Bermuda grass pollen allergen implicated in clinically relevant cross-reactivity to multiple grains: A case report.

In Korea, Bermuda grass is rarely seen and is generally found in athletic fields or theme parks. Following exposure to this relatively rare grass, our patient exhibited new anaphylactic responses to various external antigens. Therefore, we attribute his severe anaphylaxis to sensitization caused by Bermuda grass exposure and cross-reactive hypersensitivity to other grains.
