Abstract
|
|
|
|
Edwardsiella spp. is an important pathogen causing edwardsiellosis in aquaculture globally. Edwardsiella anguillarum has been recently described and is the more relevant pathogen in the eel farming industry. Here, we report the complete genome of the E. anguillarum strain C-5-1, isolated from a diseased giant mottled eel (Anguilla marmorata) cultured in Korea. The genome consists of a circular chromosome and one plasmid with 3,771 protein-coding genes, 25 rRNAs, 99 tRNAs, 6 ncRNAs, and 109 pseudogenes. Moreover, several genes for virulence and antimicrobial resistance, prophage regions, and CRISPR spacers were detected in the C-5-1 genome. Interestingly, tet(D) in this plasmid is almost identical (> 99%) to other closely related bacteria found in Korea and Japan, suggesting that it could be associated with increasing antimicrobial resistance of Edwardsiella spp.. This genomic information will provide important insights for strategies against prevalent pathogens in the Korean aquaculture industry.
