Toxocara cati, also known as the feline roundworm, is a parasite of cats and other felids. It is one of the most common nematodes of cats, infecting both wild and domestic felids worldwide. Adult worms are localised in the gut of the host.
Toxocara malayasiensis is a species of feline roundworm, a parasite which infects the intestine of cats. Feline roundworms are passed in the fecal matter of cats, and can be transmitted to humans, causing toxocariasis , a potentially serious disease.
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] Humans are among the many "accidental" or paratenic hosts of these roundworms. [3]
Both species of roundworm occur worldwide and roundworm infestation is a very common endoparasitosis. The adult roundworms, up to 10 cm long, live in the small intestine. The female worms produce a large number of eggs, which are released into the environment with the feces. The infective larvae develop in the eggs after about four weeks.
The name of the group Nematoda, informally called "nematodes", came from Nematoidea, originally defined by Karl Rudolphi in 1808, [22] from Ancient Greek νῆμα (nêma, nêmatos, 'thread') and -ειδἠς (-eidēs, 'species'). It was treated as family Nematodes by Burmeister in 1837. [22]
Ascaris is a nematode genus of parasitic worms known as the "small intestinal roundworms". [1] One species, Ascaris lumbricoides, affects humans and causes the disease ascariasis. Another species, Ascaris suum, typically infects pigs.
Feline diseases are often opportunistic and tend to be more serious in cats that already have concurrent sicknesses. Some of these can be treated and the animal can have a complete recovery. Others, like viral diseases, are more difficult to treat and cannot be treated with antibiotics, which are not effective against viruses.
