The Minimum Inhibitory Concentration (MIC) for both antimicrobials was ≤ 8 μg/ml suggesting that all of the tested isolates were susceptible to both antimicrobials. The observed MIC range of FF (0.5-4.0 μg/ml) was more potent than that of CAP (0.5-8.0 μg/ml). The activity of both antimicrobials was not substantially influenced by the addition of sea water (5 ppt salinity) to the test system. When considering the best type of antimicrobial for food producing animals and in vitro antivibrio activity, FF …
