应用已知抗体检测104例支气管肺炎（瑞型）患儿鼻咽分泌物脱落细胞内的病毒抗原。检测到的病毒包括呼吸道合胞病毒、流感病毒A型和B型。阳性病例可为单一病毒感染或几种病毒合并感染，病毒感染阳性率为60．6％，感染阳性率以呼吸道合胞病毒最高。病毒感染后发生的气道高反应与其感染及临床症状的严重程度、持续时间呈平行关系。病毒早期快速诊断可为支气管肺炎的治疗提供可靠的病原学依据。
Known antibodies were used to detect 104 cases of bronchial pneumonia (Rui type) nasopharyngeal secretions exfoliated cells within the virus antigen. Viruses detected include respiratory syncytial virus, influenza A and B viruses. Positive cases may be a single virus infection or several virus co-infection, the positive rate of virus infection was 60.6%, the highest positive rate of respiratory syncytial virus. After the virus infection occurs airway hyperresponsiveness and its infection and the severity of clinical symptoms, the duration of a parallel relationship. Early rapid diagnosis of the virus can provide a reliable etiological basis for the treatment of bronchial pneumonia.
