收集儿科门诊及因呼吸道感染住院的成年患者血清,采用明胶颗粒凝集法检测肺炎支原体(MP)特异性抗体。结果 110例1~14岁儿童MP-IgM抗体阳性65例,阳性率59.09%,其中1~3岁、4~6岁和7~14岁患儿阳性率分别为45.24%、65.38%和69.05%。102例≥15岁的呼吸道感染者MP-IgM抗体阳性27例,阳性率为26.47%,其中15~45岁、46~75岁和≥76岁组阳性率分别为64.71%、26.47%和13.72%。呼吸道MP各年龄段儿童普遍易感,有低龄化发展趋势,成人易感年龄范围有扩大趋势。
Serum collected from pediatric outpatients and hospitalized adult patients with respiratory infection was collected. Gelatin particle agglutination was used to detect mycoplasma pneumoniae (MP) specific antibodies. Results The positive rate of MP-IgM antibody in 110 children aged 1-14 years was 59.09%, of which 45.24%, 65.38% and 69.05% respectively. The positive rates of MP-IgM antibody in children aged 1 to 3 years, 4 to 6 years and 7 to 14 years were 110, . The positive rate of MP-IgM antibody in 102 patients aged 15 years or older with respiratory infection was 26.47%. The positive rates of MP-IgM antibody were 64.71%, 26.47% and 13.72% in 15-45, 46-75 and 76- . Respiratory MP children of all ages are generally susceptible, with the development trend of younger age, adult susceptible age range has expanded.
