ABSTRACT

Objective To analyze the results of children′s respiratory tract infection pathogens IgM antibody nine‐combined de‐tection in Pu′er and grasp the epidemiological characteristics of respiratory tract infection of local children for providing reference for clinical diagnosis and treatment .Methods 1 327 cases of children′s blood sample with respiratory tract infection were randomly sampled from in Pu′er People′s Hospital in 2014 .All the samples were tested with nine respiratory tract infection pathogens IgM antibody detection reagent kit(indirect immunofluorescence) ,and the test results were adopted for statistical analysis .Results There were 446 cases positive for IgM antibody in 1 327 cases of respiratory tract infection children ,the total positive rate was 33 .6% .The Positive rate of mycoplasma pneumonia(MP) was the highest ,for 23 .6% .The second was influenza B virus(INFB) , for 18 .5% .The eosinophilic lung legionella type 1(LP) ,adenovirus(ADV) ,respiratory syncytial virus(RSV) ,influenza A(INFA) and parainfluenza virus(HPIVs) were all much lowerrespectively for 0 .4% ,1 .1% ,1 .0% ,1 .1% and 1 .0% .It was showed that no positive results were found in Q fever rickettsia(CB) and chlamydia pneumonia(CP) .There was significant difference of the positive rate among 9 kinds of pathogens(P<0 .05) .There was significant difference of the monthly positive rate among the main six patho‐gens(P<0 .05) .There was significant difference of the positive rate in the different age groups(P<0 .05) .Conclusion The respir‐atory tract infection pathogens of children in Pu′er are mainly mycoplasma pneumoniae and influenza B virus .The epidemiological distribution of the pathogens is related to the age and season ,the clinician should reasonably diagnose and treat according to the test results for children .
