in the bloodstream and can lay dormant for years.
Cotylurus flabelliformis may also penetrate snails of Planorbidae and Physidae, but only if they are infected by other species of trematodes, where its encysts
within sporocysts and/ or rediae (Cort, Olivier, & Brackett, 1941).
The trophozoite or ameboid form encysts
under unfavorable circumstances and converts to a temporary biflagellate form if exposed to high temperatures.
The trematode encysts
in the lamellae of gills of the intermediate fish-host and may result in significant damage of gills and depressed respiratory function at high rates of metacercarial infection (Blazer and Gratzek, 1985; McDonald et al.
The hosts ingest the eggs, and the first instar larva hatches within their intestines, penetrates the mucosa, and retreats into the tissue, where it encysts
and molts to the third larval stage.
We sent her on her way again with enough fenbendazole wormer to prevent the puppies in the womb from being infected by a roundworm which cleverly encysts
in the muscle of the bitch, migrating to the womb in late pregnancy.
In crustaceans the parasite encysts
in muscles and internal organs.
It burrows the intestinal wall and encysts
in muscular tissues.
