Serum-specific anti-rTspGST IgG level of mice vaccinated with rTspGST determined by ELISA with crude antigens of Trichinella spiralis various stages (AW at 3 and 6 dpi, NBL, ML and IIL) and ML ES antigens. The OD values shown for each group are the mean ± SD of the antibody levels from ten mice. Asterisks indicate statistically significant differences (*P < 0.01)
