| streptococcus equi | A species of gram-positive, coccoid bacteria isolated from abscesses in submaxillary glands and mucopurulent discharges of the upper respiratory tract of horses.

Synonym: Dick test toxin, erythrogenic toxin, scarlet fever erythrogenic toxin. (05 Mar 2000) |
| Streptococcus faecalis | A species found in human faeces and in the intestines of many warm-blooded animals; occasionally found in urinary infections and in blood and heart lesions in cases of subacute endocarditis; associated with European foul brood of bees and with mild outbreaks of food poisoning. (05 Mar 2000) |
