Toxoplasmosis presents as a congenitally or postnatally contracted infection whereas toxocariasis is always an acquired disease.

What is the infective stage of Toxocara canis?

In the environment, eggs embryonate and become infective. 3. After eggs are ingested by a dog, they hatch and release larvae, which penetrate the intestinal wall.

What is Toxocara parasite?

How does Toxocara canis accomplish its life cycle?

Life Cycle: Toxocara canis accomplishes its life cycle in dogs, with humans acquiring the infection as accidental hosts. Unembryonated eggs are shed in the feces of the definitive host . Eggs embryonate and become infective in the environment . Following ingestion by dogs , the infective eggs hatch and larvae penetrate the gut wall.

Where does Toxocara spp shed its eggs?

Toxocara spp. can follow a direct (one host) or indirect (multiple host) life cycle. Unembryonated eggs are shed in the feces of the definitive host (canids: T. canis; felids: T. cati) .

Are there any confirmed zoonotic species of Toxocara?

Confirmed zoonotic species include the dog roundworm T. canis (presumed most common) and the cat roundworm T. cati (frequency not known). It is not known whether other closely-related Toxocara species can infect humans (e.g. T. malaysiensis of cats). Toxocara spp. can follow a direct (one host) or indirect (multiple host) life cycle.

How are Toxocara cati Larvae transmitted to cats?

In cats, T. cati larvae can be transmitted via the transmammary route to kittens if the dam is infected during gestation, but somatic larval arrest and reactivation does not appear to be important as in T. canis. Toxocara spp. can also be transmitted indirectly through ingestion of paratenic hosts.
