Abstract:
Objective To explore the differences in antimicrobial resistance of bacteria isolated from different samples ,and to guide antibiotic chemotherapy in clinic .Methods The sputum ,blood ,pus and urine specimens were collected from 2009 to 2013 in our hospital for bacterial identification and drug sensitivity tests by using automatic system .The drug resistance rate of Staphylo‐coccus aureus ,Escherichia coli ,Klebsiella pneumoniae isolated from different samples were compared .Results All isolates of E .co‐li ,Klebsiella pneumoniae were sensitive to imipenem ,ertapenem ,piperacillin/tazobactam and amikacin .All isolates of S .aureus were sensitive to vancomycin ,linezolid ,nitrofurantoin ,quinupristin/dalfopristin .The ESBLs positive rate of E .coli(71 .5% )and the MR‐SA detection rate(79 .9% ) of Staphylococcus aureus from sputum samples were significantly higher than that from other samples (P<0 .05) .The ESBLs positive rate(44 .4% ) of Klebsiella pneumoniae isolates from urine was significantly higher than that from other samples(P<0 .05) .Conclusion The same bacteria isolated from different samples have different antimicrobial resistance rates ,so the selection of antibiotics should based on drug sensitivity tests results for the treatment of the same pathogen infection confirmed by bacterial cultures from different samples .
