S. equi is a clonal descendent or biovar of an ancestral S. zooepidemicus strain with which it shares greater than 98% DNA homology and therefore expresses many of the same proteins and virulence fact...
متن کاملThe Classification of Hemolytic Streptococci
1. The hemolytic variety of streptococcus is homogeneous, consisting of members that are nearly identical. 2. This homogeneity is most strikingly displayed in the behavior of these streptococci in the complement fixation reaction, all the strains studied reacting in a nearly identical way with all the antisera.
متن کاملThe Leukotoxic Action of Streptococci
FOLLOWING PHAGOCYTOSIS OF CERTAIN STREPTOCOCCI HUMAN NEUTROPHILS UNDERGO A RAPID DISINTEGRATION: the leukotoxic reaction. Monocytes and eosinophils are similarly injured, as are polymorphonuclear cells of rabbit and guinea pig blood. The leukotoxic injury is not produced by culture filtrates of leukotoxic cocci nor does it follow phagocytosis of heat-killed cocci. The leukotoxic effect does not...
