Interpretive Summary: Aeromonas hydrophila is ubiquitously found in aquatic environments and can cause motile aeromonad septicemia (MAS), a disease that can lead to significant losses of aquacultured catfish in the Southeastern United States. In order to identify variation in virulence genes and antigens of fish-pathogenic A. hydrophila, scientists at Mississippi State University have collaborated with USDA, ARS scientists at Stoneville, MS and Beltsville, MD to determine the genomic sequence of one strain of A. hydrophila isolated from a diseased catfish and two isolates from disease tilapia. The genomes from the new isolates varied in the number of predicted genes, predicted protein coding sequences, and number of transfer RNA sequences, and the average nucleotide identity with existing A. hydrophila genomes ranged from 96.94 to 99.99%. Comparisons of the new draft genomes with those of A. hydrophila isolated from catfish and goldfish will aid in the identification of virulence factors and development of vaccines or therapeutants for the reduction of catfish morbidity and mortality in commercial ponds.
Technical Abstract: Aeromonas hydrophila is a Gram-negative bacteria that is particularly adapted to freshwater environments and can cause severe infections in fish and humans. Here we report the draft genomes of three A. hydrophila catfish and tilapia isolates.
