Notably, molecular characterization of the metacestode
stage from 1 of the southern Ontario dogs diagnosed with AE without travel history was consistent with E.

Here, the oncosphere develops into the metacestode
(hydatid cyst) (1).
In Vivo Efficacy of Nigella Sativa Aqueous Seed Extract Against Metacestode
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.
Taenia solium metacestode
immunodominant peptides recognized by IgG antibodies in cerebrospinal fluid and serum paired samples from patients with active and inactive neurocysticercosis.
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 .
Hydatid disease may be caused when the tapeworm Echinococcus goes through its metacestode
stage to form larvae.

(cysticerci)," Molecular and Biochemical Parasitology, vol.
Finally, the rise in levels of the analyte after 1-2 months seems to indicate, at least for some patients, either the metastatic spread to other tissues and organs of metacestode
, or the regrowth of the larva in the same site.
These segmented worms are characterized by an indirect life cycle with production of encysted larvae (metacestode
) in intermediate host tissues and transmission to the final host via feeding on infected tissues.
