ABSTRACT
Objective This study was provided the evidence of infection respiratory tract clinical treatment through examining 695 cases of pathogen .Methods Using indirect immunofluorescence(IFA) IgM antibody with 9 respiratory pathogen in serum of 695 patients from August 2015 to March 2016 with respiratory tract infection from espiratory ,pediatrician ,thoracic surgery clinics were detected in this paper in order to provide the basis for clinical treatment .Results The results showed that single pathogen de‐tection positive rate was 33 .9% in 695 cases ,The top three of positive rate were MP(14 .1% ) ,IFB(9 .6% ) ,RSV(4 .8% );the posi‐tive rate of two mixed infection was 7 .79% ;The postive rate of MP ,IFB have obvious difference in seasons ,but which of Coxiella burneti was no obvious seasonal difference;there was an obvious difference between the sex ratio .Conclusion MP ,IFB ,RSV infec‐tion were given priority to detection rate in our region .
