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.

Sep 28, 2023 · Micrococcus luteus, often simply referred to as M. luteus, is a Gram-positive, spherical bacterium belonging to the genus Micrococcus. This bacterium is commonly found in various environments, including soil, dust, water, and on the human skin.

Few pieces of research have focused on Micrococcus luteus bloodstream infection (BSI) because of its low incidence; hence data is needed to illustrate this uncommon infection. This study aimed to explore the clinical characteristics of patients with M. luteus BSI.

• M. luteus was first known as Micrococcus lysodeikticus and was discovered by Alexander Fleming in 1928. • Its name stands for: microscopic (micro), of spherical shape (coccus), and …

Metagenomic sequencing identified M. luteus as the predominant species in the sample, confirming infection. They were identified as M. luteus with a high confidence level of 98.99% using mass spectrometry.

Aug 2, 2012 · The type species is M. luteus (Schroeter; Cohn, 1872). Emended descriptions of the genus Micrococcus and the species M. luteus and M. lylae were given in 2002, on the basis of a polyphasic approach to the classification of nine yellow-pigmented, spherical bacterial strains isolated from various sources.

Apr 25, 2021 · Micrococcus luteus is a bacterium that belongs to the group of gram-positive ones. It is found as part of the microbiota of the body surfaces of mammals, as well as some internal areas of the body.

Micrococcus luteus are Gram-positive cocci mostly arranged in tetrads and larger than Staphylococcus. They are positive for catalase and oxidase ( modified). They grow in circular, entire, convex, and creamy yellow-pigmented colonies with diameters of approximately 4 mm after 2-3 days at 37°C.

Micrococcus luteus is a Gram-positive, spherical bacterium commonly found on human skin. It is an obligate aerobe, meaning it requires oxygen to survive. While usually harmless, M. luteus can cause infections in individuals with weakened immune systems.

Some species of Micrococcus, such as M. luteus (yellow) and M. roseus (red) produce yellow or pink colonies when grown on mannitol salt agar. Isolates of M. luteus have been found to overproduce riboflavin when grown on toxic organic pollutants like pyridine.
