1.C.116 The Membrane-permeabilizing Peptide, Abaecin (Abaecin) Family 

Honeybees (Apis mellifera) are frequently exposed to and infected by plant-associated bacteria. They produce antibacterial peptides which accumulate in the bee hemolymph. One such peptide, abacin, exhibits a broad spectrum of  activities against Gram-negative plant pathogens. The highest specific activity was against an apidaecin-resistant Xanthomonas strain. In contrast to the immediate action of apidaecins, bactericidal activity is delayed (Casteels et al. 1990).
