Abstract: 【Abstract】 Objective〓To investigate the bacterial distribution and drug resistance of urinary tract infection in adolescent patients. Methods〓From July 2014 to July 2015, 44 patients (aged between 18 and 20) with urinary tract infections were assigned as research subjects. Urine specimen were collected in the middle of urination for urine culture. A total of 1382 isolated bacterial colonies were found. The kinds of pathogens responsible for urinary tract infection,bacterial distribution,antimicrobial susceptibility and resistant strains were analyzed. Results〓The causative organisms included gram-positive bacteria 20.12%, 3.04% fungi, Gram-negative bacteria 76.85%. Most of the bacteria were E.faecium and E.faecalis in the detected gram-positive bacteria (76.91%), E.coli and Pseudomonas aeruginosa in the detected gram-negative bacteria(73.54%),Candida parapsilosis and Candida albicans in the detected fungi. Staphylococcus aureus was the highest resistant to Ciprofloxacin, and E.faecium was to ofloxacin, E.faecalis was to clindamycin,E.coli was to ceftriaxone,pseudomonas aeruginosa was to aztreonam,klebsiella pneumoniae was to Ceftriaxone,citrobacter was to Ciprofloxacin. Conclusion〓As for the young bacterial urinary tract infection patients,Gram-negative bacteria was the main drug-resistant pathogens, especially Escherichia coli.
