Light microscopic appearance of carmine-stained adult worms recovered from FSm14/29-immunized mice. (A) Abnormally shortened adult male worm exhibiting multiple gut dilatations (Gd). The testes were not clearly seen due to dilatations of the gut in the anterior part of the worm. (B) Slightly elongated male with bulging (arrow) in the posterior end. (C&D) Male worm demonstrating gut dilatation which hides the appearance of the testes, with ill-defined oedematous suckers, and remarkable tegumental irregularities in the worm outline. (E) An example of an elongated female. (F&G) Posterior ends of females possessing universal pronounced tegumental oedematous irregularities (arrows) or even wrinkled posterior ends. (H) Occasional swollen knots (Kn) in a female mid-body. Sparseness of the pigment content of the gut was noticed in all examined female worms with indistinct vitelline gland lobulations and ill-defined ovarian boundaries.
