The specific IgG antibody levels of mice immunized with rTspst assayed by ELISA using different antigens. The optical density (OD) values shown for each group are the mean ± standard deviation (SD) of antibody levels (n = 10). Asterisks (*) indicate statistically significant differences (P < 0.01) in OD values of ES antigens compared to rTspst or crude antigens.
