Species epithet: from loss of lactation
Subspecies epithet: see Species epithet.
|Type Strain:||ATCC 43078 = CCUG 27301|
||Small (approximately 1 mm in diameter) transluscent colonies after incubation for 24 h at 37°C on blood agar. Gives a weak (greenish), alpha-hemolysis on blood agar.|
|Micromorphology:||Nonmotile cocci in chains|
|Gram +/Gram -:||G+|
|Other Enzymes:||Esculinase v, hippuricase -, coagulase -|
|Biochemical Tests:||Voges-Proskauer -|
|Fermentation of carbohydrates:||
Other carbohydrates: Amygdalin ?, ribose +.
||SELMA- or SELMA Plus plates are used for cultivation of samples from suspected mastitis cases.|
|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. dysgalactiae is closely related to S. agalactiae.|
|Comment:||Belongs to Lancefield's group C streptcocci.|
