of bacteria with 0.5 McFarland turbidity was prepared in sterile PBS and cultured on Mueller–Hinton agar for 24 h at 28 ± 2°C. After the incubation, the inhibition zones were measured. Nine compounds were used representing the antimicrobials frequently used in aquaculture belonging to the folate-path inhibitor, quinolone, tetracycline, and phenicol classes ( Table 4 ). Since there are no interpretation criteria for Shewanella , for better understanding of the susceptibility results some criteria for Aeromonas salmonicida were used ( 6 ). Enzymatic properties
