Figure 8From: Protective immunity against Trichinella spiralis in mice elicited by oral vaccination with attenuated Salmonella-delivered TsSP1.2 DNAImmune protection of mice vaccinated with ∆cyaSL1344/pcDNA3.1-TsSP1.2 after being challenged with 300 T. spiralis larvae. A Intestinal adult worm number. B Larvae per gram (LPG) of muscles. Data are shown as the mean ± SD of 10 mice/group. A statistically distinct reduction was observed in the parasite burdens of intestinal adults and muscle larvae in immunized mice compared to plasmid alone or PBS group (*P < 0.01).Back to article page
