目的:分析桂林市儿童肺炎支原体(MP)感染的流行情况。方法:采用血清被动凝集法对2011年1月～12月在桂林医学院第二临床医院住院的呼吸道感染患儿进行MP-IgM检测。结果:2011年共检测标本653份,总阳性率为25.27%;≤1岁、1～3岁、3～6岁、>6岁的患儿MP-IgM阳性率分别为9.20%、33.66%、33.04%、42.17%;男性患儿阳性率为21.43%,女性患儿阳性率为32.19%;春、夏、秋、冬四季阳性率分别为25.79%、17.61%、20.51%、35.88%。结论:MP已成为桂林市儿童呼吸道感染最常见的病原体之一,MP感染全年均有散发,以冬季感染率最高,婴儿感染率最低;女性儿童MP-IgM阳性率明显高于男性儿童。
Objective: To analyze the prevalence of Mycoplasma pneumoniae (MP) infection in Guilin children. Methods: MP-IgM was detected in children with respiratory tract infection who were hospitalized in the Second Clinical Hospital of Guilin Medical College from January to December 2011 by passive agglutination. Results: A total of 653 specimens were detected in 2011, with a positive rate of 25.27%. The positive rates of MP-IgM in children ≤1 years old, 1-3 years old, 3-6 years old and> 6 years old were 9.20%, 33.66% 33.04% and 42.17% respectively. The positive rate of male children was 21.43% and that of female children was 32.19%. The positive rates of spring, summer, autumn and winter were 25.79%, 17.61%, 20.51% and 35.88% respectively. CONCLUSION: MP has become one of the most common pathogens of respiratory tract infections among children in Guilin. The infection rate of MP was the highest throughout the year, with the highest infection rate in winter and the lowest infection rate in infants. The positive rate of MP-IgM in female children was significantly higher than that of male children.
