A Intestinal adult worms; B The in vitro NBL production of each female adult at 72 h; C Larvae per gram (LPG) of muscles. The worm numbers are shown as the mean ± SD from TsDNase II-immunized mice, pcDNA 3.1 and PBS control mice (n = 10). The significant difference was *P < 0.001.Back to article page
