| Objective To investigate the composition of pathogens and the relative diseases of children's community acquired persistent pneumonia. Methods Collect the blood?nasopharyngeal secretions?pleural effusions from children with the community acquired persistent pneumonia who hospitalized in our hospital between the year 2003.1 and 2008.1, and then test these collections to found the pathogens of them, and investigate it's relative diseases ,and analyze the relationship between the ages,nations,seasons,gender with the pathogens. Results we detected 132 pathogens that contain 40 cases (30.30%) of mycoplasma(MP), 12 cases (9.09%)of Chlamydia (CP), 43 cases (32.58%) of viruses, 33 cases (25.00%)of bacterias. Adenovirus (ADV), RS virus(RSV), EB virus play a important role in these viral pathogens, and so do pneumonia Klebsiella, legionella pneumophila, pseudomonas aeruginosa in the bacterial pathogens. 77 patients have incorporated diseases. Conclusions The main pathogens of children's persistent pneumonia are MP, CP, ADV, RSV, EBV.Alothough the detection rate of bacterias is low,In these pathogens, the infection of pneumonia Klebsiella,pseudomonas aeruginosa and legionella pneumophila (LP) are the main pathogens. There have relations between seasons,ages with these pathogens, but the nations and gender don't. In the relative diseases of the children's community acquired persistent pneumonia, the congenital heart disease and the diarrhea is much more common than malnutrition and the disease of foreign body in trachea. |
