Abstract. Isolates of Aeromonas salmonicida were obtained from farmed Atlantic salmon, salmo salar L., with amoxicillin minimum inhibitory concentrations (MICs) of 2·5–10 μg ml ‐1 Several antibiotic sensitivity patterns were found among the isolates including resistance to the four UK‐licensed antibacterial drugs. Combination of clavulanic acid with amoxicillin was not effective, but all isolates were sensitive to florfenicol and to a cephalosporin, the latter having very low MICs.
