Abstract:
OBJECTIVE To investigate the distribution and drug resistance of pathogenic bacteria from lower respiratory tract infection in elderly patients.METHODS A total of 1739 strains of bacteria isolated from sputum and lower respiration secretion culture of the elderly patients were identified and their drug resistance was tested by K-B method.RESULTS From 1739 strains of pathogens isolated,Gram-negative bacilli accounted for 63.8%.The main Gram-negative bacilli were Escherichia coli and Pseudomonas aeruginosa,Acinetobacter baumannii,Enterobacter cloacae and Klebsiella pneumoniae.Gram-positive cocci accounted for 22.9% and Candida albicans accounted for 13.3%,respectively.The resistance rates of Gram-negative bailli to imipenem,cefoperazone/sulbactam and amikacine were relatively low.And all Gram-positive cocci were sensitive to vancomycin.CONCLUSIONS The antimicrobial resistance of pathogens in elderly patients with lower respiratory tract infection is serious.It is important to mornitor the antimicrobial resistance.
