Ceftazidime is one of the few cephalosporins with activity against Pseudomonas aeruginosa Using whole-genome comparative analysis, we set out to determine the prevalent mechanism(s) of resistance to ceftazidime (CAZ) using a set of 181 clinical isolates. These isolates represented various multilocus sequence types that consisted of both ceftazidime-susceptible and -resistant populations. A presumptive resistance mechanism against ceftazidime was identified in 88% of the nonsusceptible isolates using this approach.
头孢他啶是少数对铜绿假单胞菌有活性的头孢菌素之一。我们利用全基因组比较分析,通过一组181株临床分离株来确定对头孢他啶(CAZ)耐药的普遍机制。这些分离株代表了多种多位点序列类型,包括头孢他啶敏感和耐药群体。使用这种方法,在88%的非敏感分离株中确定了一种推测的头孢他啶耐药机制。
