Abstract:
OBJECTIVE To analyze distribution and resistance of bacteria from lower respiratory tract infection in elderly patients,and provide reference for rationl use of agents in clinics.METHODS To collect phlegm specimens from lower respiratory tract infection in elderly patients from Jan 2003 to Jun 2005 in our hospital,to identify pathogens and drug sensitivity test,the results of examination were judged according to NCCLS standard.RESULTS Among 752 pathogens strains,Gram-negative bacteria and Gram-positive cocci were 70.9% and 17.6%,respectively;the most common pathogens of them were Klebsiella pneumoniae(ESBLs 27.7%)14.89%,Pseudomonas aeruginosa 14.36%,Escherichia coli(ESBLs 35.4%)12.77%,Staphylococcus aureus(MRSA 59.0%)11.70%,and fungi 11.57%.CONCLUSIONS The bacteria from lower respiratory tract infection in elderly patients are distributed extensively.In Gram-positive cocci,resistance to vancomycin is not found elsely.Gram-negative bacteria are especially sensitive to imipenem,but with some resistant strains.
