　　Analyze of Pathogen Distribution of Under Respiratory Way Infection of ICU and Internal Medicine Departments

　　Abstract：Objective To investigate the pathogen distribution of respiratory infection in patients in ICU and internal medicine departments,it is significant for empirical use of anti microbial agents in clinic. Methods Review the data of all patients who were hospitalized in ICU and internal medicine departments between August 2004 and August 2005.Results A total of 1 050 strains isolated from which the Gram-negative bacilli were predominate (51.6%):Gram-positive bacteria accounted for 21.4% and fungi for 27.0%.Conclusion It is so important to strengthen the checking out of pathogen of low respiratory infection in ICU and internal medicine dipartments that can guide the experiential treat.
