In animals, these symptoms can include fever, inflammation of thorax, lymph nodes, or abdomen, bronchopneumonia, sepsis, mastitis, and more. [12] In Horses, S. zooepidemicus is normal flora bacterium, but is opportunistic and therefore will infect wounds, the respiratory system, and uterine, if given the chance. In horses, which are most ...
Strangles (also called equine distemper) is a contagious upper respiratory tract infection of horses and other equines caused by a Gram-positive bacterium, Streptococcus equi. [1] As a result, the lymph nodes swell, compressing the pharynx , larynx , and trachea , and can cause airway obstruction leading to death, hence the name strangles. [ 2 ]
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 ...

Streptococcus equinus is a Gram-positive, nonhemolytic, nonpathogenic, lactic acid bacterium of the genus Streptococcus. [5] It is the principal Streptococcus found in the alimentary canal of a horse, [6] and makes up the majority of the bacterial flora in horse feces. [7] Equivalence with Streptococcus bovis has been contested. [4]
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 .
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.
