[Toxocariasis: under-estimated disease. Report of 9 cases].

: Toxocariasis or visceral larva migrans is a parasitosis due to the migration in the human organism of animal ascarid larvae. Its importance is under-estimated and the reported tunisian cases are rare. We report nine cases of toxocariasis, noted between January of 2000 to March of 2002, in the laboratory of parasitology-mycology in La Rabta Hospital. They were six children and three adults. The clinical forms are varied: ophthalmologic form (5 cases), general syndrome (1 case), oedema (1 case) and hypereosinophilia (2 cases), and confirmed serologically by the presence of anti Toxocara canis antibody using ELISA test. Visceral larva migrans should be kept in mind to avoid severe forms such as ophthalmologic forms.
