Introduction. The genus Streptococcus currently comprises 99 recognized species, many of which are associated with disease in humans and animals ( www.bacterio.net/streptococcus.html ). The streptococci are gram-positive cocci that are usually arranged in chains of varying lengths and in some cases pairs.

Jun 8, 2018 · Streptococcus (family Streptococcaceae) A genus of Gram-positive, non- motile bacteria in which the cells are spherical to ovoid, and often occur in pairs or chains. There are many species, found chiefly as parasites and pathogens in warm-blooded animals, including humans.
Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Older cultures may lose their Gram-positive character. Most streptococci are facultative anaerobes, and some are obligate (strict) anaerobes. Most require enriched media (blood agar).
Streptococcus is a genus of spherical Gram-positive bacteria belonging to the phylum Firmicutes and the lactic acid bacteria group. They are cocci, meaning that they are shaped like spheres or circles.
