Five cervid species in Oregon, USA were tested with a serum neutralization assay for antibody to deerpox virus (DPV). None of the 50 elk (Cervus elaphus ssp. roosevelti and nelsonii) had detectable antibody. Prevalence of antibody to DPV in the remaining species was: 52% (n=55) in black-tailed deer (Odocoileus hemionus columbianus), 32% (n= 59) in mule deer (O. hemionus hemionus), and 36% (n=50) in Columbian white-tailed deer (O. virginianus leucurus), with an overall antibody prevalence of 40.2% (n=164) for Odocoileus spp. Antibody-positive animals were identified throughout the state with no statistically significant differences among geographic regions. No statistically significant gender or age-related differences in antibody prevalence were demonstrated at either the genus or species level. This serosurvey indicates that exposure to DPV is common in Odocoileus populations in Oregon. Given the low rates of observed DPV-related disease, this high antibody prevalence suggests a pathogen of low virulence.
在美国俄勒冈州，对五种鹿类动物进行了血清中和试验，以检测其针对鹿痘病毒（DPV）的抗体。50头麋鹿（罗斯福马鹿和尼尔森马鹿）均未检测到可检测的抗体。其余物种中针对DPV的抗体流行率为：黑尾鹿（哥伦比亚白尾鹿）中为52%（n = 55），骡鹿（白尾鹿）中为32%（n = 59），哥伦比亚白尾鹿中为36%（n = 50），白尾鹿属的总体抗体流行率为40.2%（n = 164）。在全州范围内均发现了抗体呈阳性的动物，不同地理区域之间无统计学显著差异。在属或种水平上，均未显示出抗体流行率在性别或年龄方面存在统计学显著差异。这项血清学调查表明，俄勒冈州白尾鹿种群中普遍接触DPV。鉴于观察到的与DPV相关疾病的发生率较低，这种高抗体流行率表明该病原体的毒力较低。
