Streptococcus salivarius is a species of spherical, Gram-positive bacteria which colonize the mouth and upper respiratory tract of humans a few hours after birth, making further exposure to the bacteria harmless. The bacterium is an opportunistic pathogen which rarely makes its way into the bloodstream where it is associated with septicemia cases in people with neutropenia. It has different characteristics when exposed to different environmental nutrients. In the lab a SYTA plate is used...

Streptococcus pyogenes is a spherical, Gram-positive bacterium is the cause of Group A streptococcal infections. It displays streptococcal group A antigen on its cell wall. When it is cultured on blood agar plates it produces large zones of beta-hemolysis. They are catalase-negative and in ideal conditions it has an incubation period of about 1-3 days. It is an infrequent part of the skin flora. It is the cause of many important human diseases, ranging from mild superficial skin infections...

Streptococcus pneumoniae, or pneumococcus, is Gram-positive, alpha-hemolytic, bile-soluble aerotolerant, anaerobic member of the genus Streptococcus. It was recognized as a major cause of pneumonia in the late 19th century and is thus the subject of many humoral immunity studies. It causes many other types of pneumococcal infections other than pneumonia including acute sinusitis, otitis media, meningitis, bacteremia, sepsis, septic arthritis, peritonitis, cellulites, and brain abscess. It...

Streptococcus oralis is a Gram positive bacterium that grows characteristically in chains. On a Wilkins-Chalgren agar plate it will form slam white colonies. It is classified as a member of the streptococcus mitis group and is found in high numbers in the oral cavity. S. oralis produce neuraminidase and an IgA protease and cannot bind α-amylase.

Streptococcus mutans is a Gram-positive cocci, Facultative anaerobic bacterium commonly found in the human oral cavity and is a significant contributor to tooth decay. J Kilian Clarke first described the microbe in 1924. The first colonizers of the tooth surface are mainly Neisseria spp. and streptococci, including S. mutans. The pioneer species changes the local environmental conditions through growth and metabolism thus allowing more fastidious organisms to further colonize after them,...
