Protective Effect of a Prime-Boost Strategy with the Ts87 Vaccine against Trichinella spiralis Infection in Mice
The total secretory IgA in the intestinal washes of vaccinated mice measured by sandwich ELISA. The IgA level was increased in the mice immunized with the DNA-prime/protein-boost (DNA + P) compared to those immunized with rTs87 (P + P) or PBS (). The IgA level was significantly higher in mice with the DNA prime-boost (DNA + DNA) compared with the DNA-prime/protein-boost (DNA + P) (). . . The results are presented as the mean ± SE for 6 mice per group.
