2011—2014年北京市怀柔区猩红热病原学检测分析

Etiological detection and analysis on scarflet fever in Huairou District of Beijing from 2011-2014

目的了解近年来北京市怀柔区猩红热病原学检测对猩红热临床诊断的意义。方法对2011—2014年5—7月份怀柔区两家哨点医院猩红热病例咽拭子进行A群乙型溶血性链球菌分离培养和鉴定，结合猩红热流行病学资料进行分析。结果共检测964份咽拭子标本，分离出A群乙型溶血性链球菌60株，检出率为6．22％。2011—2014年各年度检出率分别为9．56％、12．69％、1．75％、4．40％。患者年龄为0～14岁，检出率最高的年龄组为6～12岁。不同临床诊断患者A群乙型溶血性链球菌检出率不同，猩红热、链球菌感染、扁桃体炎、咽峡炎病例病原检出率分别为22．22％、38．24％、4．32％、1．71％。结论猩红热病原学检测对订正临床诊断起到至关重要的作用。

[ Objective ] To study the clinical diagnostic significance of etiological detection of scarflet fever in Huairou District of Beijing in recent years. [Methods] The throat swab specimens were collected from the scarflet fever cases in two sentinel hospitals of Huairou District during the period of May to July from 2011-2014, to conduct the isolation and identification of group A beta hemolytic streptococcus, and the results were analyzed by combining with the epidemiological data of scarflet fever. [Results] 60 strains of group A beta hemolytic streptococcus were isolated from 964 throat swab specimens, with the detection rate of 6.22%. The annual detection rate from 2011-2014 was 9.56%, 12.69%, 1.75% and 4.40%, respectively. The patients were people aged 0-14 years old, and the detection rate in 6-12 year-old age group was the highest, The detection rates of group A beta hemolytic streptococcus were different in patients with different clinical diagnosis, and the detection rate in scarflet fever, streptococcal infection, tonsillitis and angina cases was 22.22%, 38.24%, 4.32% and 1.71%, respectively. [Conclusion] The etiological detection of scarflet fever plays a crucial role on correcting clinical diagnosis.
