Protection against Amoebic Liver Abscess in Hamster by Intramuscular Immunization with an Autographa californica Baculovirus Driving the Expression of the Gal-Lectin LC3 Fragment

Figure 2

Humoral anti-E. histolytica immune responses in AcNPV-LC3 intramuscular immunized and challenged hamsters. IgG antibodies in sera against total extract of E. histolytica trophozoites were measured by ELISA at day 0 (preimmune sera, black bars) and day 35, once finalizing the immunization protocol (postimmune sera, 7 days prior to intraportal challenge with trophozoites; white bars). Bars represent mean optical densities ().
