Morphological difference between eggs from resistant strain and susceptible strain. (A) Eggs from resistant strain parasites, showing morphology alterations, smaller size, and smaller lateral spines (10x); (B) Eggs from resistant strain, in a bigger scale, showing morphology alterations, smaller size, and smaller lateral spines (40x); (C) Eggs from susceptible strain parasites, showing normal morphology (10x); (D) Eggs from susceptible strain parasites, showing normal morphology, in a bigger scale (40x).
