|Species/Subspecies:||Streptococcus equi subsp. ruminatorum|
|Etymology:||Genus name: twisted (like a chain) coccus (coccus means a grain or a berry and referrs to any spherical microorganism).|
Species epithet: of horse.
Subspecies epithet: of ruminants.
|Significance:||[Of minor importance]|
|Type Strain:||Mt 167 = CCUG 47520|
|Macromorphology (smell):||Form non-pigmented, mucoid colonies after incubation for 24 h at 37°C on blood agar. The colonies give (clear) β-hemolysis on sheep blood agar.|

|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. equi consists of three subspecies, which are related to S. devriesei.|
|Comment:||Belongs to Lancefield's group C streptcocci.|
|New families introduced within the order Enterobacterales|
The order Enterobacterales (formerly called Enterobacteriales) previously consisted of bacteria with different properties and phylogenetically, these bacteria were far apart. In order for the taxonomy to be more in line with phylogeny, some of these bacteria have, therefore, been sorted into 6 new families.Published 2022-04-13. Read more...
