Streptococcus is a genus of gram-positive or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. [2] . Cell division in streptococci occurs along a single axis, thus when growing they tend to form pairs or chains, which may appear bent or twisted.
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.
Streptococcus is a member of Gram-positive lactic acid-producing bacteria (LAB) that belonged to Firmicutes phylum. Many strains of Streptococcus are non-pathogenic and occur as commensal flora on the skin, the oral cavity, nasopharynx, upper respiratory tract, urogenital, and gastrointestinal tracts.
CLINICAL. Group A streptococci: S. pyogenes (see separate pathogen module). Group B streptococci (S. agalactiae): Cause of neonatal sepsis/meningitis, puerperal sepsis, chorioamnionitis, peripartum endometritis, bacteremia (often without clear source), skin and soft-tissue infections, septic arthritis, pneumonia, endocarditis, osteomyelitis.
We studied Pseudomonas aeruginosa, Streptococcus pyogenes, P. putida, and S. felis. For an article about multiple genera, some of which have the same abbreviation, write out first mention of new species.
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 spp. (bacterium) The genus Streptococcus belongs to the family Streptococcaceae. They are spherical, chain-forming, Gram-positive bacteria. Their behavior concerning hemolysis and the Lancefield-classification divide the different species into serogroups.
Streptococcal infections are any type of infection caused by the streptococcal, or “strep” group of bacteria. There are a number of different streptococci, which create symptoms ranging from a...
The genus Streptococcus contains gram-positive cocci that characteristically are arranged in chains (see colorplate 2). A number of species of streptococci are normally found among the normal flora of human skin and mucous membranes, particularly those of the upper respiratory tract.
Overview. Streptococcus bacteria is Gram-positive and are generally spherical in shape. They are commonly found in the mucous membrane of the mouth and respiratory tract etc where they have been associated with a number of diseases and infections including sepsis, pneumonia, and pharyngitis.
