RESUMO
Acinetobacter baumannii.Sixty(20.6%) strains of Gram-positive bacteria were isolated.Staphylococcus aureus was the most predominat pathogen(13.0%),meticillin-resistant S.aureus(MRSA)(72.8%).Twenty-nine(10.0%) strains of fungi were isolated,Candida albicans was the most predominant(7.56%).The result of drug sensitive test showed that there were high rates of multiple drug resistance in most bacteria strains,but there were high different drug resistance rates to different antibiotics.Ampicillin had the highest resistance rate nearly 100%.In contrast,the imipenem resistance had the lower resistance rate from 0-14.3%.Lactamases(ESBLs) in K.pneumoniae and E.coli were 56.5% and 41.2%. CONCLUSIONS Gram-negitive bacteria are major pathogens in pneumonia of aged.There are high rates of multiple drug resistance in bacteria strains.The clinic should reasonably choose the antibiotics according to the test results of the pathogens sensitivity to drugs.
