Description and significance
Streptococcus zooepidemicus is one of the two subspecies of Streptococcus equi; it is suggested to be the species from which subspecies equi has been derived (5). Subspecies zooepidemicus is a normal bacterial flora in horses. It is isolated from wound infections of horses, and it has been isolated from other mammals such as cows, rabbits, and swine (3). In some cases, subspecies zooepidemicus is also isolated from humans through throat swabs (4). It occasionally causes human infection that can be traced back to contact with horses or consumption of unpasteurized dairy products (4).
Like other streptococci, Streptococcus zooepidemicus is a non-motile, non-sporulating, encapsulated, gram-positive, catalse-negative, and coccoid bacterium. It is a beta hemolytic streptococcus that produces hyaluronic acid but not streptolysin O and occurs in pairs or long chains (2). It is also lactose positive and is capable of fermenting sorbitol but not trehalose (3, 28).
