Description: | Gram-positive, nonmotile, nonsporeforming coccus that occurs in
chains or in pairs of cells. Individual cells are round-to-ovoid
cocci, 0.6-1.0 micrometer in diameter. It is a catalase-negative
aerotolerant anaerobe (facultative anaerobe). It requires enriched
medium containing blood in order to grow. It has a capsule composed
of hyaluronic acid. Its genome has low G+C content.
Serotpye M3 strains are a common cause of severe invasive infections with unusually high rates of morbidity and mortality. The strain MGAS315 has been isolated from a patient with streptococcal toxic shock syndrome. |
Properties: | Number of membranes : 1 Presence of a flagella : No Number of inteins : 0 |
