Eggs reach the digestive tract of the rabbit, and after hatching, the oncospheres migrate to various organs, resulting in granulomatous lesions or giving rise to the phase of cysticerci or metacestode, that are mainly housed in the peritoneal cavity.

After ingestion of the egg, the embryo (oncosphere) hatches, penetrates the intestinal mucosa, enters into the host's circulatory system (via venous and lymphatic pathways), and develops into the characteristic vesicular metacestode when reaching a suitable anatomical site, assuming the intermediate host's immune system is unable to destroy the oncosphere [1].
