Abstract: The phenotypic properties and genotypic characteristics of 44 aeromonads isolated from fish affected by epizootic ulcerative syndrome (EUS) in Southeast Asia were investigated. Among the 13A. hydrophila phenospecies 9 were genotypically identical to A. hydrophila (HG1) and 4 were A. veronii biotype sobria (HG8Y) or A. veronii biotype sobria-related genospecies. All the 6 A. veronii biotype sobria phenospecies were placed in the same genospecies, A. veronii biotype sobria. Of the 12 A. jandaei phenospecies, 5 were A. veronii biotype sobria or A. veronii biotype sobria-related genospecies and 7 were A. jandaei genospecies. Of 13 Aeromonas isolates unspeciated by phenotyping 9 were genotypically identical to A. hydrophila or very similar to A. hydrophila and 2 isolates were A. veronii biotype sobria or very similar to A. veronii biotype sobria; 2 isolates could not be identified to genospecies level. These results strongly suggest that Aeromonas species from fish affected by EUS could not correctly be identified to the species level using various published biochemical schemes; it needs genetic identification like DNA-DNA hybridization.
