目的为进一步了解呼吸道感染病原菌学的变化。方法应用回顾性调查分析方法，对我院６年来呼吸道感染的病原菌作了统计分析。结果５３８０例呼吸道感染患者中，Ｇ－杆菌２５５２株，占４７．４％，其中大肠埃希氏菌、产气杆菌和铜绿假单胞菌分别占２３．４％、２３．２％、１４．６％；Ｇ＋球菌１８０７株，占３３．６％；微球菌４０４株，占７．５％。结论呼吸道感染的主要致病菌为Ｇ－杆菌，微球菌感染的比例有上升的趋势。
Objective To further understand the pathogens of respiratory tract infections. Methods Retrospective investigation and analysis methods, the hospital for 6 years of respiratory tract infection caused by pathogenic bacteria were analyzed. Results Among the 5380 cases of respiratory infections, 2552 strains of G-bacilli accounted for 47.4%, of which Escherichia coli, Aerobacter aerogenes and Pseudomonas aeruginosa accounted for 23.4% and 23.2% respectively. 6%; 180 strains of G + cocci, accounting for 33.6%; Micrococcus 404 strains, accounting for 7.5%. Conclusion The main pathogen of respiratory tract infection is G-bacilli, and the proportion of micrococcal infection is on the rise.
