Toxocara canis

A number of various vertebrates, including humans, and some invertebrates can become infected by Toxocara canis.

In adult dogs, the infection by Toxocara canis is usually asymptomatic but can be fatal in puppies.

The incubation period for Toxocara canis and cati eggs depends on temperature and humidity.

Baylisascaris procyonis, the raccoon parasite, is related to the canine roundworm Toxocara canis.

Toxocara canis (also known as dog roundworm) is worldwide-distributed helminth parasite of dogs and other canids.

Dogs and foxes are the reservoir for Toxocara canis, but puppies and cubs pose the greatest risk of spreading the infection to humans.

Pet droppings contain eggs of Toxocara canis and Neospora caninum parasitic worms.

Extracts of the plant using methanol have shown larvicidal activity against the second stage larvae of dog roundworms (Toxocara canis).

For a start, there is growing public concern about the effects of toxocariasis, the disease transmitted by the roundworm Toxocara canis, carried in the faeces of un-wormed dogs.

Visceral larva migrans (human toxocarosis), a parasitary human disease due by Toxocara cati or Toxocara canis.

Toxocara canis and Toxocara cati are perhaps the most ubiquitous gastrointestinal worms (helminths) of domestic dogs and cats and foxes.

DUSN may be caused by a helminthic infection with Toxocara canis, Baylisascaris procyonis, or Ancylostoma caninum.

Infectious pathogens such as Mycobacterium tuberculosis, visceral larva migrans (Toxocara canis & Toxocara cati) can also cause retinal vasculitis.

Dog droppings are one of the leading sources of E. coli (fecal coliforms) bacterial pollution, Toxocara canis and Neospora caninum helminth parasite pollution.

Cats are normally the only hosts of Toxocara cati and dogs and foxes are normally the only hosts of Toxocara canis.

Many puppies are infected at birth with the roundworm Toxocara canis and so must be wormed frequently on a vet s advice for the first six months of life, and regularly thereafter.

The most common nematode species found in fox guts are Toxocara canis and Uncinaria stenocephala, Capillaria aerophila and Crenosoma vulpis, the latter two infect their lungs.

Both Toxocara canis and Toxocara cati eggs require a several week incubation period in moist, humid, weather, outside of a host before becoming infective, so fresh eggs cannot cause toxocariasis.

A 2007 study announced an ELISA specific to Toxocara canis, which will minimize false positives from cross reactions with similar roundworms and will help distinguish if a patient is infected with T. canis or T. cati.

Intimate contact with pets which have been in contact with contaminated soil may result in infection, while pets which are infested themselves by a different type of roundworm can cause infection with that type of worm (Toxocara canis, etc.) as occasionally occurs with groomers.

Though this term was originally applied to invasion of the visceral tissues of an animal by parasites whose natural hosts were other animals, it has now, in common usage, come to represent this type of invasion in humans alone and, in particular, by the larvae of Toxocara canis.

Humans are usually not infected with T. leonina; however, this parasite has been found in humans in a few instances and is a cause of visceral larva migrans in children, though less frequently implicated than is Toxocara canis, the most common roundworm parasite found in dogs.
