Pathogenic Bacteria Distribution and Drug Resistance of Hospital Infection in Pediatrics Unit / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the major pathogenic bacteria and drug resistance of hospital infection in pediatrics unit,and to provide laboratory evidence for clinical diagnosis and treatment.METHODS Pathogenic bacteria were isolated from patients who suffered from hospital infection in pediatrics unit from 2004 to 2006.the method was taken to carry out the sensitive test and bacteria identification by VITEK32,Streptococcus pneumoniae,Moraxella catarrhalis and Haemophylus influenzae were assayed with French Bio-Merieux API System ATB STREP5 and ATB HAEMO,respectively.RESULTS Totally isolated strains were 489.Of them,108 strains of coagulase negative Staphylococcus(CONS),being 22.1%.58 strains were S.haemolyticus.The isolated rate of CONS was 53.7%.The drug test for meticillin-resistant coagulase negative Staphylococcus(MRCNS) showed multiple drug-resistance.The detection rate of the ESBLs from the Escherichia coli and the Klebsiella pneumoniae was 18.9% and 12.5%,respectively.CONCLUSIONS MRCNS are the major pathogens in pediatrics unit.The detectable rate of MRCNS is high.Glycopeptide antibiotics are the first-choice drugs for MRCNS infection.
