Interpretive Summary: Species of Aeromonas bacteria can cause septicemia in fish, and Aeromonas outbreaks have caused significant economic losses for catfish producers. We determined the genome sequence of a strain of Aeromonas veronii that was isolated from a diseased catfish. The bacteria demonstrated resistance to tetracycline, sulfamethoxazole-trimethoprim, florfenicol, and novobiocin. The genome analysis revealed several genes involved in drug resistance. The MS-18-37 genome sequence will be useful for comparative genomic analyses aimed toward more precise diagnostic assays and better understanding and alleviation of bacterial pathogenesis in fish culture systems.

Technical Abstract: Genus Aeromonas are Gram-negative bacteria, non-spore forming rods belonging to the family Aeromonadaceae within the class of Gammaproteobacteria. These facultative anaerobic bacteria are ubiquitous in aquatic environments and have a broad host range. We present here the complete genome sequence of multidrug-resistant A. veronii strain MS-18-37 isolated from diseased catfish. The genome size of this strain is 4,683,931, with a G+C content of 59.5%. Annotation reveals multiple genes which encode antibiotic resistant factors. The complete genome sequence of A. veronii strain MS-18-37 will provide a genetic basis for understanding the molecular mechanism of antimicrobial resistance.
