Abstract
To study the antimicrobial resistance of clinically isolated Salmonella pullorum strains,identification,morphology observation and biochemical test were used to identify the isolates from 33 suspected pullorum specimens of chicks and there were 26 Salmonella pullorum isolates. The isolates against sensitivity of 14 antimicrobial drugs were evaluated by K-B disc diffusion method. The results showed that Salmonella pullorum isolates were more sensitive to gentamiein, amikaein,neomycin,polymyxin B, cotrimoxazole and chloramphenicol. Resistance rate was 11.54% ,0,7.69% ,0,19.23% and 15.38% respectively. The resistance of SalmoneUa puUorum isolates to amoxicillin,ampicillin,streptomycin,tetracycline,doxyeycline,enrofloxacin,norfloxacin and ciprofloxacin were strong. Resistance rate was 53.85%, 65.38%,57.69%, 100%, 69.23%, 61.54%, 76.92% and 53.85% respectively. The pattern of drug resistance showed that all Salmonella pullorum isolates were resistant to three or more antimierobials,including resistance to 6 and 7 resistant strains dominated,accounting for 42.31% and 30.77%. Salmonella pullorum isolates had different degrees of antimicrobial resistance for most antimicrobial agents. To strengthen the monitoring of antimicrobial resistance of clinical isolates had practical significance for guiding the clinical therapy and controlling of pullornm epidemic.关键词
