Abstract
Human toxocariasis is due to the larval stages of the Ascarids Toxocara canis (T. canis ) and probably Toxocara catis , common roundworm of dogs and cats respectively. Among the helminthiasis, toxocariasis is one of the most prevalent worldwide, especially in settings where man-soil-dog relationship is particularly close. Even if it tends to be more prevalent in tropical settings, seroprevalence in western countries ranges from 2.4% to 31.0%.
