Streptokok ( Streptococcus) je rod kokovitých grampozitivních bakterií z čeledi Streptococcacae, které charakterizuje řetízkové uspořádání (odtud jejich pojmenování z řeckého στρεπτος - streptos, což znamená ohebný, zkroucený - jako řetěz) Streptococcus, (genus Streptococcus), group of spheroidal bacteria belonging to the family Streptococcaceae. The term streptococcus (twisted berry) refers to the bacteria's characteristic grouping in chains that resemble a string of beads. Streptococci are microbiologically characterized as gram-positive and nonmotile Streptococcus. A genus of nonmotile (with few exceptions), non-spore-forming, aerobic to facultatively anaerobic bacteria (family Lactobacillaceae) containing gram-positive, spheric or ovoid cells that occur in pairs or in short or long chains. Dextrorotatory lactic acid is the main product of carbohydrate fermentation Strep is short for Streptococcus, a type of bacteria. There are several types. Two of them cause most of the strep infections in people: group A and group B. Strep throat - a sore, red throat. Your tonsils may be swollen and have white spots on them
Streptococcus pyogenes (GAS) bacteria have many components that contribute to the pathogen's ability to cause disease: Lipoteichoic acid on its surface helps the GAS bacteria to bind to epithelial cell membranes. M proteins (over 100 types on the GAS bacterial strains) help the bacteria resist immunologic host defenses Rod Streptococcus zahrnuje primární i sekundárně podmíněné patogenní bakterie. Vyskytují se jako komensálové na sliznici lidí. MORFOLOGIE: G+ koky ve dvojicích a řetízcích, nesporulující, nepohyblivé Streptococcus agalactiae je Gram-pozitivní, β-hemolytický kok.Narůstá v řetízkovitém seskupení.

Jde o původce infekcí dýchacích cest, kůže, systémových infekcí a příčinou poststreptokokových sterilních následků Group B strep (streptococcus) is a common bacterium often carried in the intestines or lower genital tract. The bacterium is usually harmless in healthy adults. In newborns, however, it can cause a serious illness known as group B strep disease Bacteria called group A Streptococcus (group A strep) can cause many different infections. These infections range from minor illnesses to very serious and deadly diseases. Learn more below about some of these infections, including symptoms, risk factors, treatment options, and how to prevent them Streptococcus pyogenes comprises the vast majority of the Lancefield group A streptococci, and is often used as a synonym for GAS. However, S. dysgalactiae can also be group A. S. pyogenes is a beta-hemolytic species of Gram positive bacteria that is responsible for a wide range of both invasive and noninvasive infections

[ Streptococcus agalactiae is a Gram-positive, non-motile, non-spore-forming coccus that is the only member of the Group B of the Lancefield antigen grouping.. It is a β-hemolytic, catalase-negative, facultative anaerobe that consists of ten different serotypes, separated on the basis of the immunologic reactions of their capsular polysaccharide
The Streptococcus bovis/Streptococcus equinus complex includes four major species that all belong to group D streptococci (GDS) . In the discussion below, the S. bovis/S. equinus complex is referred to as GDS. GDS are gram-positive cocci that are an important cause of bacteremia and infective endocarditis (IE) in adults. In addition, there is a. Streptococcus agalactiae or group B streptococcus (GBS)—a gram-positive, β-hemolytic organism in the Streptococcus genus that carries the Lancefield group B antigen. GBS are encapsulated organisms and ten antigenically distinct capsular serotypes have been described (1a, 1b, II-IX) Pneumococcal disease is caused by bacteria called Streptococcus pneumoniae (pneumococcus). People with pneumococcal disease can spread the bacteria to others when they cough or sneeze. Pneumococcus bacteria can cause infections in many parts of the body, including. Lungs (pneumonia) Ears (otitis) Sinuses (sinusitis Streptococcus pneumoniae (a major cause of human pneumonia) and Streptococcus mutans and other so-called viridans streptococci (among the causes of dental caries) do not possess group antigens. Three types of hemolysis reaction (alpha, beta, gamma) are seen after growth of streptococci on sheep blood agar Streptococcus halichoeri is an emerging pathogen with a variety of host species and zoonotic potential. It has been isolated from grey seals and other marine mammals as well as from human infections. Beginning in 2010, two concurrent epidemics were identified in Finland, in fur animals and domestic dogs, respectively. The fur animals suffered from a new disease fur animal epidemic necrotic.
The predominant streptococcal diseases in tilapia are Streptococcus agalactiae and Streptococcus iniae. Streptococcus agalactiae is further classified by MSD into two biotypes (Biotype 1 & Biotype 2), based on their unique disease characteristics. Each S. agalactiae biotype infection is caused by serotype-specific strains Group B Streptococcus also known as Group B Strep Infection (GBS) is a type of bacterial infection that can be found in a pregnant woman's vagina or rectum. This bacteria is normally found in the vagina and/or rectum of about 25% of all healthy, adult women.Women who test positive for GBS are said to be colonized Streptococcus strains are normally spherical or ovoid, less than 2 µm in diameter, occurring in chains or in pairs when grown in liquid media. Cells are nonmotile. Endospores are not formed. Gram‐positive. Virtually all species are facultatively anaerobic, some requiring additional CO 2 for growth S zastupuje Streptococcus.
