Pathogen Investigation and Drug Susceptibility Spectrum Analysis in Nosocomial Urinary Tract Infections in Hengyang Area During 2010～2011

Objective To investigate the bacterial distribution and antibiotic resistance situation of main pathogens with urinary tract infection(UTI) in Henayang area for the guidance of rational use of antibiotics.Methods The antibiotic resistance of clinical isolates patgogens were studied from urinary tract infection by routine bacterium culture in our hospital from Jan 2010 to Dec 2011.Result There were 1 505 strains of pathogens in the whole 5 013 unary samples,and the isolating rate was 30.0%.The most common pathogen in urinary tract infection was Escherichia coli(52.1%),then the Enterococcus(11.5%),and the fungi was 10.3%.Gram-negative bacilli was found to be sensitive to imipenem and Meropenem,while staphylococci and Enterococcus were sensitive to furadantin and vancomycin,and the other strains were highly resistant to some antibiotics.Conclusion The resistantce of pathogenic bacteria is serious among the urinary tract infection.We should carry through cultivation,isolation,and antimicrobial susceptibility testing as soon as possible in clinical jobs to guide reasonable clinical drug therapy.
