Abstract:
Objective To provide evidences for rational use of antibiotics in treatment of hospital-acquired urinary tract infection.Methods The bacteria isolated from mid-stream urine samples were collected for susceptibility test(MIC)using international standard plate dilution method.According to breakpoints defined in CILS guidelines(2009),each strain of bacteria was determine for susceptibility to antimicrobial agents,and calculated for rates of resistance(R%),intermediate(I%)and susceptibility(R%)to compounds tested.Results 552 strains of bacteria were collected,including 432 strains(78.3%)of Gram-negative bacilli and 120(21.7%)of Gram-positive bacilli;Escherichia coli was one of the most common bacteria in the urinary tract infection(55.3 %),followed by Enterococcus(17.4%).The results of antibiotic susceptibility test in vitro showed that Enterobacteriaceae was 100% susceptible to imipenem;Gram-positive cocci were sensitive most to glycopeptide antibiotics.Conclusion Clinicians should pay attention to the species of pathogenic bacteria causing urinary tract infection and their susceptibility to clinically common used antibiotics for reasonable use of drugs.
