ABSTRACT
Objective To compare the immune protective effect of different antigens of Trichinella spiralis:excretory-secretory(ES) antigen of adult worms, ES antigen of muscle larva and their mixed antigens in mice. Methods ES antigens of Trichinella spiralis adult worms and muscle larva were produced by the physiological saline culture methods. The ES antigens of Trichinella spiralis adult worms, muscle larva and the mix were used to immunize mice 3 times at 7 day interval, adjuvant control and normal control were set up. Seven day after the final immunization, each mouse was orally challenged with 200 Trichinella spiralis larva. Intestinal adult worms and muscle larva of Trichinella spiralis of each group were recoveried and examined on Day 7 and Day 30 post-challenge,respectively. Results The intestinal adult worms of Trichinella spiralis reduced by 87.95%, 69.48% and 84.34% in the adult worm ES antigen group, muscle larval ES antigen group and their mixed antigen group, respectively, while muscle larva reduced by 74.79%, 87.97% and 86.87% respectively. Adult worm reduction rates of the adult worm ES antigen group and mixed antigen group were higher than those of muscle larval ES antigen group (P
