From 1981 to 1983, tty-one stains of P. multccida were isolat&I from dw±s (12 strains), geese (4), chickens (3), rabbit (1), and pig (1). The Minimal Growth Inhibitory Concentration (M IQ of 22 kinds of antibacterial agents against these 21 isolates were test!,
The result revealsi that these isolates were most sensitive to Ampicillin (M IC uimary O.39mcghnl), Penicillin (O.78mcghnl), and Flumequine (1 .S6mcghnl), followed by Gentamicin (3 .l3mcg/ml), Chlcrramphenicol (3.l3mcg/rnl), Erythxomycin (6.25mcg/ml), etc. Evaluat! by MICSQ Ampicil]in, Pencil]in, Flumepine, Chloramphenicol, Steptomycin were all lower than O.39mcg/m], follower! by Erythromycin (O.S8mcgknl), Genmycin (O.88mcghnl), etc.
