Distribution and Resistance of Pseudomonas aeruginosa:Analysis of 244 Strains / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the distribution and resistance of Pseudomonas aeruginosa isolated during Jan-Dec 2006.METHODS The clinically isolated P.aeruginosa strains were collected cultured and identified by paper diffusing method or trace dilution method(MIC),the results were evaluated according to the relevant documents of NCCLS of USA.RESULTS The in vitro susceptibility test of 244 P.aeruginosa isolates to 16 kinds of antibacterials indicated the resistance rate to SMZ was the highest(98.8%);then to minocycline,tetracycline and ticarcillin/clavulanicacid(70.1%,58.6% and 54.5% respectively).CONCLUSIONS To strengthen the continuous survezillance of drug resistance of P.aeruginosa,to sum up the resistance rules of main pathogens of departments in hospital and to reduce of production of resistant bacterica have the important significance.
