RESUMO
Objective To analyze the detection rates and quarterly distribution status of 8 respiratory pathogens of IgM antibody in patients with pulmonary infection,in order to provide a basis for clinical treatment and prevention.Methods A total of 384 ser-um samples of patient with pulmonary infection in Rehabilitation Hospital affiliated to Fujian University of TCM from April 2014 to March 201 5 were collected,and indirect immunofluorescence assay (IFA)was applied to detect 8 respiratory pathogens IgM anti-bodies.Results The positive rate of respiratory pathogens IgM antibody in patients was 13.54% (52/384),and the positive rate of influenza A and influenza B both were 4.43% (1 7/384).The highest infection rate about 8 respiratory pathogens was in the first quarter,and the infection of influenza A and B virus is the most common.Chronic obstructive pulmonary disease complicated with pulmonary infection in patients with IgM antibody positive rate was significantly higher than that of other patients with pulmonary infection,positive detection rates in the first quarter and four quarter were higher than in other seasons.Conclusion The 8 respira-tory pathogens in IgM antibody detection is important significance for the early diagnosis of pulmonary infection.We should do a good job in the prevention of respiratory viruses and atypical pathogens in popular time.
