Seroprevalence in humans is 68% in Italy and 22% in France. The adult worms migrate mainly to the subcutis, but can invade all kinds of organs. [86] The dog plays a role in the spread of trichinellosis in only a few regions of the world. In China, the consumption of dog meat is an important source of infection for humans. [87]
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 ]
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]
Major groups of parasites include protozoans (organisms having only one cell) and parasitic worms (helminths). Of these, protozoans, including cryptosporidium, microsporidia, and isospora, are most common in HIV-infected persons. Each of these parasites can infect the digestive tract, and sometimes two or more can cause infection at the same time.
Body of female Angiostrongylus vasorum, detail of white genital strands wrapped around the digestive tract. 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.
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.
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 ...
Parasitic worms, also known as helminths, [1] are a polyphyletic group of large macroparasites; adults can generally be seen with the naked eye. Many are intestinal worms that are soil-transmitted and infect the gastrointestinal tract .
