Mycobacterium xenopi is a slow-growing scotochromogenic species of Mycobacterium. It was first reported by Schwabacher in 1959, having been isolated in lesions found on a Xenopus laevis, but the possibility of human infection was not confirmed until 1965. It has been cultured from hot and cold water taps, hospital hot water generators and storage tanks, and other environmental sources.
Micrococcus luteus is a Gram-positive, to Gram-variable, nonmotile, coccus, tetrad-arranging, pigmented, saprotrophic bacterium that belongs to the family Micrococcaceae. 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. The bacterium also colonizes the human mouth, mucosae, oropharynx and upper respiratory tract.
Staphylococcus hominis is a coagulase-negative member of the bacterial genus Staphylococcus, consisting of Gram-positive, spherical cells in clusters. It occurs very commonly as a harmless commensal on human and animal skin and is known for producing thioalcohol compounds that contribute to body odour. Like many other coagulase-negative staphylococci, S. hominis may occasionally cause infection in patients whose immune systems are compromised, for example by chemotherapy or predisposing illness.
The family Micrococcaceae includes bacterial genera of Gram positive cocci that inhabit the air and skin, such as Micrococcus luteus.
The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea. It denotes the rules for naming taxa of bacteria, according to their relative rank. As such it is one of the nomenclature codes of biology.
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. They are catalase positive, oxidase positive, indole negative and citrate negative. Micrococcus has a substantial cell wall, which may comprise as much as 50% of the cell mass. The genome of Micrococcus is rich in guanine and cytosine (GC), typically exhibiting 65 to 75% GC-content. Micrococci often carry plasmids that provide the organism with useful traits.
Mycobacteroides chelonae is a species of bacteria from the phylum Actinomycetota belonging to the genus Mycobacteroides. Mycobacteroides chelonae is a rapidly growing mycobacterium that is found all throughout the environment, including sewage and tap water. It can occasionally cause opportunistic infections of humans.
Mycobacterium haemophilum is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Staphylococcus simulans is a Gram-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of single, paired, and clustered cocci.
Macrococcus is a genus of Gram-positive cocci belonging to the family Staphylococcaceae. The genus was created in 1998.
Pasteurella canis is a Gram-negative, nonmotile, penicillin-sensitive coccobacillus of the family Pasteurellaceae. Bacteria from this family cause zoonotic infections in humans, which manifest themselves as skin or soft-tissue infections after an animal bite. It has been known to cause serious disease in immunocompromised patients.
Pasteurella stomatis, is a Gram-negative, nonmotile, penicillin-sensitive coccobacillus of the family Pasteurellaceae. Bacteria from this family cause zoonotic infections in humans. These infections manifest themselves as skin or soft tissue infections after an animal bite.
Brachyspira innocens is a species of bacteria. It is thought to be a commensal bacterium.
Rothia kristinae is a Gram positive bacterium. R. kristinae is a common human skin organism, but can cause opportunistic infections in humans.
Vibrio furnissii is a Gram-negative, rod-shaped bacterium. Its type strain is ATCC 35016. V. furnissii is aerogenic (gas-producing), and uses L-rhamnose, L-arginine, L-arabinose, maltose, and D-mannitol, but not L-lysine, L-ornithine, or lactose. It has been isolated from patients with gastroenteritis, bacteremia, skin lesions, and sepsis.
Kocuria is a genus of gram-positive bacteria. Kocuria is named after Miroslav Kocur, a Slovakian microbiologist. It has been found in the milk of water deer and reindeer. Cells are coccoid, resembling Staphylococcus and Micrococcus, and can group in pairs, chains, tetrads, cubical arrangements of eight, or irregular clusters. They have rigid cell walls and are either aerobic or facultative anaerobic. Kocuria can usually survive in mesophilic temperatures.
Kytococcus sedentarius is a marine dwelling Gram positive bacterium in the genus Kytococcus. It is known for the production of polyketide antibiotics as well as for its role as an opportunistic pathogen. It is strictly aerobic and can only grow when amino acids are provided.
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. K. rosea has also been found to cause urinary tract infections in people with weakened immune systems.
Brachybacterium conglomeratum is a species of Gram positive, facultatively anaerobic, whitish yellow to pale brown pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. The species was originally classified as Micrococcus conglomeratus for over 60 years, until most species were reclassified as Brachybacterium conglomeratum in 1995. The name is derived from Latin conglomeratum.
Kocuria varians is a gram-positive species of bacteria in the genus Kocuria. It has been isolated from milk, meat, skin, soil, and beach sand. It is 0.9 to 1.5 micrometers in diameter, and occurs in clusters, which can be up to 4 millimeters in diameter and are yellow. It is known to cause ocular infections, brain abscesses, and endophthalmitis.
