“…A few authors report about human Toxocara infections due to eating raw or undercooked pork and chicken meat infected with the larvae (Taira et al, 2004). Still, the ingestion of infective eggs from contaminated soil or vegetables or from contact with cats and dogs is considered to be the most important route of human infection.…”

The aim of the study was to elucidate the distribution and possible transmission routes of Toxocara spp. infection in Estonia. Out of 454 faecal and sand samples collected from park lawns and sandpits in the town of Tartu, 19 were Toxocara positive (4.2%). Out of the 45 sandpit samples 17.8% were Toxocara positive. Cat faeces was found in 21 sandpit samples. Parasitological necropsies were performed on 41 euthanised stray dogs and 27 cats in the Tallinn Dog Home. Additionally, 13 wild free-roaming brown rats (Rattus norvegicus) were captured from the Tallinn Dog Home territory, necropsied and studied for the presence of Toxocara larvae. Toxocara canis adults were found in 14.6% of the dogs and Toxocara cati (syn. mystax) adults in the small intestines of 48.2% of the cats examined. Larval infection was detected in the kidney and liver in 5 dogs (12.2%). Our study demonstrated only low-level larval Toxocara infections in adult dogs. Toxocara larvae were not found in cats and brown rats. According to the results of this study, cats more often carry Toxocara infection than dogs. Under our conditions, stray and free-roaming cats are the main contaminators of the environment with Toxocara eggs. Children playing in sandpits are the main risk group for larval toxocarosis.

“…These parasites cannot develop into adult forms in humans and are restricted to larval forms, migrating through the soft tissues for months and even years and causing local or systemic inflammatory reactions in the affected organ. 4 Symptoms shown by infected persons depend on the organs affected and the magnitude of infection 5 resulting in several clinical forms of human toxocariasis. However, Smith and colleagues consider that human toxocariasis should be classified in three major forms: visceral larva migrans, ocular toxocariasis, and covert toxocariasis.…”

“…They are then swallowed and return to the intestine, where they become adults 1 . In paratenic hosts, the helminth never reach adulthood, but many larvae migrate to muscles, organs, and nervous tissue, where they can then become encysted 3,5 .…”

Introduction: Migration of Toxocara canis larvae was investigated in male and female Rattus norvegicus. Methods: Eighteen male and 18 female R. norvegicus were infected with 300 T. canis eggs. Three male and three female rats were euthanized at 3, 7, 10, 15, 30, and 60 days post-infection, and T. canis larvae were recovered by means of organ and tissue digestion. Results: Female rats showed a greater number of larvae in the liver than males. Conclusions: Paratenic host sex influences the migration pattern of T. canis larvae.
