[ 1 ] [ 2 ] The name is derived from the Greek word " toxon ," meaning bow or quiver, and the Latin word "caro," meaning flesh. [ 3 ]
The life cycle begins when L3 larvae are ingested by a definitive host, primarily the fox or dog. This can be through eating mollusc (intermediate hosts), frogs (paraentenic hosts), or from food infected with slime from the slugs or snails. The L3 larvae migrate to the mesenteric lymph nodes and molt to L4, and L5.
Dipylidium life cycle. Dipylidium caninum, also called the flea tapeworm, double-pored tapeworm, or cucumber tapeworm (in reference to the shape of its cucumber-seed-like proglottids, though these also resemble grains of rice or sesame seeds) is a cyclophyllid cestode that infects organisms afflicted with fleas and canine chewing lice, including dogs, cats, and sometimes human pet-owners ...
Andersonstrongylus milksi (syn. Filaroides milksi) is a rare member of the Filaroididae in dogs and is largely similar to Filaroides hirthi in appearance, life cycle, and clinical presentation. [36] The parasites cause small nodules in the area of the bifurcation of the trachea or in the lung tissue; dead worms can also cause larger granulomas.

Life cycle of the eucestode Taenia: Inset 5 shows the scolex, a disk with hooks on the end. Inset 6 shows the tapeworm's whole body, in which the scolex is the tiny, round tip in the top left corner, and a mature proglottid has just detached. [19] Life cycle of Diphyllobothrium latum relies on at least three hosts, crustaceans, fish, and humans ...
