mycobacterium tuberculosis is a species of pathogenic bacteria in the family mycobacteriaceae and the causative agent of tuberculosis. first discovered in 1882 by robert koch, "m. tuberculosis" has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid. this coating makes the cells impervious to gram staining, and as a result, "m. tuberculosis" can appear either gram-negative or gram-positive. acid-fast stains such as ziehl-neelsen, or fluorescent stains such as auramine are used instead to identify "m. tuberculosis" with a microscope. the physiology of "m. tuberculosis" is highly aerobic and requires high levels of oxygen. primarily a pathogen of the mammalian respiratory system, it infects the lungs. the most frequently used diagnostic methods for tuberculosis are the tuberculin skin test, acid-fast stain, culture, and polymerase chain reaction.

mycobacterium tuberculosis complex









































the "mycobacterium tuberculosis" complex (mtc or mtbc) is a genetically related group of "mycobacterium" species that can cause tuberculosis in humans or other animals.









































it includes:









































bullet::::- "mycobacterium tuberculosis"









































bullet::::- "mycobacterium africanum"









































bullet::::- "mycobacterium orygis"









































bullet::::- "mycobacterium bovis and the bacillus calmette–guérin strain"









































bullet::::- "mycobacterium microti"









































bullet::::- "mycobacterium canetti"









































bullet::::- "mycobacterium caprae"









































bullet::::- "mycobacterium pinnipedii"









































bullet::::- "mycobacterium suricattae"









































bullet::::- "mycobacterium mungi"









































in addition, two branches exist which have phylogenetic similarities but are not completely described: the dassie and oryx bacilli. oryx bacilli has been recently reclassified into a separate subspecies, orygis.
