Protective Effect of a Prime-Boost Strategy with the Ts87 Vaccine against Trichinella spiralis Infection in Mice
rTs87-specific total IgG and subtype IgG1 and IgG2a levels detected in the sera of immunized mice. The mouse sera were collected two weeks after the 3rd immunization and were measured by ELISA. The rTs87-specific total IgG is shown as the geometric mean titers within the group (Figure 1(a)). . The subtype IgG1 and IgG2a levels are shown as the mean absorbance values ± SE.
