The family Streptococcaceae include Gram-positive spherical bacteria growing in chains or pairs. They are typically non-motile, non-spore forming facultative anaerobes and oxidase negative. They attack carbohydrates fermentatively and are catalase negative.
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).
