Mycobacteria Growth Indicator Tube (MGIT) samples in ultraviolet light. Emission of orange fluorescence indicates the presence of mycobacteria. The samples without fluorescence in this image still reflect some light from the others. Mycobacteria Growth Indicator Tube (MGIT) is intended for the culture, detection and recovery of mycobacteria.
M. tuberculosis in the lungs, showing large cavities the bacteria have dissolved. Mycobacterium tuberculosis (M. tb), also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis.
Micrococcus is a genus of bacteria in the Micrococcaceae family. Micrococcus occurs in a wide range of environments, including water, dust, and soil. Micrococci have Gram-positive spherical cells ranging from about 0.5 to 3 micrometers in diameter and typically appear in tetrads.
Micrococcus spp. are obligate aerobes that inhabit human skin. Staphylococcus spp. also inhabit human skin, but they are facultative anaerobes. They ferment sugars, producing lactic acid as an end product. Many of these species produce carotenoid pigments, which color their colonies yellow or orange. Staphylococcus aureus is a major human ...

An MSA plate with Micrococcus sp. (1), Staphylococcus epidermidis (2) and S. aureus colonies (3). Mannitol salt agar or MSA is a commonly used selective and differential growth medium in microbiology. It encourages the growth of a group of certain bacteria while inhibiting the growth of others. [1]
Kocuria varians is a gram-positive species of bacteria in the genus Kocuria. [4] [5] It has been isolated from milk, [2] [6] meat, [7] skin, soil, [8] and beach sand. [9]It is 0.9 to 1.5 micrometers in diameter, and occurs in clusters, which can be up to 4 millimeters in diameter [8] and are yellow. [9]
Transmission electron micrographs of actively growing (panel A) and nonculturable (panel B) Yersinia pestis.Bar equals 0.5 microns. Viable but nonculturable (VBNC) bacteria refers as to bacteria that are in a state of very low metabolic activity and do not divide, but are alive and have the ability to become culturable once resuscitated.
