The surveillance for the antimicrobial resistance of salmonella pullourm from 1962 to 1999

摘要

346 Salmonella Pullorum strains were collected and preserved from some regions in Chian from 1962, to 1999. All strains were studied for antimicrobial susceptibility testing by menas of Kirby-bauer method. The results in the study showed that almost all 346 isolates had the capacity of acquiring antimicrobial resistance. Only a few showed single resistance pattern, while most strains revealed multiresistance patterns. The antimicrobial resistance spectrums of 346 isolates were grouped into 57 different types, and most strains showed resistance to antimicrobial agents commonly prescribed in veterinary clinics.
