Streptococcus is a genus of gram-positive coccus (pl.: cocci) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. 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 ...
streptococcus, (genus Streptococcus), group of spheroidal bacteria belonging to the family Streptococcaceae. The term streptococcus (“twisted berry”) refers to the bacteria’s characteristic grouping in chains that resemble a string of beads. Streptococci are microbiologically characterized as gram-positive and nonmotile.

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.

The Streptococcaceae are distinguished from the Micrococcaceae in that the former are catalase negative and the latter are catalase positive. In the Streptococcaceae family, only streptococci and aerococci are regularly isolated from specimens of human origin (see Table 2.1). There have been recent taxonomic changes in the family Streptococcaceae.
Aug 3, 2016 · This paper again highlights the "art" of medicine in the need to carefully weigh each situation rather than to have "knee jerk" responses to clinical microbiological data. Streptococcus species answers are found in the Johns Hopkins ABX Guide powered by Unbound Medicine. Available for iPhone, iPad, Android, and Web.
Peptostreptococcaceae. The Peptostreptococcaceae are a family of Gram-positive bacteria in the class Clostridia . Several members of the Peptostreptococcaceae are well known inhabitants of the digestive tract. Microbiome studies of animal feces have corroborated this. Notably, an unclassified group of Peptostreptococcaceae has been reported ...
