Distribution and drug resistance of pathogens isolated from urine culture in 2013 from a 3A hospital / 国际检验医学杂志

ABSTRACT

Objective To investigate the distribution and drug resistance of pathogens isolated from urine culture in 2013 and provide basis for clinical treatment .Methods MicroScan WalkAway 96 PLUS bacterial identification system was used to identify the pathogens and drug susceptibility testing .The data were analyzed by WHONET 5 .6 software .Results A total of 231 strains of pathogens were isolated from urine cultures ,including 51(22 .1% ) strains of gram‐positive bacteria ,170(73 .6% ) strains of gram‐negative bacteria ,and 10(4 .3% ) strains of fungi;Escherichia coli ,the coagulase‐negative Staphylococcus ,Klebsiella pneumoniae and E .faecalis were ranked the top four species of pathogens ,accounting for 48 .9% ,13 .0% ,9 .5% ,5 .2% ,respectively .MRCNS among CNS were 73 .6% .Staphylococcus had 100 .00% sensitivity to vancomycin and linezolid ;the antimicrobial resistance rate of E .fae‐calis to ampicillin was 8 .3% .E .faecalis had 100 .00% sensitivity to vancomycin and linezolid .the detectable rates of Escherichia co‐li ,Klebsiella pneumoniae of ESBLs were 52 .2% and 50 .0% ,and the strains had 100 .00% sensitivity to imipenem and meropenem . Conclusion Escherichia coli is a major pathogen in urine culture ,Bacterial resistance is serious .
