Mycobacterium tuberculosis. Coloured transmission electron micrograph (TEM) of the bacteria,Mycobacterium tuberculosis. This is a Gram- positive rod-shaped bacillus bacterium that causes tuberculosis (TB) in humans. The outer surface of the cell is covered by a complex of proteins,fats & lipids. These surface proteins stimulate an immune response from an infected patient. Mycobacterium tuberculosis is spread by coughing or sneezing,and is inhaled into the lungs. It forms a primary tubercle during initial infection,which develops into pulmonary TB. TB is still a fatal disease. Magnification:x18,500 at 6x4.5cm size | |
