Interpretive Summary: The bacterium, Pseudomonas mosselii Gil3, was isolated from the gill tissue of a channel catfish that survived from lethal challenge of virulent Aeromonas hydrophila (vAh). P. mosselii Gil3 showed antagonist effect against in in vitro assays. To explore the potential of P. mosselii Gil3 as a probiotic against vAh, we sequenced the genome of this bacterium. Initial analysis showed that the gonome of P. mosselii Gil3 encodes not only numerous aromatic metabolism pathways but also proteins for biosynthesis of antimicrobial compounds.

Technical Abstract: Pseudomonas mosselii Gil3 was isolated from a catfish that survived from lethal challenge with hypervirulent Aeromonas hydrophila (vAh). When assayed in vitro, the bacterium showed antagonism against vAh. Sequence analysis revealed that the genome of P. mosselii Gil3 encodes numerous aromatic metabolism pathways and proteins for biosynthesis of antimicrobial compounds.
