Abstract:
OBJECTIVE To investigate distribution and drug resistance status of Stenotrophomonas maltophilia.METHODS Microscan WalkAway-40 automatic analyzer from American Dade Company was used to identify bacteria.PCIZ and NC11 combination plate was used to perform susceptibility test in vitro.The data were analyzed by WHONET5.3 software.RESULTS The susceptibility to 15 antibiotics was tested in 42 clinic isolates of S.maltophilia from Jan 2005 to Sept 2006.The drug susceptibility test showed that SMZ-TMP had the lowest resistance rate(21.4%).Then resistance rate of S.maltophilia to cefoperazone-sulbactam was 23.8%.And 100.0% isolates were resistant to imipenem and aztreonam.CONCLUSIONS S.maltophilia has natural broad-spectrum resistance.We should strengthen its monitoring and control.
