Mammaliicoccus sciuri, previously Staphylococcus sciuri, is a Gram-positive, oxidase-positive, coagulase-negative member of the bacterial genus Mammaliicoccus consisting of clustered cocci. The type subspecies M. sciuri subsp. sciuri was originally known as Staphylococcus sciuri subsp. sciuri and used to categorize 35 strains shown to use cellobiose, galactose, sucrose, and glycerol. [1]
In 2020, Madhaiyan et al. renamed the genus for M. sciuri from Staphylococcus to Mammaliicoccus. [2]
Staphylococcus saprophyticus is a Gram-positive coccus belonging to the genus Staphylococcus. S. saprophyticus is a common cause of community-acquired urinary tract infections.
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.
Bifidobacterium animalis is a gram-positive, anaerobic, rod-shaped bacterium of the Bifidobacterium genus which can be found in the large intestines of most mammals, including humans.
Cronobacter sakazakii, which before 2007 was named Enterobacter sakazakii, is an opportunistic Gram-negative, rod-shaped, pathogenic bacterium that can live in very dry places, otherwise known as xerotolerance. C. sakazakii utilizes a number of genes to survive desiccation and this xerotolerance may be strain specific. The majority of C. sakazakii cases are adults but low-birth-weight preterm neonatal and older infants are at the highest risk. The pathogen is a rare cause of invasive infection in infants, with historically high case fatality rates (40–80%).
Cronobacter is a genus of Gram-negative, facultatively anaerobic, oxidase-negative, catalase-positive, rod-shaped bacteria of the family Enterobacteriaceae. Several Cronobacter species are desiccation resistant and persistent in dry products such as powdered infant formula. They are generally motile, reduce nitrate, use citrate, hydrolyze esculin and arginine, and are positive for L-ornithine decarboxylation. Acid is produced from D-glucose, D-sucrose, D-raffinose, D-melibiose, D-cellobiose, D-mannitol, D-mannose, L-rhamnose, L-arabinose, D-trehalose, galacturonate and D-maltose. Cronobacter spp. are also generally positive for acetoin production and negative for the methyl red test, indicating 2,3-butanediol rather than mixed acid fermentation. The type species of the genus Cronobacter is Cronobacter sakazakii comb. nov.
Mycoplasma mycoides is a bacterial species of the genus Mycoplasma in the class Mollicutes. This microorganism is a parasite that lives in ruminants. Mycoplasma mycoides comprises two subspecies, mycoides and capri, which infect cattle and small ruminants such as goats respectively.
Staphylococcus is a genus of Gram-positive bacteria in the family Staphylococcaceae from the order Bacillales. Under the microscope, they appear spherical (cocci), and form in grape-like clusters. Staphylococcus species are facultative anaerobic organisms.
Macrococcus is a genus of Gram-positive cocci belonging to the family Staphylococcaceae. The genus was created in 1998.
Staphylococcus succinus is a Gram-positive coccoid bacterium belonging to the genus Staphylococcus.
Staphylococcus cohnii is a Gram-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of clustered cocci. The species commonly lives on human skin; clinical isolates have shown high levels of antibiotic resistance. A strain of S. cohnii was found to contain a mobile genetic element very similar to the staphylococcal cassette chromosome encoding methicillin resistance element seen in Staphylococcus aureus.
Staphylococcus condimenti is a Gram-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of single, paired, and clustered cocci. Strains of this species were originally isolated from fermenting soy sauce mash and are positive for catalase, urease, arginine dihydrolase, nitrate reductase, beta-galactosidase, and phosphatase activity.
Staphylococcus vitulinus is a Gram-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of clustered cocci. The species was originally isolated from food and animals and was named Staphylococcus vitulus. The name was later changed to Staphylococcus vitulinus for correct Latin grammar.
Staphylococcus lentus is a Gram-positive, oxidase-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of clustered cocci. The species was originally classified as a subspecies; its name is a combination derived from Staphylococcus sciuri subsp. lentus.
Staphylococcus equorum is a gram-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of clustered cocci. Originally isolated from the skin of healthy horses, this species contains a cell wall similar to that of Staphylococcus xylosus.
Staphylococcus massiliensis is a Gram-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of clustered cocci. Strains of this species were first isolated from a human brain abscess and were found to be most closely related to Staphylococcus piscifermentans, Staphylococcus condimenti, Staphylococcus carnosus subsp. carnosus, Staphylococcus carnosus subsp. utilis, and Staphylococcus simulans. A subsequent study found that S. massiliensis may actually be part of the human skin microbiome and may have been a contaminant of brain abscess-derived samples.
Staphylococcus piscifermentans is a Gram-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of clustered cocci. This species was originally isolated from fermented fish in Thailand. A later study found a strain of S. piscifermentans in dog feces. The species is used in the preparation of fermented foods along with Staphylococcus carnosus; both species reduce nitrate and produce ammonia.
Polynucleobacter necessarius is a bacterium of the genus Polynucleobacter.
Staphylococcus schleiferi is a Gram-positive, cocci-shaped bacterium of the family Staphylococcaceae. It is facultatively anaerobic, coagulase-variable, and can be readily cultured on blood agar where the bacterium tends to form opaque, non-pigmented colonies and beta (β) hemolysis. There exists two subspecies under the species S. schleiferi: Staphylococcus schleiferi subsp. schleiferi and Staphylococcus schleiferi subsp. coagulans.
Bifidobacterium thermacidophilum is a Gram-positive, rod-shaped species of bacteria. Strains of this species were originally isolated from an anaerobic digester used to treat wastewater from a tofu farm. The species is thermophilic and can grow at a temperature of 49.5 °C.
Staphylococcus agnetis is a Gram positive, coagulase-variable member of the bacterial genus Staphylococcus. Strains of this species were originally isolated from the milk and teats of cows with mastitis. This species is not known to infect humans.
