| 目的 了解9种呼吸道病原体在鄂东地区不同年龄段住院儿童中的分布特征,为临床精准性治疗提供病原学依据。 方法 检测呼吸道感染住院儿童2015年6月—2016年5月1 440例静脉采集血液,采用间接免疫荧光法(IFA)检测9种病原体抗体免疫球蛋白M(IgM),记录结果并行统计学分析比较。 结果 肺炎支原体(MP)、乙型流感病毒(INFB)、呼吸道合胞病毒(RSV)、腺病毒(ADV)、副流感病毒(PIV)、嗜肺军团菌(LP)检出率依次为22.71%、15.56%、5.07%、4.38%、3.13%、2.99%,Q热立克次体(COX)、 肺炎衣原体(CP)、甲型流感病毒(INFA)偶见；阳性率主要年龄特征为:MP:3.0～＜6.0岁占39.45%、1.0～＜3.0岁占35.47%, INFB:3.0～＜6.0 岁占48.22%、1.0～＜3.0岁占40.18%,RSV:1.0～＜3.0岁31.51%、0.5～＜1.0岁28.77%,ADV:1.0～＜3.0 岁33.33%、0.5～＜1.0岁及3.0～＜6.0 岁均为25.40%,PIV:1.0～＜3.0 岁53.33%、3.0～＜6.0 岁26.67%,LP:3.0～＜6.0 岁60.47%、1.0～＜3.0 岁27.91%； 混合感染占总阳性率的33.28%,多为MP参与的组合感染。 结论 MP和INFB是鄂东地区住院儿童呼吸道感染的主要病原体； 3.0～＜6.0岁年龄段住院儿童中MP、INFB、LP阳性比例最高,其次为1.0～＜3.0岁；RSV、ADV、PIV在1.0～＜3.0 岁住院呼吸道儿童中阳性比例最高；MP是鄂东地区住院儿童感染主要非典型病原体。 |

| Objective To know about the distribution characteristics about nine respiratory pathogens in the eastern area of Hubei,China among different ages of hospitalized children and to provide etiological basis for clinical precision treatment. Methods From June 2015 to May 2016,1 440 samples of venous blood in hospitalized children with the infection of the respiratory tract were collected to detect nine pathogens antibodies IgM by using indirect immunofluorescence (IFA) assay.The results were recorded and analyzed with statistical comparison. Results The detection rates of mycoplasma pneumoniae (MP),influenza Bvirus (INFB),respiratory syncytial virus (RSV),adenovirus (ADV),parainfluenza virus (PIV) and Legionella pneumophila (LP) were 22.71%,15.56%,5.07%,4.38%,3.13% and 2.99%,respectively,and Qheat Rickettsia (COX),Chlamydia pneumoniae (CP),influenza Avirus (INFA) were occasionally seen.The main age characteristics for the detection of positive rate were as follows:as for MP:age group between 3.0 and under the age of 6.0 accounted for 39.45%,and group between 1.0 to under the age of 3.0 accounted for 35.47%;as for INFB,group between 3.0 and under the age of 6.0 accounted for 48.22%,and group between 1.0 and under the age of 3.0 accounted for 40.18%;as for RSV,group between 1.0 and under the age of 3.0 accounted for 31.51%,and group between 0.5 and under the age of 1.0 accounted for 28.77%;as for ADV,group between 1.0 and under the age of 3.0 accounted for 33.33%,and group between 0.5 and under the age of 1.0 and between 3.0 and under the age of 6.0 accounted for 25.40%;as for PIV,group between 1.0 and under the age of 3.0 accounted for 53.33%,and group between 3.0 and under the age of 6.0 accounted for 26.67%;as for LPZ,group between 3.0 and under the age of 6.0 accounted for 60.47%,and group between 1.0 and under the age of 3.0 accounted for 27.91%.Mixed infection accounted for 33.28% of the total positive rate,which was mainly the infection with MP involved. Conclusions MP and INFB are the main pathogens of respiratory tract infection in children;the proportions of MP,INFB and LP were the highest among the hospitalized children aged 3.0 to under the age of 6.0,followed by1.0 to under the age of 3.0;the positive rates of RSV,ADV,PIV in the group from 1.0 to under the age of 3.0 hospitalized children with respiratory tract infection were the highest;MP is the main atypical pathogens infection in hospitalized children. |
