Figure 7From: Protective immunity against Trichinella spiralis infection induced by TsNd vaccine in mice The number of intestinal adult worms (A) and larvae per gram (LPG) of muscles (B) recovered from vaccinated mice after a challenge infection with 300  T. spiralis larvae. Results are presented as the arithmetic mean ± standard deviation (SD) of ten mice each group. Asterisks (*) indicate statistically significant differences (P < 0.05) in worm recovery of the immunized group compared to empty plasmid pcDNA3.1 and PBS control groups.Back to article page
