Abstract:
OBJECTIVE To investigate the distribution and the antimicrobial resistance of Alcaligenes xylosoxidans and to provide the guidance of rational use of antibiotics.METHODS A.xylosoxidans was isolated and identified through VITEK-AMS all-automatic microbiology analysis system and its G~-bacilli identification cards(GNI) and drug sensitivity cards(GNS-KI/121) were also analyzed.Drug-resistance was tested by Kirby-Bauer disk(sensitivity) method((Bio-Merieux) and Oxoid products).RESULTS The drug-resistance rates to the 1st to 4th((except) CAZ) generation cephalosporins were more than 77%.The drug-resistance rate to the aminoglycosides was more than 76%,and to(ampicillin,) amoxicillin/CA,ampicillin/sulbactam,cefoxitin and cefuroxime were all 100%;but to(aztreonam) was 92.86%;66.67% and 44.44% strains were resistant to ciprofloxacin and(levofloxacin).(CONCLUSIONS) The detection rates of the multidrug resistant A.xylosoxidans have the tendency to increase yearly.The antibiotics should be used reasonably according to the results of drug sensitivity test in clinic.
