Two hundred and fifty strains of Aeromons liquefaciens isolated from fishes and soft-shelled turtles were studied for their sensitivity to 9 sorts of chemotherpeutics using agarplate dilution method. One hundred and ten of the 250 strains were additionally tested for sensitivity to 3 other drugs. Most of the strains tested were highly sensitive to chloramphenicol, chlortetracycline, tetracycline, relatively high sensitive to nifuriprinol, sulfamonomethoxine, and sulfisoxazole and moderately sensitive to fradiomycin, furazolidone, nitrofurazone, streptomycin and kanamycin and resistant to aminobenzyl penicillin. Criteria for defining resistant strains to the drugs were tentatively determined. According to the criteria out of the 250 strains 28 were one-drug-resistant, 38 were two-drug-resistant, 4 were three-drug-resistant and 8 were four-drug-resistant. Tetracycline-sulfanilamide resistance was a characteristic resistance pattern of drug-resistant A. liquefaciens.
