Isolation, Identification, and Characteristics of <i>Aeromonas salmonicida</i> subsp. <i>masoucida</i> from Diseased Starry Flounder (<i>Platichthys stellatus</i>).

ABSTRACT: Aeromonas salmonicida is a predominant pathogen that infects fish. The pathogen A. salmonicida subsp. masoucida (ASM) was isolated for the first time from diseased starry flounders (Platichthys stellatus). Our study aimed to isolate, characterize, and investigate the pathogenicity of ASM. Bacterial species were identified using 16s rRNA, gyrB, dnaJ, and vapA analyses. Phylogenetic tree analysis revealed that the ASM strains were clustered with the ASM ATCC strain and other strains isolated from black rockfish. In the antimicrobial susceptibility test, the three ASM strains were considered non-wild types for enrofloxacin, florfenicol, flumequine, oxolinic acid, and oxytetracycline susceptibility. Histopathological analysis revealed bac
