Interpretive Summary: Species of Aeromonas bacteria can cause septicemia in fish, and Aeromonas outbreaks have caused significant economic losses for catfish producers. In order to provide comparative genomic information between Aeromonas species, we sequenced the genome of a strain of Aeromonas bestiarum, GA97-22, that was pathogenic in rainbow trout. The genome analysis revealed a Type 3 secretion system unique to this strain that was not seen in the reference A. bestiarum genome sequence. The GA97-222 strain also contained a Type VI secretion system not found in two other pathogenic Aeromonas species. The GA97-22 genome sequence will be useful for comparative genomic analyses aimed toward better understanding and alleviation of bacterial pathogenesis in fish culture systems.

Technical Abstract: Aeromonas bestiarum is a Gram-negative mesophilic motile bacterium causing acute hemorrhagic septicemia or chronic skin ulcers in fish. Here, we report the draft genome sequence of A. bestiarum strain GA97-22 isolated from rainbow trout in 1997. This genome sequence will improve our understanding of the complex taxonomy of motile aeromonads.
