855例呼吸道感染患者九种病原体IgM抗体检测结果分析

Study on Nine Kinds of IgM Antibodies Tests of Respiratory Pathogens in 855 Patients with Respiratory Tract Infection

采用间接免疫荧光法(IFA)对855例呼吸道感染患者同时检测九种病原体的IgM抗体.结果表明,本地区呼吸道感染患者血清IgM检测总阳性率为39.88%(341/855),病原体主要为肺炎支原体(MP,17.19%)、乙型流感病毒(IFVB,8.77%)和呼吸道合胞病毒(RSV,5.26%),以单一感染为主(88.86%).<18岁年龄组的阳性率为46.30%,与其他年龄组相比有统计学差异(P<0.05).呼吸道感染好发于秋冬两季,秋冬季节的病原体感染率与其他季节相比,差异有统计学意义(P<0.05).采用IFA检测可掌握本地区呼吸道感染的流行病学特点和发病率,为临床诊断和治疗提供科学依据.

855 patients of respiratory tract infection in our hospital were collected,and the serum were detected by indirect immunofluorescence assay（IFA）for IgM antibodies′nine major pathogens.The results showed that the total positive rate was 39.88%（341/855）in 855 patients.And the main pathogens were MP（17.19%）、IFVB（8.77%）and RSV（5.26%）.Moreover,the main infection was single infection（88.86%）.The positive rates had significant difference（P〈0.05）between〈18age group and the other age groups.Respiratory tract infection was popular in autumn and winter,and the positive rates had significant difference（P〈0.05）between autumn,winter and spring,summer.
