Salinicoccus
''Salinococcus'' is a genus of Gram-positive cocci belonging to the family Staphylococcaceae. The genus name is derived from Latin ''salinus'' - saline, and Greek ''kokkos'' - a grain or berry A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a stone or pit, although many pips or seeds may be present. Common examples are strawberries, raspb ...).

Jeotgalicoccus
''Jeotgalicoccus'' is a genus of Gram-positive, facultatively anaerobic, and halotolerant to halophilic bacteria. The cells are coccoid. The genus is named after the Korean fish sauce jeotgal ''Jeotgal'' () or ''jeot'' (), translated as salted seafood, is a category of salted preserved dishes made with seafood such as shrimps, oysters, clams, fish, and roe. Depending on the ingredients, ''jeotgal'' can range from flabby, solid piec ..., whence these bacteria were first isolated.

Macrococcus
''Macrococcus'' is a genus of Gram-positive cocci belonging to the family Staphylococcaceae. The genus was created in 1998.Kloos, W. E., D. N. Ballard, C. G. George, J. A. Webster, R. J. Hubner, W. Ludwig, K. H. Schleifer, F. Fiedler, and K. Schubert. 1998.

Int. J. Syst. Bacteriol. 48:859-877 History The first recognised species in this genus (''Macrococcus caseolyticus'') was initially named ''Micrococcus caseolyticus'' by Evans in 1916. It was then renamed ''Staphylococcus caseolyticus'' by Schleifer ''et al'' in 1982. It received its current designation in 1998 by Kloos ''et al''. Description Members of the genus ''Macrococcus'' are Gram-positive, nonmotile, non-spore-forming cocci that are coagulase negative and catalase positive. They can be disti ...

Staphylococcus
''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 (capable of growth both aerobically and anaerobically). The name was coined in 1880 by Scottish surgeon and bacteriologist Alexander Ogston (1844–1929), following the pattern established five years earlier with the naming of ''Streptococcus''. It combines the prefix "staphylo-" (from grc, σταφυλή, staphylē, bunch of grapes), and suffixed by the Modern (from ). Staphylococcus was one of the leading infections in hospitals and many strains of this bacterium have become antibiotic resistant. Despite strong attempts to get rid of them, staph bacteria stay present in hospitals, where they can infect people who are most at risk of infection. Staphylococcus includes at least 43 species. Of these, nine have two su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methicillin-resistant Staphylococcus Aureus
Methicillin-resistant ''Staphylococcus aureus'' (MRSA) is a group of Gram-positive bacteria that are genetically distinct from other strains of ''Staphylococcus aureus''. MRSA is responsible for several difficult-to-treat infections in humans. It caused more than 100,000 deaths attributable to antimicrobial resistance in 2019. MRSA is any strain of ''S. aureus'' that has developed (through natural selection) or acquired (through horizontal gene transfer) a multiple drug resistance to beta-lactam antibiotics. Beta-lactam (β-lactam) antibiotics are a broad-spectrum group that include some penams (penicillin derivatives such as methicillin and oxacillin) and cephems such as the cephalosporins. Strains unable to resist these antibiotics are classified as methicillin-susceptible ''S. aureus'', or MSSA. MRSA is common in hospitals, prisons, and nursing homes, where people with open wounds, invasive devices such as catheters, and weakened immune systems are at greater risk of healt ...

Gemella
''Gemella'' is a genus of Gram-positive bacteria that thrive best at high partial pressure of CO2. Description A Gemella species was first described as Neisseria hemolysans in 1938. It was reclassified as a new genus in 1960 when strains were found to be distinct enough from Neisseria to require a new genus. The name was suggested based on the organism being a diplococcus and gemellus is the diminutive of geminus, which is Latin for twin. They are facultatively anaerobic and give negative reactions to both oxidase and catalase tests. They are obligately fermentative, producing either a mixture of acetic and lactic acids or an equimolar molar mixture of acetic acid and CO2. For example, ''G. haemolysans'' ferments glucose forming a mixture of acetic and lactic acids in the absence of oxygen, whereas when oxygen is present, it forms acetic acid and CO2. Clinical importance ''Gemella'' bacteria are primarily found in the mucous membranes of humans and other animals, particula ...

Family (taxonomy)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
