Interpretive Summary: Virulent strains of the bacteria Aeromonas hydrophila have been implicated in severe disease outbreaks in commercial catfish culture, leading to rapid and substantial losses of large catfish in affected ponds. A team of scientists from Mississippi State University, Auburn University, and USDA-ARS-Warmwater Aquaculture Research Unit used first- and second- generation DNA sequencing technologies to produce a reference genome sequence assembly of the AL06-06 strain of A. hydrophila, which was isolated from goldfish. This genome sequence permits comparative genomic analyses with the ML09-119 strain of A. hydrophila that is implicated in acute disease outbreaks in adult pond-raised catfish. Our ultimate aim is understand virulence and environmental adaptations of this species in order to develop diagnostics and therapeutants to reduce catfish production losses due to A. hydrophila infection.

Technical Abstract: Aeromonas hydrophila occurs in freshwater environments and infects fish and mammals. In this work, we report the complete genome sequence of Aeromonas hydrophila AL06-06, which was isolated from diseased goldfish and is being used for comparative genomic studies with A. hydrophila strains causing bacterial septicemia in channel catfish aquaculture.
