Melissococcus
''Melissococcus'' is a genus of Gram-positive, catalase-negative, coccus-shaped lactic acid bacteria within the family Enterococcaceae. ''Melissococcus'' species were classified as ''Streptococcus ''Streptococcus'' is a genus of gram-positive ' (plural ) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota.

Lactobacillales
Lactobacillales are an order of gram-positive, low-GC, acid-tolerant, generally nonsporulating, nonrespiring, either rod-shaped ( bacilli) or spherical ( cocci) bacteria that share common metabolic and physiological characteristics. These bacteria, usually found in decomposing plants and milk products, produce lactic acid as the major metabolic end product of carbohydrate fermentation, giving them the common name lactic acid bacteria (LAB). Production of lactic acid has linked LAB with food fermentations, as acidification inhibits the growth of spoilage agents. Proteinaceous bacteriocins are produced by several LAB strains and provide an additional hurdle for spoilage and pathogenic microorganisms. Furthermore, lactic acid and other metabolic products contribute to the organoleptic and textural profile of a food item. The industrial importance of the LAB is further evidenced by their generally recognized as safe (GRAS) status, due to their ubiquitous appearance in food and ...

Bavariicoccus
''Bavariicoccus'' is a genus of bacteria of the phylum Bacillota. This genus contains a single species, ''Bavariicoccus seileri'', strains of which were originally isolated from German soft cheese. Bacterial taxonomists have suggested that ''Bavariicoccus'' may be more appropriately placed within the family Carnobacteriaceae The Carnobacteriaceae are a family of Gram-positive lactic acid bacteria.

Vagococcus
''Vagococcus'' is a genus of gram-positive bacteria. They are motile or nonmotile cocci which do not form spores. The name Vagococcus comes from Latin adjective ''vagus'' meaning wandering; and the Greek noun ''coccus'' a grain or berry, ''Vagococcus'' - wandering coccus, because ''Vagococcus fluvialis'' and some other Vagococcus species are motile, an unusual property for a lactic acid bacteria. History The first ''Vagococcus'' species, ''Vagococcus fluvialis ''Vagococcus fluvialis'' is a species of bacteria. The type strain of ''V. fluvialis'' is NCDO 2497. It rarely causes human infection. The only genetically proven case of ''V. fluvialis'' endocarditis was detected in the Cochin, India In ...'', was isolated from chicken feces in 1974. However, the genus was not recognized as distinct until 1989. References External links Vagococcus page on LPSN {{Taxonbar, from=Q16976645 Lactobacillales Bacteria genera ...

Pulmonary
The lungs are the primary organs of the respiratory system in humans and most other animals, including some snails and a small number of fish. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart. Their function in the respiratory system is to extract oxygen from the air and transfer it into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere, in a process of gas exchange. Respiration is driven by different muscular systems in different species. Mammals, reptiles and birds use their different muscles to support and foster breathing. In earlier tetrapods, air was driven into the lungs by the pharyngeal muscles via buccal pumping, a mechanism still seen in amphibians. In humans, the main muscle of respiration that drives breathing is the diaphragm. The lungs also provide airflow that makes vocal sounds including human speech possible. Humans have two lungs, one on the left and one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterococcus
''Enterococcus'' is a large genus of lactic acid bacteria of the phylum Bacillota. Enterococci are gram-positive cocci that often occur in pairs (diplococci) or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. Two species are common commensal Commensalism is a long-term biological interaction ( symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. This is in contrast with mutualism, in which both organisms benefit fr ... organisms in the intestines of humans: ''Enterococcus faecalis, E. faecalis'' (90–95%) and ''Enterococcus faecium, E. faecium'' (5–10%). Rare clusters of infections occur with other species, including ''E. casseliflavus'', ''Enterococcus gallinarum, E. gallinarum'', and Enterococcus raffinosus, ''E. raffinosus''. Physiology and classification Enterococci are facultative anaerobic organisms, i.e., they are capable of cellular respiratio ...

Gram-positive
In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through an optical microscope. This is because the thick peptidoglycan layer in the bacterial cell wall retains the stain after it is washed away from the rest of the sample, in the decolorization stage of the test. Conversely, gram-negative bacteria cannot retain the violet stain after the decolorization step; alcohol used in this stage degrades the outer membrane of gram-negative cells, making the cell wall more porous and incapable of retaining the crystal violet stain. Their peptidoglycan layer is much thinner and sandwiched between an inner cell membrane and a bacterial outer membrane, causing them to take up the counterstain ...
