mycobacterium (M. tb) could be a
species of morbific
microorganism within the bacteria family and therefore the motivating agent of T.B.. initial discovered in 1882 by Koch, M. T.B. has associate degree uncommon, waxy coating on its cell surface primarily because of the presence of mycolic acid. This coating makes the
cells proof to Gram staining, and as a result, M. T.B. will seem either gram-negative or gram-positive. impervious stains like Ziehl-Neelsen, or fluorescent stains like auramine square measure used instead to spot M. T.B. with a magnifier. The
physiology of M. T.B. is extremely aerobic and needs high levels of O. Primarily a infective agent of the class systema respiratorium, it infects the lungs. the foremost oftentimes used diagnostic ways for T.B. square measure the liquid diagnostic assay, impervious stain, culture, and enzyme chain reaction. The M. T.B. ordering was sequenced in 1998. alternative
microorganism square measure usually known with a magnifier by staining them with staining. However, the mycolic acid within the cytomembrane of M. T.B. doesn't absorb the stain. Instead, impervious stains like Ziehl-Neelsen stain, or fluorescent stains like auramine square measure used.
Cells square measure curvilinear rod-shaped and square measure typically seen wrapped along, because of the presence of fatty acids within the cytomembrane that rest. This look is observed as cording, like strands of wire that conjure a rope. M. T.B. is characterised in tissue by caseating granulomas containing Langhans large cells, that have a "horseshoe" pattern of nuclei.
