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 provide etiological evidence for clinical diagnosis of scarlet fever by etiological detection of fever rash disease. Methods Thirty-nine throat swabs diagnosed as scarlet fever and “streptococcal infection / tonsillitis / angina” in the hospital were identified for pathogen isolation and culture. Results From 309 samples of pharyngeal swabs, 89 cases of hemolytic streptococcus were isolated, the positive rate was 28.80%. The clinical diagnosis of scarlet fever cases, the positive rate of diagnosis was only 54.05%; clinical diagnosis of streptococcal infection, tonsillitis, angina cases of hemolytic streptococcus B positive rates were 50.96%, 8.63% and 13.79%. Conclusion The medical institutions should carry out the etiological examination of scarlet fever to provide laboratory evidence for the clinical diagnosis of scarlet fever and reduce the occurrence of misdiagnosis and missed diagnosis.
