Toxocara canis (T. canis, also known as dog roundworm) is a worldwide-distributed helminth parasite that primarily infects dogs and other canids, but can also infect other animals including humans. [ 1 ] [ 2 ] The name is derived from the Greek word toxon 'bow, quiver' and the Latin word caro 'flesh'. [ 3 ]
At about 5–15 mm, the worms are only about one-tenth the length of roundworms, have a hook-shaped angled front end (hence the name "hookworm") and a large mouth capsule with cutting plates. Females of A. caninum release eggs about 65×40 μm in size, which already have 4-10 furrowing stages at deposition.
Toxocariasis is an illness of humans caused by the dog roundworm (Toxocara canis) and, less frequently, the cat roundworm (Toxocara cati). [1] These are the most common intestinal roundworms of dogs, coyotes, wolves and foxes and domestic cats, respectively. [2]
Ancylostoma caninum is a species of nematode known as a hookworm, which principally infects the small intestine of dogs. [1] [2] [3] The result of A. caninum infection ranges from asymptomatic cases to death of the dog; better nourishment, increasing age, prior A. caninum exposure, or vaccination are all linked to improved survival.
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.
Trichuris vulpis is a whipworm that lives in the large intestine of canines in its adult stages. Out of different types of worms, Trichuris vulpis is one of the smaller worms with a size ranging from 30–50 mm in length. As the name suggests, the worm has a whip-like shape with distinct features including a small, narrow anterior head, which ...
Cestoda is a class of parasitic worms in the flatworm phylum (Platyhelminthes). Most of the species—and the best-known—are those in the subclass Eucestoda; they are ribbon-like worms as adults, commonly known as tapeworms. Their bodies consist of many similar units known as proglottids—essentially packages of eggs which are regularly shed ...
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.
