The in vitro activity of cefonicid against 60 strains of viridans group streptococci isolated from blood of patients with bacteremia and infective endocarditis was compared with those of cefazolin and penicillin. Cefonicid was less active than cefazolin, and both cephalosporins were less active than penicillin. The MIC50 and MIC90 for the strains tested were 0.06 and 1 microgram/ml for penicillin, 0.125 and 8 micrograms/ml for cefazolin, and 4 and 32 micrograms/ml for cefonicid.
将头孢尼西对从菌血症和感染性心内膜炎患者血液中分离出的60株草绿色链球菌的体外活性,与头孢唑林和青霉素的体外活性进行了比较。头孢尼西的活性低于头孢唑林,且两种头孢菌素的活性均低于青霉素。所测试菌株的青霉素MIC50和MIC90分别为0.06和1微克/毫升,头孢唑林为0.125和8微克/毫升,头孢尼西为4和32微克/毫升。
