呼吸道合胞病毒(RSV)和3型副流感病毒是婴幼儿下呼吸道感染的主要病因,而RSV尤为多见。本文报道6例婴儿在RSV流行季节感染3型副流感病毒。3型副流感病毒感染主要在2个月以内的婴儿发生,表现为严重的下呼吸道疾病症状,有窒息及心动过缓,其RSV快速诊断试验为阴性。方法及结果取一定量无菌生理盐水滴入鼻腔,然后经吸引装置取回。分泌物经病毒培养,使用荧光素标记的抗血清测定RSV。经猴肾细胞混悬物对副流感病毒进行初步检测,最后用特异性抗体测定。1984,10,1～1986,5,30.6例3型副流感病毒感染均发生于RSV流行季节。男女各3名,其中5名反
Respiratory syncytial virus (RSV) and parainfluenza virus type 3 are the major causes of lower respiratory tract infections in infants and young children, and RSV is particularly prevalent. This article reports 6 infants infected with RSV type 3 parainfluenza virus in the season of RSV. Type 3 parainfluenza virus infections occur in infants <2 months old and present with severe symptoms of lower respiratory tract disease, asphyxia and bradycardia, and their RSV rapid diagnostic test is negative. Methods and Results Take a certain amount of sterile saline drip into the nasal cavity, and then retrieved by the suction device. The secretions were virus-cultured and RSV was measured using fluorescein-labeled antiserum. The parainfluenza virus was preliminarily detected by the suspension of monkey kidney cells and finally detected with specific antibodies. 1984,10,1 ~ 1986,5,30.6 cases of type 3 parainfluenza virus infection occurred in the RSV epidemic season. 3 men and women each, of which 5 were anti
