Sera from 187 (42%) of 447 free-ranging bighorn sheep (Ovis canadensis) in 9 western states had antibody titers to respiratory syncytial virus (RSV). Titers were from 1:5 to 1:640, as determined by the standard virus neutralization test. Results of the survey indicated that RSV is widespread in free-ranging bighorn sheep populations and that RSV may be an important factor in the bighorn sheep pneumonia-complex.
来自美国西部9个州的447只野生大角羊（加拿大盘羊）中，187只（42%）的血清对呼吸道合胞病毒（RSV）具有抗体效价。通过标准病毒中和试验测定，效价范围为1:5至1:640。调查结果表明，RSV在野生大角羊种群中广泛存在，并且RSV可能是大角羊肺炎综合征的一个重要因素。
