O modelo de estudo foi seccional. Humans are infected, like other paratenic hosts, by ingestion of embryonated T. When goxocara the serologic findings, clinicians must be aware that a measurable titer does not necessarily indicate current clinical Toxocara canis infection. Toxocariasis is caused by larvae of Toxocara canis dog roundworm and less frequently of T.
The adult worm was never identified in this case. Encysted stages are reactivated in female dogs during late pregnancy and infect by the transplacental and transmammary routes the puppiesin whose small intestine adult worms become established. In this parasitic disease the diagnosis does not rest on identification of the parasite. Diagnosis is usually made by serology or the finding of danis in biopsy or caanis specimens. The worm was never identified, but the egg size is most consistent with T.

L 2 larvae may also be ingested by a variety of animals like mice or rabbits, where they stay in a dormant stage inside the animals’ tissue until the intermediate host has been eaten by a dog, where subsequent development is confined to the gastrointestinal tract.
The larvae encyst in gut wall tissues within otxocara dogs.

Since the larvae do not develop into adults in humans, a stool examination would not detect any Toxocara eggs. Humans are accidental hosts who become infected by ingesting infective eggs in contaminated soil or infected paratenic hosts. Adult worms of the dog roundworm Toxocara canis live in the gut of dogs, puppies and other canids.

Toxocara eggs are subspherical, thick-shelled and have a pitted surface.
Institute of Biology and the British Society for Parasitology; As paratenic hosts, a number of vertebratesincluding humans, and some invertebrates can become infected. Antibody reactivity in human toxocariasis.
A certain amount of the female dog’s dormant larvae penetrate into the intestinal lumen, where molting into adulthood takes place again, thus leading to a new release of eggs containing L 1 larvae.
The life cycle is completed when dogs eat these hosts and the larvae develop into egg-laying adult worms in the small intestine. Treatment Information Treatment Information Treatment information for toxocariasis can be found at: Regular deworming by a veterinarian is important to stop canine re-infections, especially if the dog is frequently outdoors.

Toxocara toxocafa larva beginning to hatch. In older dogs, patent infections can also occur, but larval encystment in tissues is more common. These inherent problems result in underestimations of sensitivity and specificity.
