Abstract:
OBJECTIVE To investigate the distribution and drug resistanc of nosocomial infection pathogens from lower respiratory tract in senile patients in different season.METHODS The sputum samples from lower respiratory tract infection in senile patients in two years,were collected to identify pathogens and drug sensitivity test j udged according to NCCLS standard.RESULTS The gram-negative bacilli accounted for 85.7%.The gram- posutive bacilli accounted for 14.3%.The predominant pathogens were Pseudomonas aeruginosa(20.3%),Kleb- siella pneumoniae(14.5%),Acinetobacter lwof fi(9.8%),coagulase-negative staphylococci(9.0%).The distribution and antibiotic-resistanc of main pathogens had different characteristics in different season. CONCLUSIONS Understanding the characteristics of local pathogen spectruma and the antibiotic-resistanc of main pathogens in different season were signincant on prevention and therapy of the lower respiratory tract infection in senile patients.
