Abstract:
OBJECTIVE To understand pathogen distribution and drug sensitive rate of urinary system infection in our hospital,in order to avoid the clinic to use antibiotics blindly,make the resistant strains decreasing in number,and improve efficacy.METHODS The distribution and drug sensitivity of the pathogens causing urinary infection among the patients with urinary system infection were rectrospectively analyzed.RESULTS Totally 549 strains were isolated,G-bacteria were 333 strains,accounted for 60.66%,from them E.coli was 293 strains,accounted for 87.99%;and G+bacteria were 216 strains,accounted for 39.34%,from them Enterococcus,and Staphylococcus were the main ones.Of E.coli strains,the ESBLs(+) were 36.86%.The MRCNS accounted for 81.91%.The result of drug sensitivity showed that the sensitive rate of E.coli to meropenem and imipenem was 100.0%.The sensitive rate of ESBLs(+) E.coli to cefepime,cefotaxime and aztreonam was all lower than 50%,but that of ESBLs(-) to the above drugs was much higher than ESBLs(+).The sensitive rate of Enterococcus to vancomycin and teicoplanin was 100%.The sensitive rate of CNS to Vancomycin was 100%.CONCLUSIONS In order to decrease the produceing bacteria resistance and the disseminating the resistance genes,it′s necessary to enhance the monitoring and study of bacteria resistance,normlalize the clinical medicine application,and enhance the infection control measures.
