A total of 28 strains of avian vibrio showed a high sensitivity to the antibacterial quinoxaline derivative, carbacox (CD), and the antibacterial nitrofuran derivative, panazon (PZ), at a minimum inhibitory concentration (MIC) of less than 0.78 and 3.13 mcg/ml (unit omitted hereafter), respectively. Moreover, 57.1% of them exhibited an MIC less than 0.09.
Six strains ofVibrio fetus, 1 Strain of V.bubulus, and 3 strains ofV. coliwere also sensitive to the two drugs, showing almost the same MIC as the avian vibrio.
Twelve strains ofV. parahaemolyticusmanifested a very low sensitivity or a resistance to both drugs. Most of them showed an MIC of 100 for CD and more than 200 for PZ. There was no difference in drugsensitivity between strains of different origin or different biochemical properties.
