Cross-reactivity among five major pollen allergens.

Abstract

We have studied the cross-reactivity between L. perenne, S. cereale, P. pratense, C. dactylon, and Ph. communis. The results obtained demonstrate that L. perenne, S. cereale, and P. pratense have strong cross-reactivity. C. dactylon has a number of allergens that cross-react with the rest of the grasses studied but they are minor allergens. Ph. communis possesses a moderate cross-reactivity with the species of the group but it has, as well, individual allergens.
