摘要
目的 探讨肠球菌溶血素的毒力因子作用。方法 分别检测 3 9株临床标本分离的粪肠球菌以及 3 1株健康人群粪便分离的粪肠球菌的溶血素检出率 ;并检测了β溶血肠球菌、非 β溶血肠球菌对 9种抗生素的敏感性。 结果 临床菌株的溶血素检出率为 5 8.9% ,健康人群分离株的溶血素检出率为 19.3 % (P <0 .0 0 5 ) ;β溶血株对抗生素的耐药性明显高于非 β溶血株 (P <0 .0 1)。
Aim To investigate the virulent effect of enterococci hemolysin.Methods Incidence of hemolysin of enterococus faecalis were examined in 39 clinical isolates and 31 healthy people fecal specimens respectively;antibiotic susceptibilities were compared between β-hemolytic strains and non β-hemolytic strains.Results 58.9% strains derived from clinical isolates were found to be β-hemolytic,and strains derived from healthy people fecal specimens exhibited a lower (19.3%) incidence of hemolysin(P<0 005).The β-hemolytic strains exhibited drug resistance more frequently than did the non β-hemolytic strains(P<0 01).Conclusion These results implied that hemolysin contributed to the virulence of enterococus faecalis .
