However, skin variety provides a rich and diverse habitat for bacteria. Most come from four phyla: Actinomycetota (51.8%), Bacillota (24.4%), Pseudomonadota (16.5%), and Bacteroidota (6.3%). [5] Ecology of the 20 sites on the skin studied in the Human Microbiome Project. There are three main ecological areas: sebaceous, moist, and dry.
Kocuria has been found to live on human skin and oral cavity. [6] It is generally considered non-pathogenic but can be found in some infections. Specific infection associated with Kocuria are urinary tract infections, cholecystitis, [7] catheter-associated bacteremia, [8] dacryocystitis, [9] canaliculitis, keratitis, [10] native valve endocarditis, [11] peritonitis, [12] descending necrotizing ...
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 ...
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]
It is the second largest of the human body and made of various bacteria, viruses, fungi and protozoa. [14] These organisms play an important role in oral and overall health. Anthony Van Leeuwenhoek was the first to view these organisms using a microscope he created. [ 14 ]
The human skin is the outer covering of the body and is the largest organ of the integumentary system. The skin has up to seven layers of ectodermal tissue guarding muscles, bones, ligaments and internal organs. Human skin is similar to most of the other mammals' skin, and it is very similar to pig skin.
It is catalase positive, oxidase positive, and exhibits strictly aerobic metabolism. Optimum growth temperature is 25–37 °C (77–99 °F). It is primarily isolated from human skin, and is one of the major causes of pitted keratolysis. [4] [5] It was once considered a species of the genus Micrococcus. [6]
