Abstract:
OBJECTIVE To study the constituent ratio and drug resistance of Gram-negative bacilli to draft preventive and control measures.METHODS The sputum and lower respiration secretion of 354 patients infected with Gram-negative bacilli were cultured by routine methods.Disk diffusion test was used to analyze drug resistance.RESULTS The isolating rate of Pseudomonas aeruginosa(25.7%) was the highest.Then was Klebsiella pneumoniae,accounted for 21.5%.Except for Haemophilus influenzae,the other Gram-negative bacilli were resistant to the routine drugs in different degrees.The detection rate of extensive-spectrum beta-lactamases(ESBLs) producers in K.pneumoniae and Escherichia coli were 38.2% and 36.7%,respectively.CONCLUSIONS It is very necessary for clinical microbiology department to monitor pathogens to provide the scientific evidence for clinical usage of the antibiotics.
