Pathogenic Bacteria in Hospital:Distribution and Drug Resistance of 1 213 Strains / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To determine the distribution of bacterial flora in hospital infection and to provide laboratory(evidence) for controlling hospital infection and selecting rationally antibiotics in clinic practice.METHODS All(isolates) were identified by routine procedure.MRSA and ESBLs-producing rate of Escherichia coli and Klebsiella pneumoniae were(examined.) RESULTS Among all these clinical infectious specimens,there were 202 strains of Gram negative bacilli,(accounting) for 40.9%(202/495);166 strains of fungi,accounting for 33.5%;621 strains of Gram positive cocci,for 20.6%(102/495).Candida albicans,E.coli,Pseudomonas aerugionosa,C.tropicalis and C.glabrata took the first five bacteria in infection.Analysis of drug resistant bacteria suggested that the isolated rate of ESBLs-producing strains in Staphylococcus aureus be 47.6%,be CNS in MRCNS 78.1% and MRSA in SA be 42.3%.CONCLUSIONS Multidrug resistance and fungus infection are the main risk factors in our hospital.We must improve means of treatment on clinical work and use antibiotic rationally to reduce the infection rate.
