Protective Effect of a Prime-Boost Strategy with the Ts87 Vaccine against Trichinella spiralis Infection in Mice

Figure 6

Protection elicited by immunization with different vaccination regimens. The larvae per gram muscle (LPG) were counted in the muscles of mice 6 weeks after a challenge with 400 T. spiralis larvae. The mice immunized with the DNA-prime/protein-boost (DNA + P) displayed a 46.1% reduction in the muscle larval burden compared to the groups immunized with the homologous DNA prime-boost (36.2%, ) and homologous protein prime-boost (24.6%, ). . . The results are presented as the mean ± SE for 6 mice per group.
