Abstract:
OBJECTIVE To study the distribution and drug resistance supervision of infection pathogens of Gram-negative bacterial pneumonia in lower respiratory tract of senile patients and draft preventive and control measures.METHODS The sputum and lower respiration secretion of 368 senile patients were cultured to detect pathogens which were confirmed by routine methods.The disk diffusion test was adopted to analyze drug resistantce.RESULTS Pseudomonas aeruginosa rated the top one,reached 25.0%;the drug resistance supervision manifested that the resistant rates of Gram negative organisms to the routine drugs were high except for Haemophilus influenzae.And extensive-spectrum beta-lactamases(ESBLs) occurred with rate of 30.2%.CONCLUSIONS It is very necessary for clinical microbiology department to detect pathogens of lower respiratory tract pneumonia among senile patients and then to give reasonable advice for medicine in time.
