Veterinary bacteriology: information about important bacteria
|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.|
|Micromorphology:||Nonmotile chain-forming cocci.|
|Gram +/Gram -:||G+|
|Other Enzymes:||Hippurate +, urease -|
|Biochemical Tests:||Voges-Proskauer -|
|Fermentation of carbohydrates:||
Other carbohydrates: Amygdalin ?, ribose +.
|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 names of bacterial phyla|
The taxonomic category phylum was previously not regulated by the International Code of Nomenclature of Prokaryotes (ICNP), but now this has changed and it was decided to revise the names of bacterial phyla. All phyla must be written in italics (which has been done on VetBact also before) and have the ending -ota.Published 2023-03-01. Read more...
|The taxonomy of chlamydias|
Species within the family Chlamydiaceae were previously divided into two genera Chlamydia and Chlamydophila. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned to the genus Chlamydia and this change has now been incorporated in VetBactPublished 2023-03-15. Read more...
