Antimicrobial Peptide Is Antagonistic to .

We identified an antimicrobial peptide (AMP) from that was antagonistic to . studies such as well-diffusion and field trials revealed that the AMP was active against . The field trials of AMP using -infected with a mannone oligosaccharide (MOS) prebiotic, antigens, -infected fish serum, , and cell free-supernatant (LABS-CFS) on an indicator organism further revealed that the antimicrobial agent could protect . . Other than the AMP, none of the above were able to eliminate the infectious agent , and were only able to delay the death rate for 3-4 days. Thus, we conclude that the AMP is antagonistic to and may be used for treatment of infections. Subsequent whole-genome sequence analyses enabled an understanding of the (probable) gene arrangement and its location on the chromosome. This information may be useful in the generation of recombinant peptides to produce larger quantities for treatment.
