title: Opsonic activity of anti-flagellar serum against Clostridium chauvoei by mouse polymorphonuclear leucocytes.
abstract: The role of anti-flagellar serum against Clostridium chauvoei in phagocytosis by mouse polymorphonuclear leucocytes was examined. Anti-flagellar serum markedly increased phagocytic rate against the flagellated strain Okinawa but not against a non-flagellated mutant (NFM) derived from the same strain, while anti-NFM serum increased the phagocytic rate against both strains. These results indicate that anti-flagellar serum exerts its protective effect by opsonic activity.
