Pathogens and Their Antimicrobial Resistance in 105 Children with Community-acquired Bacteremia / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To determine the pathogenic distribution and antimicrobial resistance of community acquired bacteremia in 105 children patients.METHODS Clinical profile,results of blood culture and antibiotic susceptibility test of 105 patients with community-acquired bacteremia treated from Jan 2003 to Dec 2006 were studied retrospectively.RESULTS The Gram-positive bacteria were from 58 cases which accounted for 55.2%.Most of them were Staphylococcus epidermidis,S.haemolyticus and S.hominis.The positive rate was 19.0%,15.5% and 10.3%,respectively.The Gram-negative bacilli were seen from 47 cases which accounted for 44.8%.Escherichia coli,Stenotrophomonas maltophilia and Klebsiella pneumoniae were the main microrganism in Gram-negative bacilli,the positive rate was 19.1%,14.9% and 10.6%,respectively.The resistant rate of Staphylococcus to penicillin was 100%.Their resistant rate to erythromycin was 94.7%.100% Gram-positive bacteria were susceptible to vancomycin,most of them were susceptible to ciprofloxacin,rifampicin and nitrofurantoin.The resistant rate of Gram-negative bacilli to ampicillin was 91.7%.Most of Gram-negative bacilli were susceptible to the third generation cephlosporin plus enzyme inhibitor,ciprofloxacin and imipenem.Resistance of the isolated pathogens to several commonly used antibiotics in pediatrics was observed.CONCLUSIONS We must focus on children aged under 3 years who are at risk of developing bacteremia.Empirical treatment with antibiotics is recommended only in life-threatening sepsis cases in pediatric emergency department.
