200 strains of Mycobacterium kansasii were found to produce very mucoid growth on Löwenstein-Jensen medium. By electronmicroscopy these 10 strains were found to be lysogenic, whereas no phage was observed in cultures of 30 non-mucoid strains. The cultural and biochemical properties of the lysogenic strains are compared with those of non-lysogenic strains, and the morphology of the phages is described.
