Streptococcus definition of Streptococcus by Medical

Strep throat is caused by infection with a bacterium known as Streptococcus pyogenes, also called group A streptococcus. Streptococcal bacteria are contagious. They can spread through droplets when someone with the infection coughs or sneezes, or through shared food or drinks العِقْديّة المقيِّحة أو المكورة العقدية المقيحة (باللاتينية: Streptococcus pyogenes) نوع من البكتيريا إيجابية الغرام. ومثل كل العقديات الأخرى، لها دور مهم في الأمراض التي تصيب الإنسان. الإصابة بها نادراً ماتحدث، لكنها عادة ما. 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 Group B streptococcus, also known as group B strep or GBS, is a type of bacteria that can cause illness in people of all ages, though it can be particularly severe in newborns, most commonly. Infection with Streptococcus pyogenes, a beta-hemolytic bacterium that belongs to Lancefield serogroup A, also known as the group A streptococci (GAS), causes a wide variety of diseases in humans.A ubiquitous organism, S pyogenes is the most common bacterial cause of acute pharyngitis, accounting for 15-30% of cases in children and 5-10% of cases in adults. [

Streptococcus dentapri, isolated from the oral cavities of wild boars, exhibited high 16S rRNA gene sequence similarities with members of the Pyogenic and the Mutans group, but based on the distinct phenotypic and genotypic characteristics, and the phylogenetic evidence, it is a member of the last group 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 Subsequent classification, based on carbohydrates in the cell wall, divides streptococci into Lancefield groups A through H and K through T (see Table: Lancefield Classification).Viridans streptococci form a separate group that is difficult to classify streptococcus (strĕp'təkŏk`əs), any of a group of gram-positive bacteria, genus Streptococcus, some of which cause disease. Streptococci are spherical and divide by fission, but they remain attached and so grow in beadlike chains. The incidence and severity of streptococcal diseases decreased dramatically after the introduction of antibiotics antibiotic

  1. Streptococcus is a genus of spherical Gram-positive bacteria, belonging to the phylum Firmicutes and the lactic acid bacteria group. Cellular division occurs along a single axis in these bacteria, and thus they grow in chains or pairs, hence the name — from Greek streptos, meaning easily bent or twisted, like a chain
  2. Streptococcus in the news. Streptococcus suis, a species of Streptococci found in pigs, has recently caused a rash of human infections in China. Human-to-human contact does not seem to be the bacteria's mode of transport, rather, Streptococcus suis is contracted by contact with or the consumption of infected pigs. As of now the death toll from this illness is 37, an unusually high mortality rate causing some scientists to suspect that swine flu may not be the disease
