Bacteria Distribution of Clinical Specimen and Drug Resistance Analysis / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the clinicl bacteria distribution and the drug resistance.METHODS The biochemical and serologic tests were used to detect the susceptibility of bacterium to antimicrobials.RESULTS The positive rate was 44.87%,bacteria distributed mainly in sputum,urine and secretion.Pseudomonas aeruginosa,Escherichia coli,Staphylococcus epidermidis,Klebsiella pneumoniae and Acinetobacter often appeared.The drug resistance rate of MRSA and MRCNS was higher than MSSA and MSCNS's.The drug sensitive rate of Enterococcus faecium was less than E faecalis's.Bacteria of Enterobacteriaceae were sensitive to the drug of imipenem.The test rate for E.coli and K.pneumoniae which released ESBLs was 23.9% and 25.4%,respectively.P.aeruginosa possessed high resistance to all drugs.CONCLUSIONS The rate of Gram-positive cocci in all specimen is rising,the drug resistance is rather related with the broad use of antimicrobials.
