Abstract excerpt

This study explores the phenotypic, genotypic, and serological differences among Edwardsiella ictaluri isolated from farm-raised catfish Ictalurus spp. and ornamental fish (Danio spp. and Puntius tetrazona) in the USA. Plasmid analyses revealed diverse plasmid profiles, with varied antimicrobial resistance genes indicating diverse resistance and virulence mechanisms. Analysis of complete genome sequences revealed...
