Serum opsonin, bacteria, and polymorphonuclear leukocyte interactions in subacute bacterial endocarditis
Year: 1968
Type: article
Abstract: The effect of anti-gamma-globulin factors on 7S gamma-globulin opsonins from patients with subacute bacterial endocarditis has been examined with a quantitative in vitro phagocytosis system. Human anti-gamma-globulin factors from patients with subacute bacterial endocarditis and rheumatoid arthritis inhibited the opsonic action of 7S gamma-globulin specifically bound to bacteria. A similar antiopsonic effect was obtained with rabbit antiserum to human gammaG globulin. The antiopsonic effect of anti-gamma-globulin factors did not correlate with their ability to potentiate agglutination of bacteria by 7S antibody. Competition was demonstrated between the antiopsonic effect of anti-gamma-globulin factors and the phagocytosis-promoting action of heat-labile serum factors containing hemolytically active complement.
