下呼吸道感染患者临床分离病原菌的分析

Analysis of Pathogenic Bacteria in Lower Respiratory Tract Infection

目的了解医院下呼吸道感染患者临床分离病原菌的分布情况。方法采用前瞻性研究和回顾性调查相结合的方法，对2000年～2003年临床下呼吸道感染患者痰培养阳性结果进行分析。结果下呼吸道感染以60y以上患者为主，达到69.1％,病原菌前五位分别是真菌（27．5％）、葡萄球菌属（19．6％）、假单胞菌属（15．9％）、克雷伯菌属（6．8％）、不动杆菌属（5.4％），真菌感染由2000年的15．2％上升到2003年的32．5％。结论在对下呼吸道感染患者的治疗中，临床应加强对真菌、非发酵菌等机会致病菌感染的控制。

Objective To investigate the distrubution of pathogenic bacteria in lower respiratory tract infection in hospital. Methods Used the combination of prospective with retrospective study to analyze the clinical data of sputum culture positive in lower respiratory tract infection from 2000 to 2003 in hospital. Results Patients over 60 years old added up to 69. 1% in lower respiratory tract infection. Pathogenic bacteria in front of the fifth was Mycete （27.5%）,Staphylococcus （19. 6 % ）, Pseudomonas （15.9 % ）, Klebsiella （6.8 % ） and Acinetobacter （5.4 % ）, respectively. Mycotic infection added up to 32. 5% in 2003 from 15.2% in 2000. Conclusion Should strongly control the infections of opportunist pathogen in patients of lower respiratory tract infection ,for example ,mycetes ,nonfennenter et al.
