Abstract:
OBJECTIVE To investigate the resistance of Pseudomonas aeruginosa strains to 5 ?-lactams.METHODS Susceptibility of 218 P.aeruginosa strains isolated from Anhui Province in 2005 to ceftriaxone,cefotaxime,ceftazidime,aztreonam,and piperacillin were tested by agar dilution method.RESULTS The resistance rate to ceftriaxone,cefotaxime,aztreonam,piperacillin,and ceftazidime were 59.2%,57.3%, 56.0%,51.8%,and 39.0%,respectively.There was statistically significant difference between ceftazidime and other 4 ?-lactams(P0.05).CONCLUSIONS Ceftazidime is the most susceptible antibiotic to P.aeruginosa strains among 5 ?-lactams tested.
