Figure 3From: Protective immunity in mice vaccinated with a novel elastase-1 significantly decreases Trichinella spiralis fecundity and infectionLevels of total intestinal sIgA (A) and TsE-specific sIgA (B) in intestinal washing of vaccinated mice. The data are shown as the mean OD values ± SD for 10 mice per group. TsE-specific sIgA was undetectable in mice injected with only ISA 201 or PBS. The vaccination time is indicated as an arrow (↑). *P < 0.0001 compared with PBS and ISA 201 adjuvant group.Back to article page
