Detection of Proteus and Analysis of Drug-resistance in Intensive Care Unit / 医学研究杂志

ABSTRACT

Objective To detect the proteus and analyze the drug-resistance in intensive care unit.Methods From Jan 2005 to Dec 2006,proteus was detected by Disc diffusion test(K-B method)to study the antimicrobial resistance in ICU and general ward,and compared the drug-resistance.Results The isolating rate of proteus was 80.9% in sputum,and proteus mirabilis accouted for 80.4%.The resistance rates to ciprofloxacin,amikacin,cefotaxim,ceftazidime,cefmetazole and piperacillin/Tazobactam were between 64%~77%,and 32%~41% in imipenem and cefoperazone/sulbactam.Compared with general ward,the antibiotic resistant rate existed significant difference.And the antibiotic resistant rate of other type proteus had significant difference between ICU and general ward.Conclusion Properly detecting Proteus in time is imporrant to use antibiotic and to avoid nosocomial outbreak infections by Proteus.
