Abstract

An anti-TSST-1-specific monoclonal antibody (MAb 8-5-7) was tested for its protective capacity in a rabbit infection model to toxic shock syndrome (TSS). The challenge strain of Staphylococcus aureus (RN4710), which contained a plasmid encoding TSS toxin-1, was introduced into previously implanted chambers. Purified monoclonal antibody (1.25 mg of immunoglobulin G) administered parenterally 1 day before and 1 day after initiation of infection provided complete protection against the TSS-like syndrome and the mortality which occurred in unprotected rabbits.

摘要

一种抗中毒性休克综合征毒素-1(TSST-1)特异性单克隆抗体(单克隆抗体8-5-7)在兔感染模型中针对中毒性休克综合征(TSS)的保护能力进行了测试。将含有编码TSS毒素-1质粒的金黄色葡萄球菌攻击菌株(RN4710)引入先前植入的腔室。在感染开始前1天和开始后1天经肠胃外给予纯化的单克隆抗体(1.25mg免疫球蛋白G),可完全预防未受保护兔子中出现的TSS样综合征和死亡。
