The aim of the present study was to determine the proportions of crossreactions between plant-pollen allergens.
The study which involved the Student test and a statistical analysis of samples taken from 680 allergic patients revealed a cooccurrence of positive skin-test reactions to summer pollen allergens of the following plants: various combinations of grass, trees, decorative flowers, oat grass, timothy grass, ash-tree, willow, meadow grass, common orchard grass, wheat, birch, tussock grass, rye-grass, soft grass, hazel, white poplar, golden rod, red fescue, rye, alder, linden, maple, and acacia.
The coefficients of the positive skin-test correlations have shown the respective variations of 0.3-0.7 (between different grasses), 0.01 (trees and grasses), 0.002 (trees and cereals), and 0.04 (different trees). The detailed correlation data have been presented in tabular form.
Distinct crossreactions have been found to occur between different grasses and cereals. Tree pollens fail to show crossreactions not only with pollens of other summer plants but with pollens of other trees as well.
