Cell division in streptococci occurs along a single axis, so as they grow, they tend to form pairs or chains that may appear bent or ...

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).

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 20, 2011 · Electron micrograph of Streptococcus pyogenes. From the Rockefeller University. Streptococci are nonmotile, Gram-positive, nonsporeforming bacteria, that live in pairs or chains of varying length. They are characteristically round or ovoid in shape. Most Streptococci are facultative anaerobes, although some are obligate anaerobes.
