Distribution and Drug Resistance of Pathogens in Urinary System Infection

OBJECTIVE To study the distribution and drug resistance characteristic of pathogens in urinary system infection,and to provide basis for clinicians to select antibiotics correctly and to control nosocomial urinary infection. METHODS A total of 129 pathogen strains were identified, which were isolated from urine of our hospital patients with urinary system infection. ESBLs producing G - bacteria, and oxacillin resistance in staphylococci were detected and high level aminoglycoside resistance in enterococcus(HLAR) were screened. RESULTS Among 129 strains, 51 16% were Escherichia coli, 10 85% Staphylococcus aureus, 7 75% coagulase negative Staphylococcus(CONS), 6 20% Enterococcus and 5 43% Pseudomonas were detected respectively. 25 76% E.coli and 40 00% Klebsiella pneumoniae produced ESBLs; 57 14% S.aureus and 50 00% CONS were resisted to oxacillin; HLAR producing Enterococcus was 50 00%. CONCLUSIONS Much attention should be paid to do detection and drug resistance of pathogens in urinary system infection. It is important to control nosocomial urinary infection and select antibiotics correctly.
