2011—2012年北京市顺义区猩红热病原学监测分析

Analysis on pathogenic surveillance of scarlet fever in Shunyi District of Beijing from 2011-2012

目的通过对发热皮疹性疾病病原学检测,为猩红热临床诊断提供病原学依据。方法对监测医院诊断为猩红热和"链球菌感染/扁桃体炎/咽峡炎"的309名病例咽拭子标本进行病原体的分离培养鉴定。结果从309份中咽拭子标本中,分离出乙型溶血性链球菌89例,阳性率28.80%。临床诊断为猩红热的病例,复核诊断阳性率只有54.05%;临床诊断为链球菌感染、扁桃体炎、咽峡炎病例的乙型溶血性链球菌阳性率分别为50.96%、8.63%及13.79%。结论医疗机构应开展猩红热的病原学检测,为临床诊断猩红热提供实验室依据,减少误诊和漏诊的发生。

[ Objective] To carry out the pathogenic detection of rash and fever illness, provide the pathogenic basis for clinical diag- nosis of scarlet fever. [ Methods] The throat swab specimens from 309 patients who were diagnosed with the streptococcal infection, tonsillitis and angina in surveillance hospital were collected, to isolate and identify the pathogens. [ Results ] Among 309 throat swab specimens, 89 strains of 13-hemolytic streptococcus were isolated, with the positive rate of 28.80%. Among cases of scarlet fever in clinical diagnosis, the positive rate in reexamination was only 54.05%. Among cases of streptococcal infection, tonsillitis and angi- na in clinical diagnosis, the positive rate of ^-hemolytic streptococcus was 50. 96%, 8. 63% and 13. 79%, respectively. [ Conclusion]The medical institutions should carry out the pathogenic detection of scarlet fever, to provide the etiology basis for clinical diagnosis of scarlet fever, and reduce the misdiagnosis and missed diagnosis.
