|Categories:||Zoonotic; causes hemolysis|
|Etymology:||Genus name: twisted (like a chain) cocci (coccus means a grain or a berry and referrs to any spherical microorganism).|
Species epithet: from a dog.
|Significance:||S. canis is often isolated from dogs and cats, but it can also cause bovine mastitis. The bacterium causes sporadic cases of mastitis in certain heards and larger outbreaks in other herds by transmission between cows at milking.

|Type Strain:||STR-T1 = ATCC 43496 = CCUG 27661|
||Medium sized β-hemolytic colonies (1-2 mm in diameter) after incubation for 24 h at 37°C on blood agar.|
|Micromorphology:||Cocci, which appear in pairs or short chains.|
|Gram +/Gram -:||G+|
|Other Enzymes:||Esculinase +, β-galactosidas +, hippuricase -, hyaluronidase -, urease -.|
|Biochemical Tests:||Voges-Proskauer -|
|Fermentation of carbohydrates:||
|Disease:||Dog, cat and rat: opportunistic infections, e.g. abscesses, lymphadenitis, mastitis, prostatitis, pyoderma, pyometra and "puppy strangles".
|Hosts:||Dog, cattle, cat and rat.|
|16S rRNA Seq.:|
||About 100 species have been described within the genus Streptococcus. Many species within the genus Enterococcus have earlier been classified as streptococci and, thus, they are closely related. S. canis is closely related to S. pyogenes.|
|Comment:||Belongs to Lancefield's group G streptcocci.|
|New names of taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
