Abstract

The protozoan parasite Entamoeba histolytica causes extensive morbidity and mortality worldwide through intestinal infection and amebic liver abscess. Here we show that vaccination of gerbils, a standard model for amebic liver abscess, with recombinant proteins derived from the 170-kDa galactose-binding adhesin of E. histolytica and the serine-rich E. histolytica protein or a combination of the two recombinant antigens provides excellent protection against subsequent hepatic challenge with virulent E. histolytica trophozoites.

摘要

原生动物寄生虫溶组织内阿米巴通过肠道感染和阿米巴肝脓肿在全球范围内导致广泛的发病和死亡。在此我们表明,用源自溶组织内阿米巴170 kDa半乳糖结合粘附素和富含丝氨酸的溶组织内阿米巴蛋白的重组蛋白或这两种重组抗原的组合对沙鼠(阿米巴肝脓肿的标准模型)进行疫苗接种,可提供出色的保护,使其免受随后强毒溶组织内阿米巴滋养体的肝脏攻击。
