中文摘要:

      目的 了解深圳市畜禽产品检出的沙门氏菌的血清型与耐药性。方法 选取2013~2015年分离出的70株沙门氏菌, 进行血清型鉴定和药物敏感性试验。结果 共确定了18个血清型, 以伦敦沙门氏菌检出数量最多。药敏试验结果显示, 70株沙门氏菌有24种多重耐药谱, 全部菌株对头孢唑啉、阿米卡星和庆大霉素耐药, 对厄他培南、亚胺培南和美洛培南敏感。耐药5种及5种以上菌株在猪肉中占78.0%, 数量最多。结论 建立食源性沙门氏菌耐药性的长期监测机制, 对该病原菌的防控及指导养殖业和临床合理用药具有现实和医学意义。

英文摘要:

      Objective To investigate serotype and drug resistance of Salmonella from livestock and poultry products in Shenzhen. Methods A total of 70 strains of Salmonella were isolated during 2013~2015 which were selected to do the test of serotype identification and drug sensitivity test. Results Totally 18 serotypes were identified, with the largest number of S.london. Drug sensitivity test showed that there were 24 kinds of multiple drug resistant spectrums from 70 strains of Salmonella. All of the strains were tolerant to Cephazolin, Amikacin and Gentamycin, and were sensitive to Ertapenem, Imipenem and Meropenem. The strains which were resistant to 5 or more than 5 antibiotics in pork were the most, accounting for 78.0%. Conclusion It has an important practical and medical significance for prevention, guidance and rational drug use of salmonellosis to build up a sustained monitoring system for the resistance of Salmonella.
