A serological survey was conducted in an attempt to detect antibodies against bovine respiratory viruses in sheep and goats from seven geographical areas of Quebec. Sera from 10% of the animals in 182 sheep flocks and 40 goat flocks were collected and specific antibodies against parainfluenza-3, reovirus type 3, respiratory syncytial and infectious bovine rhinotracheitis viruses were detected by hemagglutination-inhibition tests for the former viruses and complement fixation and seroneutralization assays for the latter viruses. Results showed prevalence rates of serological reaction to parainfluenza-3, reovirus type 3 and respiratory syncytial viruses of 28, 72 and 35% in sheep and 26, 64 and 36% in goats, respectively. No antibodies in infectious bovine rhinotracheitis virus were detected in sheep or goats tested. Prevalence rates varied according to the geographical area. No relationships were detected between age, sex, breed, size of flock and prevalence rates of different antibodies except that parainfluenza-3 antibodies were more common in large goat flocks and in sheep flocks with total confinement housing. A relationship between presence of clinical signs in the flocks and prevalence rates of antibodies was only demonstrated for parainfluenza-3 infection in goat flocks.
在魁北克七个地理区域的绵羊和山羊中进行了一项血清学调查，以检测抗牛呼吸道病毒的抗体。从182个绵羊群和40个山羊群中10%的动物采集血清，通过血凝抑制试验检测抗副流感3型、3型呼肠孤病毒、呼吸道合胞病毒的特异性抗体，通过补体结合试验和血清中和试验检测抗传染性牛鼻气管炎病毒的特异性抗体。结果显示，绵羊对副流感3型、3型呼肠孤病毒和呼吸道合胞病毒的血清学反应患病率分别为28%、72%和35%，山羊分别为26%、64%和36%。在检测的绵羊或山羊中未发现抗传染性牛鼻气管炎病毒的抗体。患病率因地理区域而异。除了在大型山羊群和完全封闭饲养的绵羊群中副流感3型抗体更常见外，未发现年龄、性别、品种、羊群大小与不同抗体患病率之间的关系。仅在山羊群中证明了羊群中临床症状的存在与抗体患病率之间的关系，即副流感3型感染。
