title: The association of Mycobacterium flavum 301 with gram-negative bacteria: ultrastructural and biochemical evidence.
abstract: Morphological characteristics, respiratory quinones, biochemical activities, cell wall ultrastructure and DNA base composition of Mycobacterium flavum 301 were studied. On the basis of the composition of its cell wall, its respiratory quinone and ubiquinone, the organism was associated with gram-negative bacteria. The strain appears to represent a group of bacteria hitherto not described.
