These strains were tentatively identified as A. popoffii on the base of the negative sucrose acidification, which is a typical trait of this species. MALDI-TOF MS showed the highest discriminatory power for presumptive A. popoffii isolates and this method seems to be valuable for species identification of A. hydrophila group. RiboPrinter demonstrated great heterogeneity of ribotyping patterns among A. popoffii strains but their identification is impracticable due to the absence of A. popoffii reference patterns in the RiboPrinter identification database. Four presumptive A. popoffii isolates (P3282, P4293, P4571 and P4573) displayed very distinct riboprint profiles. Their further investigation using 16S rRNA and cpn60 genes sequencing assigned these strains as Aeromonas veronii and Aeromonas sobria species. ER -
