Human toxocariasis is a zoonotic parasitic disease caused by the larva of toxocara canis or cati. It is one of the most commonly reported zoonotic helminth infection in the world. Human are infected mainly by the accidental ingestion of embryonated eggs due to the pica, geophagia, the consumption of contaminated raw vegetables and poor personal hygiene particularly in childhood. In adults, the consumption of raw meat from potential paratenic hosts e.g. chickens, lambs, rabbits and dogs is a major cause of human toxocariasis. The larva can reach various organs such as the liver, lung, brain, and eye by the hematogenous spread and cause visceral larva migrans. We experience a case of pulmonary infiltration with eosinophilia by visceral larva migrans after eating the raw liver and kidney of a dog.

This study describes the isolation of a Toxocara canis species-specific excretory-secretory(ES) antigen and the development of an enzyme-linked immunosorbent assay(ELISA) based on this antigen. Analysis of the ES antigens of T. canis, Toxocara vitulorum, Ascaris lumbricoides and Necator americanus larval antigen was performed by SDS-PAGE followed by western blotting. A 57 kDa T. canis-specific antibody fraction(TcES-57) was identified by western blotting and labelling with anti-Toxocara antibodies(from experimental rabbits and human patients) and tracing with anti-human or anti-rabbit peroxidase conjugate. No protein fraction of 57 kDa was detected in ES or larval antigens collected from T. canis, T. vitulorum, A. lumbricoides and N. americanus. Using TcES-57, a specific anti-serum was produced in rabbits and a double sandwich ELISA was developed. This test was validated using known seropositive sera from toxocariasis patients, sera from A. lumbricoides or N. americanus patients, and 50 serum samples from cats. These tests revealed that TcES-57 antigen is specific to T. canis infection and does not cross react with sera of other related infections. Thus, ELISA based on TcES-57 antigen was proven to be an effective tool in the diagnosis of toxocariasis and studies on the role of T. canis in the epidemiology of human toxocariasis.
