摘  要:
为了解死亡鸡胚中沙门菌的感染状况,从河南省4家三黄种鸡场自带孵化场采集死胚样品,进行沙门菌分离、血清型鉴定,并用纸片法和PCR方法对菌株耐药表型及相关耐药基因进行检测。结果:从356份死胚样品共分离到173株沙门菌,包括5种血清型:鸡白痢沙门菌(162株)、布利丹沙门菌(5株)、塞罗沙门菌(4株)、肠炎沙门菌(1株)、菲尔摩雷沙门菌(1株)。不同来源死胚中沙门菌的分离率和耐药情况差异显著;173株沙门菌对磺胺异噁唑(82.1%)、氨苄西林(74.0%)、四环素(49.1%)、土霉素(48.6%)耐药情况较严重,且43.4%(75/173)的菌株表现为多重耐药;对其他抗生素耐药情况较轻,耐药率在11%以下;对头孢他啶、美罗培南、亚胺培南、多黏菌素E、氯霉素、恩诺沙星、环丙沙星敏感。PCR共扩增到13种耐药基因,且耐药基因的检出情况与耐药表型的符合率在72%以上,其中ESBLs类、氨基糖苷类、头孢菌素类的符合率为100%。结论:三黄鸡鸡胚感染的沙门菌血清型复杂、多重耐药严重,且耐药基因普遍存在于耐药菌株中。

摘  要:
To investigate current infection statuses of Salmonellain dead chicken embryos,Salmonellastrains was isolated and identified from dead embryo samples collected from 4 hatcheries attached to their parental flocks of Sanhuang Chickens,and the drug resistance and resistance genes were detected by Kirby-Bauer Test and PCR method,respectively.A total of 173 Salmonellaisolates were obtained from 356 dead embryos,including 5 serotypes:S.pullorum(162),S.blegdam(5),S.Cerro(4),S.enteritidis(1),S.Fillmore(1).Results showed that the isolation rate and drug resistance of Salmonellain dead embryos from different sources were significantly different.Of total 173 Salmonellaisolates,the drug resistance rate to Sulfisoxazole(SF),Ampicillin(AMP),Tetracycline(TE)and Oxytetracycline(OT)were 82.1%,74.0%,49.1% and 48.6%.And 43.4%(75/173)isolates showed multiple drug resistance.The resistance to other drugs was mild,and the resistance rate was below 11%.The isolates were sensitive to Ceftazi-dime(CAZ),Meropenem(MEM),Imipenem(IPM),Polymyxin E(CT),Chloramphenicol(C),Enrofloxacin(ENR)and Ciprofloxacin(CIP).In addition,13 drug-resistant genes were detected by PCR,and the coincidence rate between drug-resistant phenotype and drug-resistant genes was more than 72%,especially the rate were 100% to extended-spectrum beta-lactamases(ESBLs),aminoglycosides,cephalosporins.The results indicate that serotypes of Salmonella infected in Sanhuang chicken embryos are complex,the multi-drug resistance is serious and the resistance genes are widely existed in these resistant strains.
