Streptococcus dysgalactiae. Streptococcus dysgalactiae is a gram positive, beta-haemolytic, coccal bacterium belonging to the family Streptococcaceae. It is capable of infecting both humans and animals, but is most frequently encountered as a commensal of the alimentary tract, genital tract, or less commonly, as a part of the skin flora.
Streptococcus anginosus is part of the human bacteria flora, but can cause diseases including brain and liver abscesses under certain circumstances. The habitat of S. anginosus is a wide variety of sites inside the human body. Cultures have been taken from the mouth, sinuses, throat, feces, and vagina, yielding both hemolytic (mouth) and ...
Streptolysin O is an oxygen-sensitive cytotoxin, secreted by most group A Streptococcus (GAS), and interacts with cholesterol in the membrane of eukaryotic cells (mainly red and white blood cells, macrophages, and platelets), and usually results in beta-hemolysis under the surface of blood agar.
Streptococcus salivarius subsp. thermophilus Andrewes & Horder 1906. Streptococcus salivarius is a species of spherical, gram-positive, facultative anaerobic lactic acid bacteria [1] that is both catalase and oxidase negative. S. salivarius colonizes (usually in chains) the oral cavity and upper respiratory tract of humans just a few hours ...
Streptococcus constellatus subsp. viborgensis Jensen et al., 2013. Streptococcus constellatus is a species of Streptococcus [2] bacteria that is part of the normal flora in the oral cavity, urogenital region, and intestinal tract. However, it can frequently cause purulent infections in other parts of the body. [3]
Streptococcus zooepidemicus. Streptococcus zooepidemicus is a Lancefield group C streptococcus that was first isolated in 1934 by P. R. Edwards, and named Animal pyogens A. [1] It is a mucosal commensal and opportunistic pathogen that infects several animals and humans, but most commonly isolated from the uterus of mares.
Streptococcosis is an infectious disease caused by bacteria of the genus Steptococcus. This disease is most common among horses, guinea pigs, dogs, cats, and fish with symptoms varying based on the streptococcal species involved. [1] In humans, this disease typically involves a throat infection and is called streptococcal pharyngitis or strep ...
Streptococcus oralis is a Gram positive viridans streptococcus of the Streptococcus mitis group. [2][3] S. oralis is one of the pioneer species associated with eubiotic dental pellicle biofilms, and can be found in high numbers on most oral surfaces. [4][5] It has been, however, found to be an opportunistic pathogen as well. [2]
