Humans are accidental hosts who become infected by ingesting infective eggs in contaminated soil or infected paratenic hosts. In pregnant female dogs, prenatal infection can occur, where larvae become mobilized at about three weeks prior to parturition and migrate through the umbilical vein to the lungs of the fetus, here molting into the L 3 stage just prior to birth. L 2 larvae may also be ingested by a variety of animals like mice or rabbits, where they stay in a dormant stage inside the animals’ tissue until the intermediate host has been eaten by a dog, where subsequent development is confined to the gastrointestinal tract.
