仔猪黄痢的病原分离鉴定及药敏试验

The Piglet Diarrhea Escherichia Coli Separated,Identified and Drug Sensitive Test

对贵州省某养猪场发生仔猪黄痢的病例进行病原分离鉴定,病仔猪直肠拭子接种至普通营养琼脂平板、麦康凯琼脂平板,经革兰氏染色镜检和生化试验,鉴定为大肠埃希氏菌;药敏试验表明,该菌对头孢哌酮、头孢曲松高度敏感,对环丙沙星、庆大霉素和卡那霉素等药物不敏感。根据药敏试验指导用药后,仔猪恢复健康。

In order to determine the main pathogenic bacteria types which lead the death of 4 group of pigs in Guizhou province, the rectal swab of pig was resorted sterilely, bacteria from which then was isolated and purified. Dased on dyeing and biochemical tests determined that escherichia eoli was the main pathogenic bacteria. Drug sensitive test showed that the pathogen was very sensitive to cefoperazone and ceflriaxone, but was not to ciprofloxacin, gentamicin and kanamycin. We can screen some sensitive drugs to provide theoretical basis and practical parameters of treatment and prevention.
