6. Mycobacterium tuberculosis Mycobacterium tuberculosis is an obligate pathogenic bacterial
species in the family Mycobacteriaceae and the causative agent
of tuberculosis. M. tuberculosis has an unusual, waxy coating on
its cell surface primarily due to the presence of mycolic acid. Cells
are curved rod-shaped and are often seen wrapped together,
due to the presence of fatty acids in the cell wall that stick
together. This appearance is referred to as cording, like strands
of cord that make up a rope. M. tuberculosis is characterized I
tissue by cadeating granulomas containing Langhans giant cells,
which have a "horseshoe" pattern of nuclei.
