Under a variety of conditions of concentration, Eh, and pH, horse anti- serum and normal horse serum exerted similar bacteriostatic effects against Type A. Ferric iron abolished the bacteriostatic effect when added during the first 2 hours of incubation at Eh+60 mV. Ferrous iron abolished the bacteriostatic effect when added after 3 hours. Ferric iron abolished the bacteriostatic effect at—140 mV. A mixture consisting of horse β- and γ-globulins together with human transferrin exerted a bacteriostatic effect similar to that of whole serum. This system responded in the same way as whole serum to the addition of iron. A mixture of horse β- and γ-globulins exerted an immediate bactericidal effect which could not be prevented by ferric iron.
在多种浓度、氧化还原电位（Eh）和pH条件下，马抗血清和正常马血清对A型菌具有相似的抑菌作用。在Eh为+60 mV的条件下孵育的最初2小时内添加三价铁会消除抑菌作用。在3小时后添加二价铁会消除抑菌作用。在-140 mV时三价铁会消除抑菌作用。由马β球蛋白和γ球蛋白以及人转铁蛋白组成的混合物产生的抑菌作用与全血清相似。该系统对添加铁的反应与全血清相同。马β球蛋白和γ球蛋白的混合物产生即时杀菌作用，且这种作用不能被三价铁阻止。
