Abstract:
Objective To investigate the pathogens distribution in neonatal blood culture and their drug resistance to antibacteri‐al drugs in Dalian City .Methods The routine blood culture ,identification and drug sensitivity test were carried out in the hospital‐ized neonates from August 2014 to August 2015 .And the obtained data were analyzed .Results A total of 186 strains of pathogenic bacteria were detected from 1 570 cases of neonatal blood culture and the positive rate was 11 .8% .Gram positive bacteria accounted for 74 .2% (138/186) and were dominated by Staphylococcus epidermidis .Gram negative bacteria accounted for 25 .3% (47/186) , which were mainly onion burkholderia bacterium .One strain was fungus ,accounting for 0 .5% .The drug sensitivity test results showed that Gram positive bacteria had the higher resistance rate to penicillin and erythromycin (80 .0% -90 .0% ) ,100 .0% sensi‐tivity to vancomycin ,linezolid and teicoplanin ;E .coli and K .pneumoniae had the highest resistance rate to ampicillin (88 .2% -100 .0% ) ,100 .0% sensitivity to imipenem ,amikacin ,low resistance rate to piperacillin/tazobactam ,cefoperazone/sulbactam ,amoxi‐cillin/clavulanic acid ,cefepime and ceftazidime (0% -10 .0% ) .The resistance rate of onion burkholderia bacterium to ticarcillin/clavulanate and meropenem was higher than 80 .0% ,which had 100 .0% sensitivity to cefoperazone /sulbactam ,levofloxacin ,mino‐cycline and compound sulfamethoxazole .Conclusion The neonatal blood culture pathogen in Dalian City is dominated by Gram pos‐itive bacteria ,coagulase negative staphylococcus is the main pathogen .Due to the different regional environmental ,pathogens and drug resistance should be regularly monitored and analyzed to provide objective and accurate basis for clinical rational use of anti‐bacterial drugs .
