【摘要】 目的 :比较临床分离肠球菌与肠道肠球菌的不同特性。方法 :分别检测 4 1株临床分离肠球菌以及 38株健康人群粪便分离肠球菌的属种分布、β溶血素检出率及耐药性情况。 结果 :临床菌株以粪肠球菌为主 (75 6 % ) ,健康人群粪便分离肠球菌以屎肠球菌为主 (73 7% ) ;临床菌株的 β溶血素检出率高于健康人群粪便分离肠球菌 (P <0 0 1) ;临床分离肠球菌的抗生素耐药性明显高于肠道肠球菌 (P <0 0 1)。结论 ;引起医院感染的肠球菌与肠道球菌特性不同。更多还原

【Abstract】 Objective:To investigate the different traits of Enterococci derived from intestines and clinical isolates.Methods:Species,incidence of β hemolysin and drug resistance were examined in 41 clinical isolates and 38 healthy people fecal specimens respectively.Results:75 6% clinical strains were Enterococcus faecalis ,and Enterococcus faecium are the major species in strains dervied from healthy people fecal specimens(73 7%);β hemolysin incidence of clinical strains are higher than that of intestinal strains( P <0 01);Clinical strains exhibited more drug resistance than that of intestinal strains ( P <0 01).Conclusion:traits of clinical Enterococci strains are different from those derived from intestines.更多还原
