Abstract:
OBJECTIVE To study the distribution and drug resistance conditions of inpatients in our hospital and make us antibiotics use reasonable.METHODS Retrospective analysis was conducted from all the pathogens of the clinical specimens from 2007-2008 and the data were analysed.RESULTS A total of 5508 pathogens were isolated from 2007-2008.Among 2441 pathogens(44.32%),there were Gram-negative bacilli(Enterobacteriaceae 1715 pathogens,Nonfermenters 707 pathogens,Vibrionaceae 19 pathogens),1154 pathogens(20.95%) were Gram-positive bacilli,1906 pathogens(34.60%) were Fungi.There were 331 pathogens which extended spectrum ?-lactamases(ESBLs) of Enterobacteriaceae(19.30%).The resistance of Escherichia coli to amikacin,ceftazidime,gentamicin,ciprofloxacin,piperacillin resistance rates were 10.94%,60.53%,62.08%,82.01%,86.46%,resistance of Enterobacter cloacae to amikacin,ciprofloxacin,gentamicin,piperacillin,ceftazidime resistance rates were 30.61%,46.29%,52.96%,55.20%,53.05%,resistance of Klebsiella pneumoniae to ciprofloxacin,amikacin,gentamicin,ceftazidime,piperacillin resistance rates were 13.04%,15.90%,16.90%,20.17%,30.07%,The resistance of E.coli,E.coli to ceftazidime,gentamicin,ciprofloxacin,piperacillin were not found were than 60.00%,E.cloacae to gentamicin,piperacillin,ceftazidime not more than 50.00%,K.pneumoniae to ciprofloxacin,amikacin,gentamicin,ceftazidime resistance rates more than 30.00%,not found E.coli,E.cloacae,K.pneumoniae PEI-pei South-resistant strains.The resistance of Pseudomonas aeruginosa to imipenem,amikacin,ciprofloxacin were less than 20.00%,the resistance rate of Acinetobacter baumannii more than 40.00%;of 199 methicillin resistant staphylococcus were not found out vancomycin-resistant S.aureus strains.CONCLUSIONS More of the pathogens show multiple drug resistance.It is urgent for surveillance of bacterial resistance and rational use of anti-microbial agents during the clinical therapy.
