近年来,B族链球菌(GBS)已被公认为是围产期的主要病原体。与其他包囊细菌一样,保护性免疫似乎与每种血清型的同源荚膜多糖抗原特异性血清抗体相关。由于幼儿对播散性GBS感染的易感性与母体血清中的类型特异性抗体缺乏有关,因此已提出用纯化的GBS类型特异性多糖免疫妇女作为通过胎盘运输保护性抗体预防婴儿疾病的方法。从GBS候选天然多糖已被纯化,免疫化学和结构特征,并作为免疫原在健康的成年志愿者。天然Ia、II和III型多糖已被证明分别在约65%、95%和70%的非免疫成人中无毒、安全和具有免疫原性。在先前免疫的志愿者中,对免疫的抗体应答接近100%。针对这些候选多糖疫苗的疫苗诱导的类型特异性抗体促进体外调理吞噬作用,保护给予同源生物体的致命攻击的动物,并且主要是IgG同种型。一旦在妊娠后半期免疫的妇女中记录到类似的结果,则应评估这些候选GBS多糖疫苗预防新生儿和幼儿GBS疾病的有效性。
In recent years group BStreptococcus(GBS) has been recognized as a major perinatal pathogen. As with other encapsulated bacteria, protective immunity appears to correlate with serum antibody specific for the homologous capsular polysaccharide antigen of each serotype. Since susceptibility of the young infant to disseminated GBS infection relates to type-specific antibody deficiency in maternal serum, immunization of women with purified GBS type-specific polysaccharides has been proposed as a method for the prevention of infant disease through placental transport of protective antibodies. Candidate native polysaccharides from GBS have been purified, immunochemically and structurally characterized, and employed as immunogens in healthy adult volunteers. Native type Ia, II, and III polysaccharides have been shown to be nontoxic, safe, and immunogenic in approximately 65%, 95%, and 70%, respectively, of nonimmune adults. Antibody response to immunization approaches 100% in previously immune volunteers. Vaccine-induced type-specific antibodies to these candidate polysaccharide vaccines promote in vitro opsonophagocytosis, protect animals given a lethal challenge of homologous organisms, and are predominantly of the IgG isotype. Once similar results can be documented in women immunized during the last half of pregnancy, efficacy of these candidate GBS polysaccharide vaccines in the prevention of neonatal and young infant GBS disease should be evaluated.
