|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.
[Of minor importance]
|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:||
Other carbohydrates: amygdalin -, ribose +
|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.|
