Abstract:
OBJECTIVE To analyze the pathogens of severe pneumonia induced by different underlying diseases in(hospital) and to evaluate the difference of the pathogens to antimicrobial susceptibility test.METHODS The(bacteria) through sputum culture with VITEK-AMS,and the antimicrobial susceptibility against(bacteria) by K-B method were tested in hospital from 2002 to 2005.RESULTS There were 106 patients with 173 strains of isolated(pathogenic) bacteria,including Klebsiella pneumoniae(KPA) 20.9%,and Escherichia coli(ECO)(16.3%) from the aspiration severe pneumonia;Pseudomonas alcaligenes(PAL) 18.9%,P.aeruginosa(PAL)(16.2%) and Staphylococcus aureus(SAU) 16.2% from the obstructive severe pneumonia;KPN 22.6%,SAU(18.9%),and PAE 17.0% from the COPD complicated with severe pneumonia and PAE 25.0% and SAU 20% from the(hospital-)acquired pneumonia(HAP).CONCLUSIONS The constructed ratio of pathogens is different between(severe) pneumonia infected by different underlying diseases and community-acquired pneumonia without any(underlying) disease.The resistant pathogens are increasing significantly in cases with HAP.
