Eosinophilia, lead poisoning and Toxacaris canis infection in children

This report identifies Toxacaris canis infestation as a frequent cause of eosinophilia in both lead-poisoned and nonlead-poisoned children. An overall prevalence of 23% was recorded. Literature reveals a vast difference in regional prevalence of T canis infestations and emphasizes the need for the practitioner to be aware of the community in which he/she practices. Because of the adverse neuropsychological effects from T canis infestations, doctors in areas where there is a high prevalence of the disease should consider screening for infestations and conducting psychological testing of infested children.
