The prevalence of antibody to bovine respiratory syncytial virus in Quebec and the role of the virus in a respiratory disease outbreak was investigated. The indirect immunofluorescent, neutralization and haemagglutination inhibition techniques were used to carry out this study. Of the 1,444 adult animals examined 519 (35.9%) had antibody to bovine respiratory syncytial virus. These positive reactors were found in each agricultural region of Quebec. The highest (53.0%) and the lowest (21.8%) prevalence was observed in the sera collected by the laboratories of St. Hyacinthe and Sherbrooke. During a respiratory disease outbreak affecting 77 calves on a farm, bovine respiratory syncytial virus was shown to be associated with infectious bovine rhinotracheitis, bovine parainfluenza type 3, bovine viral diarrhea viruses and bovine adenovirus type 3 as detected by seroconversion. Of the 38 seroconverted animals 14 were seropositive to bovine respiratory syncytial virus.
对魁北克省牛呼吸道合胞病毒抗体的流行情况以及该病毒在一次呼吸道疾病暴发中的作用进行了调查。采用间接免疫荧光、中和及血凝抑制技术开展此项研究。在检测的1444只成年动物中，519只（35.9%）有牛呼吸道合胞病毒抗体。这些阳性反应动物见于魁北克的各个农业地区。在圣阿辛特和舍布鲁克实验室采集的血清中，抗体流行率最高（53.0%），最低（21.8%）。在一个农场发生的一次影响77头犊牛的呼吸道疾病暴发期间，通过血清转化检测发现，牛呼吸道合胞病毒与牛传染性鼻气管炎、牛副流感3型、牛病毒性腹泻病毒及牛腺病毒3型有关。在38只发生血清转化的动物中，14只对牛呼吸道合胞病毒呈血清阳性。
