|
A total of 315 microorgainisms were isolated from 256 pneumonic lung samples of pig in abattoirs of northern Chungnam area during February to November 1994, and Identified 97 strains as Pusteurella multocida, 89 strains as Staphylococcus spp, 54 strains as Streptococcus spp, 22 strains as Mycoplasma spp, 21 strains as Escherichia coli, 18 strains as Haemophilus parsuis, 11 strains as Corymebacteroi, pyogenes, and 3 strains as Acrinobacillus spp by Gram’s and Dienes stain, and biological properties test Involved API system. After that, they were examined anti biotic susceptibility for ampicillin(AM), cephalothin(CF), chloramphenicol(CP), erythromycin(EM), kanamycin(KM), gentamicin(GM), neomycin(NM), penicillin(PC), streptomycin(SM), tetracycline(TE), tiamulin(TIA), tylosin(TYL), methicillin(DP), colistin(CL) and trimet hoprim(SXT). In antibiotics susceptibility test, 293 isolates except Mycoplasma spp 22 strain were highly susceptible to DF(79.2%) and AM(76.2%), but resistant to PC(14.0%), NM(19.5%) and KM (23.2%) The multiple drug resistant patterns were noted in most isolates, whereas only 7 isolates resistant to single drugs.
