Fig 4. Lung larva reduction (A) and stunted development (B) in mice immunized with rAs16 formulated with ISA720 on Day 8 after being challenged with 2,500 A. suum eggs.

Lung larvae are presented as the mean ± S.D (N = 15). The asterisks indicate statistically significant differences in larval reduction compared to the PBS or adjuvant control groups (*p< 0.05, ***p< 0.001). The larvae collected from lung Baermann culture were observed under 4x objective lens.
