associated with allergic responses. People with asthma are shown to have a higher prevalence of Toxocara seropositivity. Research suggests that the IgE production stimulated by infection with Toxocara may contribute to the onsets of allergic asthma in children. The effects of how parasite load, frequency of exposure, and influence of genetics affect this relationship between Toxocara infection and allergic asthma are still unknown, yet important in understanding how to prevent asthma and other atopic diseases around the globe.
