SEM findings of cultured T. spiralis larvae. (A) Normal cultured T. spiralis larva trunk without any effect of any drugs or chemicals showing the normal architecture of the cuticle annulation or transverse fissures (Tf) (yellow arrows) and longitudinal fissures (Lf) with the presence of bacillary openings (b) (red arrows). (B) Albendazole-treated cultured T. spiralis larva trunk showing mild smoothing of the cuticle annulation and transverse ridges (Tr) (yellow arrows) with the presence of multiple longitudinal fissures (Lf) and transverse fissures (Tf) of the cuticle (green arrows). (C) Eugenol-treated cultured T. spiralis larva trunk showing complete loss and deformities in the cuticle annulation and transverse ridges (Tr) (yellow arrows) and an area with multiple blebs (bl) and vesicles (V) of the cuticle (green arrows).
