Streptococcus is a genus of gm-positive cocus or spherical bacteria, which is related to the streptococcus family within the order lactobacillillase (lactic acid bacterium) in Pharlam Formulations. The cell division in Streptococci lies with one axis, so as they grow, they add or chain which can be twisted or twisted. (Unlike with Staphylococcus, which is split with many axes, making groups of irregular, grapes, etc.).

The word was made in 1877 by the Viennese surgeon Albert Theodor Billette (1829-1894), the prefix "Strepto-" (Ancient Greek: επτόςρεπτός, romanized, Strepto, lit. '' easily twisted, plural ''). Suffix "-Cocus" (from modern Latin: cocus, from ancient Greek: ςος, romani: kókkos, lit. 'cereals, seeds, berries'). Most striptococcus are oxidase-negative and catalyst-negative, and many faculty are enerobes (both are capable of development in aerobic and anaerobic form).

In 1984, many pre-indigenous bacteria in the genus Streptococcus were isolated in Genra Enterococcus and Lactococcus. At present, more than 50 species have been recognized in this genus. This gene has been found to be part of salivary microbios.

In addition to Streptococcal pharyngitis (Strepe Throat), some streptococcus species are responsible for many cases of pink eye, meningitis, bacterial pneumonia, endocarditis, irispillas, and necrotising fasciitis ('meat-eating bacterial infection). However, many streptococcal species are not pathogenic, and are part of normal human microbaita of the mouth, skin, intestine, and upper respiratory tract. Streptococci is also an essential ingredient in Emmentaler ("Swiss") Paneer Production.

Streptococcus species have been classified based on their hemolytic properties. Alpha-hemolytic species causes iron oxidation in hemoglobin molecules within the red blood cells, giving it a green color on the blood sugar. Beta-hemolytic species cause complete breakdown of red blood cells. On the bloodstream, this bacteria appears as clear areas of blood cells surrounding the colonies. The reason for the Gamma-Hemolithic species is not Hemolysis.

Beta-hemolytic streptococci is further classified by the Lancefeld group, a serotype classification (which describes the specific carbohydrate present on the bacterial cell wall). The 20 mentioned serotype has been named Lancelfeld Group A to V (excluding I and J). This system of classification was developed by Rockefeller University scientist Rebecca Lancefeld.

In medical settings, the most important groups are alpha-hemolytic Streptococci S Pneumonia and Streptococcus Viridans Group, and Beta-Hemolytic Streptococci of Lance Group A and B (also called "Group A Strepe" and "Group B Strepe")).
