Antibody to the capsular polysaccharide of Haemophilus influenzae type b (Hib) was not protective in infant rats depleted of complement by cobra venom factor (CoVF) even when serum antibody levels were many times the minimum protective level. Partial protection from Hib infection was achieved in CoVF-treated rats only if they were passively hyperimmunized with large doses of immunoglobulin G Hib capsular polysaccharide antibody. In addition, nonimmune CoVF-treated rats had higher mortality and blood bacterial density than nonimmune rats with intact complement systems.
针对b型流感嗜血杆菌(Hib)荚膜多糖的抗体,在被眼镜蛇毒因子(CoVF)耗尽补体的幼鼠中没有保护作用,即使血清抗体水平是最低保护水平的许多倍。只有当用大剂量免疫球蛋白G Hib荚膜多糖抗体对CoVF处理的大鼠进行被动超免疫时,才能实现对Hib感染的部分保护。此外,未免疫的CoVF处理大鼠比补体系统完整的未免疫大鼠具有更高的死亡率和血液细菌密度。
