Analysis of Pathogen Features on Aged Patients With Lung Infection

Objective To understand the pathogen features and resistance for drug in aged patients with lung infection. Methods The isolated culture were used for sputum samples. The bacteria was distinguished by API bacteria identification instrument. ATB paper was used for drug sensitive test. Results The Gram negative bacillus, Gram positive coccus and fungus were 59.4%, 26.7% and 13.9% respectively. The Pseudomonas, K.pneumoniae and Acinebacter were main bacteria in Gram negative bacillus. The enterbactericae had high sensitive for lmipenem. The staphylococcus aureus was main bacteria in Gram positive coccus in which resistance for vancomycin was not found. Conclusion The severe and complex clinic symptoms were often observed in aged patients with lung infection. These patients have high mortality. Correct and reasonable treatment depend on drug resistance test.
