What kind of bacterium is Streptococcus suis? Understanding the characteristics of this pathogen
Streptococcus suis belongs to the genus Streptococcus. The cells are round or oval, less than 2.0 mm in diameter, generally arranged in chains or in pairs, and stain Gram-positive. The colonies are small, grayish-white and translucent. Most pathogenic strains are capable of hemolysis. Streptococcus suis has 35 serotypes (1-34, 1/2) as well as some untypeable strains. Among them, the four serotypes 1, 2, 7 and 9 are highly pathogenic. Muramidase-released protein (MRP) and extracellular factor (EF) are
