The in vitro susceptibility of 406 clinical isolates to BMY-28142, a new semisynthetic cephem, was evaluated and compared with cefpimizole, HR 810, ceftazidime, cefotaxime, moxalactam, and cefoperazone in a broth microdilution assay. On a weight basis, the activity of BMY-28142 against Escherichia coli, Proteus species, and Klebsiella-Enterobacter-Serratia was superior to the other cephems. Against gentamicin-susceptible and -resistant Pseudomonas aeruginosa, BMY-28142 was more active than the other cephems, except ceftazidime and HR 810. A total of 74% of gram-negative and 56% of gram-positive isolates resistant to third-generation cephalosporins were susceptible to less than or equal to 8 micrograms of BMY-28142 per ml. Finally, for 83% of tested isolates, the bactericidal concentration of BMY-28142 was within one dilution of the inhibitory concentration.
采用肉汤微量稀释法,对406株临床分离菌株对新型半合成头孢菌素BMY-28142的体外敏感性进行了评估,并与头孢咪唑、HR 810、头孢他啶、头孢噻肟、拉氧头孢和头孢哌酮进行了比较。以重量计,BMY-28142对大肠杆菌、变形杆菌属以及克雷伯菌-肠杆菌-沙雷菌属的活性优于其他头孢菌素。对于对庆大霉素敏感和耐药的铜绿假单胞菌,BMY-28142比其他头孢菌素更具活性,但头孢他啶和HR 810除外。总共74%的对第三代头孢菌素耐药的革兰阴性菌和56%的革兰阳性菌分离株对每毫升小于或等于8微克的BMY-28142敏感。最后,对于83%的测试分离株,BMY-28142的杀菌浓度在抑菌浓度的一个稀释度范围内。
