Streptococcus zooepidemicus is a Lancefield group C streptococcus that was first isolated in 1934 by P. R. Edwards, and named Animal pyogens A. [1] It is a mucosal commensal and opportunistic pathogen that infects several animals and humans, but most commonly isolated from the uterus of mares.
Streptococcus equi subsp. zooepidemicus, prevalent in horses, is also present in guinea pigs, pigs, monkeys, and various other animals, including dogs, cats, ferrets, and birds. [15] Additionally, Streptococcus suis mainly affects suids but can be found in other animals like cattle, sheep, goats, and chickens, with different genotypes found in ...
Main Streptococcus groups are included as "Strep." at bottom left. In clinical practice, the most common groups of Streptococcus can be distinguished by simple bench tests, such as the PYR test for group A streptococcus. There are also latex agglutination kits which can distinguish each of the main groups seen in clinical practice.
The system, created by Rebecca Lancefield, was historically used to organize the various members of the family Streptococcaceae, which includes the genera Lactococcus and Streptococcus, but now is largely superfluous due to explosive growth in the number of streptococcal species identified since the 1970s.

Streptococcus species are the cause of opportunistic infections in poultry leading to acute and chronic conditions in affected birds. Disease varies according to the Streptococcal species but common presentations include septicaemia , peritonitis , salpingitis and endocarditis .
Streptococcus pyogenes is a species of Gram-positive, aerotolerant bacteria in the genus Streptococcus. These bacteria are extracellular , and made up of non-motile and non-sporing cocci (round cells) that tend to link in chains.
Horses that develop purpura haemorrhagica usually have a recent history of strangles (infection with Streptococcus equi subsp. equi) or vaccination (intramuscular or intranasal) for strangles. It is thought to be caused by an auto-immune reaction where antibodies against the S. equi M- or R-protein cross-react with proteins on endothelial cells .
