Immunization with different A. suum extracts had distinct effects on pulmonary inflammation following A. suum infection. Determination of pulmonary injury and inflammation by analysis of pulmonary (A) Score of inflammation; (B) Morphometry of total area of inflammation; and (C) Histopathological visualization of the lesion caused by larval migration in the lungs, perivascular edema (arrow), peribronchial cell infiltrate (red arrowhead), larvae occupying the lumen of the bronchi and bronchioles (asterisk), hypertrophy and hyperplasia of bronchial epithelial (arrowhead), mucous plug obstructing the bronchus (hashtag). Stained by H&E, 10x (bar = 100 μm) and 40x (bars = 50 μm) magnification. The statistically significant differences (p < 0.05) were represented by the ^* in comparison with the control group MPLA in which ^*p < 0.05, ^**p < 0.01, ^***p < 0.001.
