Abstract:
OBJECTIVE To investigate the distribution and drug resistance of nosocomial infection pathogens from lower respiratory tract in senile patients. METHODS The sputum and lower respiratory tract secretion in the senile patients with lower respiratory tract infection were collected nearly five years,and identified.The drug sensitivity test,the results of examination were judged according to NCCLS standard. RESULTS The Gram-negative bacilli accounted for 79.5%.The Gram-positive bacteria accounted for 20.5%.The predominant pathogens were Pseudomonas aeruginosa(19.6%),coagulase-negative Staphylococci(CNS)(18.7%),and acinetobacter lwoffi(11.6%).The resistant bacteria were markedly increasing. CONCLUSIONS The Gram-negative bacilli are the major pathogens in the senile deceased patients.The incidence of CNS infection is markedly increasing.The isolating rate of meticillin-resistant CNS is 100.0%.
