| streptococcus agalactiae | A bacterium which causes mastitis in cattle and occasionally in man. (12 Dec 1998) |

| streptococcus bovis | A species of gram-positive, coccoid bacteria commonly found in the alimentary tract of cows, sheep, and other ruminants. It occasionally is encountered in cases of human endocarditis. This species is nonhemolytic. (12 Dec 1998) |
| Streptococcus constellatus | A species found in tonsils, purulent pleurisy, appendix, the nose, throat, and gums, and infrequently on the skin and in the vagina. (05 Mar 2000) |

| 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. This organism belongs to group c streptococci with regards to antigen response and is known to cause strangles. The subspecies s. Zooepidemicus is also considered a pathogen of horses. (12 Dec 1998) |
| Streptococcus equinus | A species that is the predominant organism in the intestines of horses. (05 Mar 2000) |
| Streptococcus equi zooepidemicus | A species causing mastitis in cattle. (05 Mar 2000) |
| streptococcus erythrogenic toxin | A culture filtrate of lysogenised group A strains of beta-haemolytic streptococci, erythrogenic when inoculated into the skin of susceptible persons, and neutralised by antibodies that appear during scarlet fever convalescence; three immunological types (A, B, and C) are recognised. Synonym: Dick test toxin, erythrogenic toxin, scarlet fever erythrogenic toxin. (05 Mar 2000) |
| Streptococcus lactis | A species found commonly as a contaminant in milk and dairy products; a common cause of the souring and coagulation of milk; some strains produce nisin, a powerful antibiotic that inhibits the growth of many other Gram-positive organisms. (05 Mar 2000) |
| Streptococcus lactis R factor | 10-formylpteroic acid;a folic acid factor for certain bacteria. Synonym: SLR factor, Streptococcus lactis R factor. (05 Mar 2000) |
| Streptococcus M antigen | The somatic antigen associated with virulence and type specificity of group A streptococci. Synonym: M protein. (05 Mar 2000) |
| Streptococcus mitis | A species found in the human mouth, throat, and nasopharynx; ordinarily, it is not considered to be pathogenic, but this organism may be recovered from ulcerated teeth and sinuses and from blood and heart lesions in cases of subacute endocarditis. (05 Mar 2000) |
