Abstract:
OBJECTIVE To investigate the drug resistance and distribution of nosocomial infection(NI) pathogens.METHODS A total of 1 163 strains of NI pathogens during Jan 2002-Dec 2005 were completely surveyed and analyzed.RESULTS From them Gram-positive cocci were 376 strains(32.3%),the main pathogen was Staphylococcus aureus(12.7%),the average isolation rate of MRSA was 82.5%.Gram-negative bacilli were 474 strains(40.8%),the predominant pathogens were Escherichia coli(9.9%),Klebsiella pneumoniae(7.1%),Pseudomonas aeruginosa(5.4%),and Enterobacter cloacae(5.2%).The drug resistance of NI pathogens was markedly increased.Especially,the rates of drug resistance of P.aeruginosa to ceftazidime and imipenem were from 0 to 48.9% in 2005.CONCLUSIONS The Gram-negatives of NI pathogens are markedly increase year by year.The drug resistance rate of pathogens is higher,the clinically selected anti-bacterial drugs should be based on the bacterial culture and drug susceptibility test.
