Abstract: The inventive subject matter includes an antimicrobial peptide vectored composition made of a bacterial protein expression vehicle expressing one or more recombinant antimicrobial peptide effector molecules. More specifically these novel recombinant antimicrobial peptide effector molecules exhibit preferential antimicrobial activity. In some embodiments, the antimicrobial activity is facilitated via interaction with the lipid bilayer of the parasitic cell form, leading to membrane pore formation and resulting in cell lysis. The utility of the current inventive subject matter has demonstrated a reduced viability of Eimeira acervulina sporozoites was shown in vitro using a sporozoite killing assay.
