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 ...
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 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 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 after birth, making further exposure to the bacteria harmless in most circumstances.
Leuconostoc mesenteroides. Leuconostoc mesenteroides is a species of lactic acid bacteria associated with fermentation, under conditions of salinity and low temperatures (such as lactic acid production in fermented sausages). [2] In some cases of vegetable and food storage, it was associated with pathogenicity (soft rot, slime and unpleasant ...
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.
Streptococcus thermophilus formerly known as Streptococcus salivarius subsp. thermophilus[2][1] is a gram-positive bacterium, and a fermentative facultative anaerobe, of the viridans group. [3] It tests negative for cytochrome, oxidase, and catalase, and positive for alpha-hemolytic activity. [3] It is non-motile and does not form endospores. [3]
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]
