摘要: Allergenic ragweed (Ambrosia spp.) pollen grains, after being released from anthers, can be dispersed by air masses far their source. However, the action of temperature, humidity and solar radiation on grains in atmosphere could impact ability long distance transported (LDT) to maintain allergenic potency. Here, we report that major allergen Ambrosia artemisiifolia (Amb a 1) collected ambient during episodes LDT still have immunoreactive properties. The amount Amb 1 found was not constant varied between episodes. In addition allergens sized particles, detected reactive subpollen respirable particles. These findings suggest potential cause allergic reactions, only heavily infested areas but, due episodes, also regions unaffected populations.
