Distribution and Antibiotic Resistance Analysis of 1275 Pathogens Isolated from Urinary Tract Infection

OBJECTIVE To investigate the distribution and antibiotic susceptibility of pathogens causing urinary infection,for the guide of rational use of antimicrobial agents in clinic. METHODS The bacteria isolated from the middle segment urine sample were identified by ATB system,and K-B method was used to study the antimicrobial resistance.The data were analyzed by WHONET 5.3. RESULTS Escherichia coli was one of the most common bacteria in the urinary tract infection(57.6%),and then were Enterococcus(14.4%).The results of antibiotic susceptibility test in vitro showed the susceptibility rate of Enterobacteriaceae and Acinetobacter baumannii to imipenem,was 100.0%,but the resistance rate of Pseudomonas aeruginosa was 13.6%.Gram-positive cocci were sensitive to glycopeptide antibiotics and linezolid. CONCLUSIONS Clinician should pay attention to the kinds of pathogenic bacteria causing urinary tract infection and their susceptibility to clinically common used antibiotics for reasonable use of drugs.
