Ultrastructure of superficial mycosidic integuments of Mycobacterium sp.

Cells from pellicle growth of Mycobacterium sp. NQ are enveloped in a mycoside layer which extends outward as long filaments, 5 nm in diameter. Underneath this outer mycosidic casement, ramified ropelike structure, embedded in a dense matrix, overlay the rigid peptidoglycan of the cell wall.
