Group A Streptococcus bacteria causes disease ranging from streptococcal sore throat (strep throat) to necrotizing fasciitis (flesh-eating disease). They can also cause scarlet fever, rheumatic fever, postpartum fever, and streptococcal toxic shock syndrome.  Overview: Streptococcus agalactiae (also known as group-B streptococcus or beta-strep) is a Gram-positive coccus, non-motile, non-spore-forming, catalase-negative, spherical or ovoid, and less than 2 µm (micrometres) in diameter; it is usually β-haemolytic and can grow in pairs or short chains (Figure 1).  Streptococcus mutans is facultatively anaerobic, Gram-positive coccus-shaped bacterium commonly found in the human oral cavity and is a significant contributor to tooth decay. Streptococcus mutans is a Gram-positive bacterium that is the primary causative agent in the formation of dental cavities in humans. Gram-positive bacteria are those that are stained dark-blue or violet by Gram staining. A term used to refer to any member of the genus Streptococcus. /Strep·to·coc·cus/ (-kok´us) a genus of gram-positive, facultatively anaerobic cocci occurring in pairs or chains; it is separable into the pyogenic group, the viridans group, the enterococcus group, and the lactic group. Streptococcus. a genus of gram-positive, predominantly facultatively anaerobic cocci in the family Streptococcaceae occurring in pairs or chains. It is classifiable in several ways, none of them completely satisfactory in terms of species designation. Sherman's classification was based on tolerance tests. Streptococcus is a genus of coccus (spherical) gram-positive bacteria belonging to the phylum Firmicutes and the Lactobacillales (lactic acid bacteria) order.  Streptococcus is a genus of spherical Gram-positive bacteria belonging to the phylum Firmicutes and the lactic acid bacteria group. S. mutan s, a member of the human oral flora, is widely recognized as the main causative agent of dental cavities. Streptococcus mutans is a Gram-positive bacterium that is the primary causative agent in the formation of dental cavities in humans. Gram-positive bacteria are those that are stained dark-blue or violet by Gram staining. Streptococcus pneumoniae are Gram-positive bacteria in the shape of a slightly pointed cocci. They are usually found in pairs (diplococci), but are also found singly and in short chains.  Streptococcus. a genus of gram-positive, facultatively aerobic cocci (family Streptococcaceae) occurring in pairs or chains. It is separable into the pyogenic group, the viridans group, the enterococcus group, and the lactic group. Streptococcus. a genus of gram-positive, predominantly facultatively anaerobic cocci in the family Streptococcaceae occurring in pairs or chains. It is classifiable in several ways, none of them completely satisfactory in terms of species designation. Sherman's classification was based on tolerance tests. Streptococcus pneumoniae cells are Gram-positive, lancet-shaped cocci (elongated cocci with a slightly pointed outer curvature). Usually, they are seen as pairs of cocci (diplococci), but they may also occur singly and in short chains. When cultured on blood agar, they are alpha hemolytic.  These 10 animal facts will amaze you. Streptococcus bacteria is a genus of coccus, or spherelike, Gram-positive, chained bacteria belonging to the lactic acid bacteria (LAB) group. Individual streptococcus cells may be round or ovoid and all lack the enzyme catylase. Because these cells divide along a single plane, streptococci occur in pairs or in chains.
