摘　　要：目的:了解我科下呼吸道感染患者痰标本的细菌分布,以指导我科医生合理用药。方法:对我科住院的下呼吸道感染患者痰培养检出的220株病原菌的分布进行分析。结果:痰培养阳性率为31%。在检出的220株病原菌中,G-性杆菌125株,占57%;G+性球菌84株,占38%;真菌11株,占5%。结论:我科住院的下呼吸道感染患者的致病菌仍以G-杆菌为主。真菌感染占有一定比例,应引起我科医生的重视。Objective： To investigate the bacterial distribution in patients with respiratory tract infection,and provide evidence for using antibiotics.Methods： The distribution of 220 strains of pathogens detected from sputum culture of patients with respiratory tract infection was analyzed.Results： The positive rate of sputum culture was 31%.In total of 220 strains of bacteria,Gram-negative bacilli was 125 strains,and the percentage was 57%;Gram-positive cocci was 84 strains,and the percentage was 38%;fungus was 11 strains,and the percentage was 5%.Conclusions： Gram negative bacilli were the main pathogens in hospitalized patients with lower respiratory tract infection.Fungal infection was found in a certain proportion,and this must cause our attention.
