Serum opsonic activity against zymosan was found to be decreased more markedly in highly diluted O type serum than in the other 3 types, among which no difference was noted. Heat-killed bacteria were equally well opsonized with any type of serum. This peculiar activity of O type serum against zymosan was not affected by the removal of isohemagglutinins. No inhibitory activity was demonstrable in O type serum.
研究发现，针对酵母聚糖的血清调理活性在高度稀释的O型血清中比在其他三种血型血清中下降得更显著，而其他三种血型血清之间未观察到差异。热灭活细菌在任何血型血清中都能被同样良好地调理。O型血清针对酵母聚糖的这种特殊活性不受同种血凝素去除的影响。在O型血清中未发现抑制活性。
