Analysis of Pathogenic Bacteria in Lower Respiratory Tract Infection

Objective To investigate the distrubution of pathogenic bacteria in lower respiratory tract infection in hospital.Methods Used the combination of prospective with retrospectivestudy 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% in2000.Conclusion Should strongly control the infections of opportunist pathogen in patients of lower respiratory tract infection,for example,mycetes,nonfennenter et al.
