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 ...
Infections with Taeniidae other than the thick-necked tapeworm are rare in cats. The 30 to 150 cm long taenia pisiformis (main hosts: dogs, foxes) requires lagomorphs and rodents as intermediate hosts. Cats are a less suitable final host for this tapeworm; it is usually excreted by the cat before the formation of egg-containing (gravid) limbs.
A pair of tapeworm proglottids. Taenia taeniaeformis is a parasitic tapeworm, with cats as the primary definitive hosts. Sometime dogs can also be the definitive host. The intermediate hosts are rodents and less frequently lagomorphs (rabbits). The definitive host must ingest the liver of the intermediate host in order to acquire infection. [1]
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.
Taenia pisiformis, commonly called the rabbit tapeworm, is an endoparasitic tapeworm which causes infection in lagomorphs, rodents, and carnivores. Adult T. pisiformis typically occur within the small intestines of the definitive hosts , the carnivores.
Life cycle of T. canis. T. canis is an 8 to 18 cm long nematode that parasitizes (lives as a parasite) in the small intestine. There, the adult females release approximately 85 μm large unfurrowed eggs, whose shell is thick and rough (golf ball-like) and which are released into the outside world via the feces.
Eucestoda, commonly referred to as tapeworms, is the larger of the two subclasses of flatworms in the class Cestoda (the other subclass being Cestodaria). Larvae have six posterior hooks on the scolex (head), in contrast to the ten-hooked Cestodaria .
[3] [6] Finally, the second intermediate host is eaten by a definitive host. A couple of weeks later, S. erinaceieuropaei mature into adult tapeworms and the life cycle continues. Adult tapeworms can survive up to 30 years in their definitive host (typically dogs and cats). [1]
