Comparison of drug resistance between mucoid and non-mucoid Pseudomonas aeruginosa / 中华临床感染病杂志

ABSTRACT

Objective To compare the drug resistance of mucoid Pseudomonas aeFagillosa with that of non-mucoid.Methods All specimens isolated and cultured from patients were identified and the antibiotic sensitivity was tested by automatic microorganism analyzer VITEK-32,GNI+,GNS-448,E-teat and K-B.Results Drug resistant rates of mucoid Pseudomonas aeruginosa to imipenem.levofloxacin.meropenem,cefepime,cefoperazone/sulbactam,amikacin,gentamicin,piperacillin.tazobactam,ceftazidime and cefotaxime were 5.3%, 16.1%, 5.6%, 20.6%, 1.1%, 10.5%,26.9%,5.3%.31.5% and 60.2%,respectively.The drug resistant rates of mucoid Pseudomonas aeruginosa were lower than those of non-mucoid except to ceftazidime.Conclusion Compared with non-mucoid Pseudomonas aeruginosa,antibiotic resistance of mucoid Pseudomonas aeruginosa is weaker in vitro.
