Echinococcus granulosus, also called the hydatid worm or dog tapeworm, is a cyclophyllid cestode that dwells in the small intestine of canids as an adult, but which has important intermediate hosts such as livestock and humans, where it causes cystic echinococcosis, also known as hydatid disease.
Pigs and humans can act as intermediate hosts for the larval form, but humans are the only definitive hosts for the adult tapeworm. The larvae are cystic, fluid-filled sacs containing a tapeworm head (scolex) with four suckers and a double row of hooks, along with a narrow neck and a body made up of hundreds of segments called proglottids. When ...
Praziquantel has a serum half-life of 0.8 to 1.5 hours in adults with normal renal and liver function. Metabolites have a half-life of 4 to 5 hours. In patients with significantly impaired liver function (Child-Pugh score B and C), the serum half-life is increased to 3 to 8 hours. Praziquantel and its metabolites are mainly excreted renally ...
Echinococcus multilocularis, the fox tapeworm, is a small cyclophyllid tapeworm found extensively in the northern hemisphere. E. multilocularis, along with other members of the Echinococcus genus (especially E. granulosus ), produce diseases known as echinococcosis .
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 ...
The tapeworm eggs are present in the feces of a person infected with the adult worms, a condition known as taeniasis. [2] [8] Taeniasis, in the strict sense, is a different disease and is due to eating cysts in poorly cooked pork. [1] People who live with someone with the pork tapeworm have a greater risk of getting cysticercosis. [8]

Niclosamide's metabolic effects are relevant to a wide ranges of organisms, and accordingly it has been applied as a control measure to organisms other than tapeworms. For example, it is an active ingredient in some formulations such as Bayluscide for killing lamprey larvae, [ 11 ] [ 12 ] as a molluscide, [ 13 ] and as a general purpose ...
