Oral vaccination with recombinant Yersinia enterocolitica expressing hybrid type III proteins protects gerbils from amebic liver abscess

Infect Immun. 2004 Dec;72(12):7318-21. doi: 10.1128/IAI.72.12.7318-7321.2004.

Abstract

Protection against invasive amebiasis was achieved in the gerbil model for amebic liver abscess by oral immunization with live attenuated Yersinia enterocolitica expressing the Entamoeba histolytica galactose-inhibitable lectin that has been fused to the Yersinia outer protein E (YopE). Protection was dependent on the presence of the YopE translocation domain but was independent from the antibody response to the ameba lectin.
