In vitro tests of natural allelic variation of innate immune genes (avian β-defensins) reveal functional differences in microbial inhibition
Allelic variation in immune genes might result from, and contribute to, host-pathogen evolution. Functional allelic variation in the innate immune system has received little attention. Here, we investigate whether naturally occurring allelic variation within the avian innate immune system (β-defensins) is associated with variation in antimicrobial activity. We tested differences in in vitro antimi
