摘要: 旨在掌握河南省猪源粪肠球菌的耐药情况。从规模化猪场抽取样品300批,采用常规方法进行粪肠球菌分离、培养、纯化,应用全自动细菌鉴定/药敏系统和PCR技术对分离菌株进行种水平鉴定,利用微量肉汤稀释法对分离菌株进行药物敏感性分析。结果表明,有154株分离菌被鉴定为粪肠球菌,总体分离率为51.33%;分离菌株对头孢西丁、克林霉素、泰妙菌素、头孢噻呋、磺胺异噁唑、红霉素、替米考星等抗菌药物耐药严重,耐药率均在90%以上,对强力霉素(多西环素)、氟苯尼考、青霉素、复方新诺明耐药性相对较强,耐药率在60%-90%。综上提示,河南省猪源粪肠球菌耐药情况严重。

Abstract: The aim of the present study was to characterize the antimicrobial resistance of Enterococcus faecalis(E. faecalis)isolates from swine in Henan Province. A total of 300 batches of samples were collected from scaled pig farms; the isolation,culture, and purification of E. faecalis strains were performed by using conventional methods; the isolates were subsequently identified to species level by using automatic bacterial identification/antimicrobial susceptibility test system and PCR assay;micro-broth dilution method was used to evaluate the susceptibility of the isolates to antimicrobial agents. The results showed that a total of 154 strains were identified as E. faecalis and the overall isolation rate was 51.33%; high resistance rates were detected for cefoxitin, clindamycin, tiamulin, ceftiofur, sulfisoxazole, erythromycin and tilmicosin(all above 90%); isolates also exhibited resistance to doxycycline, florfenicol, penicillin and compound sulfamethoxazole, with resistance rates ranging from 60% to 90%.It is indicated that the antimicrobial resistance status of E. faecalis isolates from swine in Henan Province is serious.
