Interpretive Summary: Commercial catfish production is often limited by excessive mortalities caused by microbial infection. In order to increase our capacity for detection of potential pathogens, scientists at Mississippi State University, University of California, Davis, and USDA, ARS in Stoneville, Mississippi sequenced the genomes of two Franciscella marina species that were isolated from disease outbreaks in snapper. These bacterial isolates contained genetic elements associated with pathogenicity in other species. The data adds to our knowledge of fish pathogens and potental mechanisms of pathogenicity to fish species.

Technical Abstract: In 2015 and 2016, a previously unrecognized Francisella sp. was isolated from disease outbreaks in maricultured spotted rose snapper (Lutjanus guttatus) on the Pacific coast of Central America. Polyphasic analysis demonstrated these bacteria differed from any known Francisella spp. Herein, the complete genomes from the recently described Francisella marina are released.
