The significance of combined detection of 9 IgM antibodies of pathogens in patients with respiratory tract infection in Huidong area

Objective To investigate infection rates of different pathogens in patients with respiratory tract infection and its epi‐demic characteristics .Methods The 818 serum specimens were collected from children with respiratory tract infection .And IgM antibodies of nine main pathogens ,including Legionella pneumonia(LP) ,Mycoplasma pneumonia(MP) ,Coxiellaburnetii(COX) , Chlamydiapneumoniae(CP),adenovirus(ADV),respiratory syncytial virus(RSV),influenza A virus(IFA),influenza B virus(IFB) and parainfluenza virus(PIVS) type 1 ,2 and 3 ,were detected by using nine respiratory joint inspection reagent (indirect immunoflu‐orescence) .Results The total infection rate of nine kinds of pathogens was 30 .9% ,of which the MP infection was the most com‐mon ,followed by IFB infection and RSV infection .The mixed infection rate was 7 .7% .Conclusion The main pathogens for respir‐atory tract infection in childen in this region might be MP,IFB and RSV .Investigating pathogens of respiratory tract infection could be helpful for rational use of antibacterials .
