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 ...

Gemella Morbillorum
''Gemella morbillorum'' is a species of bacteria within the genus ''Gemella''. It is a facultative anaerobic Gram positive coccus usually preferring capnophilic or microaerophilic environments. From its discovery in 1917 (by R. Tunnicliff) until 1988, it was known as ''Streptococcus morbillorum'' (and briefly as ''Peptostreptococcus morbillorum'' ). The name change followed closer examination with DNA filter hybridization (by Kilpper-Balz and Schleifer) which found it was very close to the species ''Gemella haemolysans''. Pathogenicity ''G. morbillorum'' is rarely a cause of disease in humans, though it may be found benignly in the oropharyngeal area. Infections, when found, are similar to ''viridans Streptococci'' in range. Cases have been reported of endovascular infections (predominantly endocarditis) and also acute invasive infections. It has also been reported as among the most common bacteria present in teeth with cysts that do not resolve after repeated root canal treat ...

Staphylococcaceae
The Staphylococcaceae are a family of Gram-positive bacteria that includes the genus ''Staphylococcus'', noted for encompassing several medically significant pathogens.

Bacilli
Bacilli is a taxonomic class of bacteria that includes two orders, Bacillales and Lactobacillales, which contain several well-known pathogens such as ''Bacillus anthracis'' (the cause of anthrax). ''Bacilli'' are almost exclusively gram-positive bacteria. The name ''Bacillus'', capitalized and italicized, refers to a specific genus of bacteria. The name Bacilli, capitalized but not italicized, can also refer to a less specific taxonomic group of bacteria that includes two orders, one of which contains the genus ''Bacillus''. When the word is formatted with lowercase and not italicized, 'bacillus', it will most likely be referring to shape and not to the genus at all. Ambiguity Several related concepts make use of similar words, and the ambiguity can create considerable confusion. The term "''Bacillus''" (capitalized and italicized) is also the name of a genus (''Bacillus anthracis'') that, among many other genera, falls within the class Bacilli. The word "bacillus" (or its plur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxygen
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.Atkins, P.; Jones, L.; Laverman, L. (2016).''Chemical Principles'', 7th edition. Freeman. Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as ...
