Abstract

The in vitro activity of ceftizoxime was compared with that of other beta-lactam antibiotics against 538 isolates. Ceftizoxime was the most active agent tested against Escherichia coli and Klebsiella, inhibiting 80% at 0.025 microgram/ml. It was more active than cefotaxime against Enterobacter cloacae and E. aerogenes. Ceftizoxime was more active than cefoxitin, cefotaxime, cefoperazone, and carbenicillin against Proteus mirabilis and indole-positive Proteus. It inhibited 97% of multiresistant Serratia isolates at 12.5 microgram/ml, whereas cefotaxime inhibited only 19%. Ceftizoxime was less active than cefotaxime and cefoperazone against Pseudomonas aeruginosa, but was more active than carbenicillin. It was more active than cefotaxime and cefoxitin against Bacteroides. It was not appreciably destroyed by beta-lactamases of Staphylococcus aureus, Enterobacteriaceae, or Pseudomonas.

摘要

将头孢唑肟的体外活性与其他β-内酰胺类抗生素针对538株分离菌的活性进行了比较。头孢唑肟是针对大肠杆菌和克雷伯菌测试的最具活性的药物,在0.025微克/毫升时抑制率达80%。它对阴沟肠杆菌和气杆菌的活性比头孢噻肟更强。头孢唑肟对奇异变形杆菌和吲哚阳性变形杆菌的活性比头孢西丁、头孢噻肟、头孢哌酮和羧苄西林更强。它在12.5微克/毫升时能抑制97%的多重耐药沙雷菌分离株,而头孢噻肟仅能抑制19%。头孢唑肟对铜绿假单胞菌的活性比头孢噻肟和头孢哌酮弱,但比羧苄西林强。它对拟杆菌的活性比头孢噻肟和头孢西丁更强。它不会被金黄色葡萄球菌、肠杆菌科细菌或假单胞菌的β-内酰胺酶显著破坏。
