Abstract:
OBJECTIVE To investigate the distribution and resistance of pathogenic becteria isolated from inpatients with lower respiratory tract infection in Department of Gerontal Respiratory Medicine during from Aug 2006 to Aug 2007.METHODS All the clinical isolates from sputum were analyzed retrospectively.RESULTS There were 211(79.8%) strains of Gram-negative bacilli,40(15.2%) strains of Gram-positive bacteria and 12(6%) strains of fungi.The most important Gram-negative pathogens were Klebsiella pneumoniae.Pseudomonas aeruginosa,Enterobacter cloacae and Escherichia coli.Strains of Gram-negative bacteria were susceptible to imipenem,cefoperzone/sulbactam and amikacin,strains of Gram-positive pathogens were susceptible to vancomycin,nitrofurantoin,cefazolin and imipenem.CONCLUSIONS Gram-negative bacilli are the major pathogens in lower respiratory tract infection in Department of Gerontal Respiratory Medicine and the dominant is conditional pathogen.Rational use of antibiotics is important for the containment of bacterial resistance.
