ABSTRACT

Objective To compare and analyze the detection situation of common pathogens in child respiratory tract infection in our hospital and to provide the basis for clinical accurate diagnosis and reasonable treatment .Methods A total of 6 032 specimens were collected from the children patients with acute respiratory tract infection in the Gansu Provincial Maternity and Child Health Care Hospital from January to December 2015 .The immunodot test technology was adopted to detect the 6 kinds of early specific serum antibody IgM of common respiratory pathogensadenovirus (ADV ) ,influenza virus (IV ) ,parainfluenza (PIV ) ,respiratory syncytial virus (RSV) ,mycoplasma pneumoniae (MP) and chlamydia pneumonia (CP) .The differences in children infection pat‐terns ,different ages ,seasons and genders were analyzed .Results Among 6 032 specimens ,2 279 cases were positive with the posi‐tive rate of 37 .8% .The positive rates of 6 kinds of respiratory pathogens were in turn 12 .2% for ADV ,9 .6% for IV ,7 .9% for CP ,4 .6% for MP ,3 .0% for RSV and 0 .3% for PIV .The detection rate of respiratory tract pathogens was higher in spring and summer ;age groups of 1-3 years old and 4-6 years old had higher positive detection rate .Conclusion The main common patho‐gen of respiratory tract infection in this hospital is ADV ,followed by IV .Their infection has obvious seasonality .The mycoplasma and chlamydia also are the common pathogens of respiratory tract infection ,which are dominated by MP and CP .
