Fruit flies normally produce two types of antimicrobial peptides (defensin and drosomycin).Mutant fruit flies were generated that produced no antimicrobial peptides,defensin only,or drosomycin only.Wild-type flies and the mutant flies were then tested for survival after infection with Neurospora crassa fungi or with Micrococcus luteus bacteria.The results are shown in Figures 35.1 and 35.2.

The results show that flies with no antimicrobial peptides are highly susceptible to both fungal and bacterial infections, while those with either defensin or drosomycin alone are partially protected. However, when only defensin or drosomycin is present, the flies are more resistant to bacterial and fungal infections, respectively. Therefore, we can conclude that the drosomycin gene protects flies from bacterial infections.
