This 1971 photomicrograph of a sputum smear, which had been stained using the Morse method of fluorescent acid-fast staining technique, revealed the presence of two Mycobacterium tuberculosis, rod-shaped bacteria, otherwise known as bacilli.Created: 1971

Under a high magnification of 15549x, this colorized scanning electron micrograph (SEM) depicted some of the ultrastructural details seen in the cell wall configuration of a number of Gram-positive Mycobacterium tuberculosis bacteria. As an obligate aerobic organism M. tuberculosis can only survive in an environment containing oxygen. This bacterium ranges in length between 2 - 4 microns, and a width between 0.2 - 0.5 microns. See PHIL 8438 for a black and white version of this image.Created: 2006
