Objective To explore the epidemiology of Ig Mantibodies of nine species of respiratory tract pathogens in 908 Patients. Methods Nine of pathogen Ig Mantibodies in serum of 908 Patients diagnosed as respiratory tract infections were tested by indirect immunofluorescence assay. Results Of total 908 serum specimens detected,there were 328 positive with the positive rate of 36. 1%. The rate of combined infection was 13. 4%( 122/908) in 908 Patients,37. 2%( 122/328) in positive cases. The combination of INFB and PIVS was most common. During spring and summer,it was dominated by the Influenza B( INFB),which was dominated by Parainfluenza1,2 and 3( PIVs). The positive rates of different pathogens were statistically significant in different seasons( P 0. 05). The positive rate in autumn and winter was higher than which in spring and summer. The patients aged less than 25 years and more than 65 years were the most susceptible to INFB,while the patients aged from 26 to 64 years were the most susceptible to Legionella pneumophila serogroup 1( LP1). The positive rate of the three groups was significantly different( P 0. 05). The positive rates of different pathogens were significantly different in different sex( P 0. 05). Conclusion To achieve the better protection and to prevent the prevalence and spread of the corresponding pathogens in their peak seasons,continuous monitoring of pathogen Ig Mantibodies is important.
