Micrococcus luteus is a Gram-positive to Gram-variable, nonmotile, tetrad-arranging, pigmented, saprotrophic coccus bacterium in the family Micrococcaceae. [1] It is urease and catalase positive. An obligate aerobe , M. luteus is found in soil, dust, water and air, and as part of the normal microbiota of the mammalian skin.
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. They are catalase positive, oxidase positive, indole negative and citrate negative.
Kocuria rosea is a gram-positive bacteria that is catalase-positive and oxidase-positive. It has a coccus shape that occurs in the tetrad arrangement and is a strict aerobe that grows best from 25 to 37 °C. [2] K. rosea has also been found to cause urinary tract infections in people with weakened immune systems. [3]
The catalase test is done by placing a drop of hydrogen peroxide on a microscope slide. An applicator stick is touched to the colony, and the tip is then smeared onto the hydrogen peroxide drop. If the mixture produces bubbles or froth, the organism is said to be 'catalase-positive'. Staphylococci [47] and Micrococci [48] are
The family Micrococcaceae includes bacterial genera of Gram positive cocci that inhabit the air and skin, such as Micrococcus luteus. ... Micrococcus Cohn 1872 ...
Kocuria is a genus of gram-positive bacteria. Kocuria is named after Miloslav Kocur, a Czech microbiologist. It has been found in the milk of water deer and reindeer. [3] Cells are coccoid, resembling Staphylococcus and Micrococcus, and can group in pairs, chains, tetrads, cubical arrangements of eight, or irregular clusters.
From a glance at his background, one might assume that James F. Slattery would have a difficult time convincing any state in America to entrust him with the supervision of its lawbreaking youth.
The tube test uses rabbit plasma that has been inoculated with a staphylococcal colony (i.e., Gram-positive cocci which are catalase positive). The tube is then incubated at 37 °C for 1.5 hours. If negative, then incubation is continued up to 18 hours.
