摘要

目的：了解抗菌药物对某院临床分离肠球菌属细菌的体外抗菌活性。方法对2013年6月—2014年7月该院临床各科室送检标本分离的188株肠球菌属细菌进行细菌鉴定及药物敏感试验。结果188株肠球菌属细菌其中屎肠球菌119株、粪肠球菌60株、鸟肠球菌9株，主要分布在尿和血标本，分别占34．57％和19．15％。未检出对达托霉素及利奈唑胺耐药的肠球菌属细菌；屎肠球菌对万古霉素的耐药率为1．68％，对青霉素、氨苄西林、高浓度庆大霉素、红霉素、左氧氟沙星的耐药率均＞70％；除四环素外，粪肠球对其他抗菌药物的耐药率均低于屎肠球菌，粪肠球对青霉素、氨苄西林耐药率较低，分别为16．67％，13．33％。结论达托霉素对该院肠球菌属细菌具有良好的抗菌效果。%Objective To investigate in vitro activity of antimicrobial agents against Enterococcus spp . isolated from clinic specimens in a hospital.Methods 188 Enterococcus spp . isolates from specimens sent by clinic depart-ments in June 2013-July 2014 were identified and performed antimicrobial susceptibility testing.Results Of 188 En-terococcus spp . isolates,119 were Enterococcus faecium (E.faecium),60 were E.faecalis ,and 9 were E.avium, these strains were mainly isolated from urine (34.57%)and blood specimens (19.15% ).No daptomycin and linezolid-resistant strain was detected;resistant rates of E.faecium to vancomycin was 1 .68%,to penicillin, ampicillin,high concentration gentamycin,erythromycin,and levofloxacin were all > 70%;except tetracycline, resistant rates of E.faecalis to the other antimicrobial agents were all lower than E.faecium,resistant rates of E. faecalis to penicillin and ampicillin were 16.67% and 13.33% respectively.Conclusion Daptomycin has high activity against Enterococcus spp . in this hospital.
