A total of 521 unique clinical isolates from cancer patients with primarily (>90%) bloodstream infections were tested for susceptibility to ceftazidime-avibactam and comparators using broth microdilution methods. Ceftazidime-avibactam inhibited 97.8% of all ( = 321) at the susceptibility breakpoint of ≤8/4 μg/ml (there were 7 nonsusceptible strains). It was also active against (91.7% isolates susceptible, = 121), including many isolates not susceptible to meropenem, cefepime, ceftazidime, piperacillin-tazobactam, or other comparators.
使用肉汤微量稀释法,对总共521株主要来自癌症患者(>90%)血流感染的独特临床分离株进行了头孢他啶-阿维巴坦及对照药物的敏感性测试。在≤8/4 μg/ml的敏感折点下,头孢他啶-阿维巴坦抑制了所有321株菌株中的97.8%(有7株不敏感菌株)。它对121株耐碳青霉烯类肠杆菌科细菌(CRE)也有活性(91.7%的分离株敏感),包括许多对美罗培南、头孢吡肟、头孢他啶、哌拉西林-他唑巴坦或其他对照药物不敏感的分离株。
