Abstract

From 1981 to 1989, sera were collected from 3,077 white-tailed deer (Odocoileus virginianus) in Georgia and from 1,749 deer from 12 additional states in the southeastern United States. In Georgia, prevalence of precipitating antibodies to epizootic hemorrhagic disease virus (EHDV) and bluetongue virus (BTV), as determined by agar gel immunodiffusion tests, was dependent on physiographic region, age, and year. Overall prevalence of antibodies to EHDV and/or BTV was 11, 33, 48, and 14% for the Mountain, Piedmont, Coastal Plain, and Barrier Island regions, respectively. Results suggested varying patterns of EHDV and BTV activity throughout the state. Serologic results from other southeastern states were consistent with the Georgia sample; prevalence estimates (EHDV and/or BTV) for corresponding physiographic regions deviated by less than 10%. Over this larger geographical area, antibody prevalence in deer appeared to increase with decreasing latitude.

摘要

1981年至1989年期间，从佐治亚州的3077只白尾鹿（弗吉尼亚鹿）以及美国东南部其他12个州的1749只鹿身上采集了血清。在佐治亚州，通过琼脂凝胶免疫扩散试验测定，针对流行性出血病病毒（EHDV）和蓝舌病病毒（BTV）的沉淀抗体流行率取决于自然地理区域、年龄和年份。山区、皮埃蒙特、沿海平原和屏障岛地区针对EHDV和/或BTV的抗体总体流行率分别为11%、33%、48%和14%。结果表明该州各地EHDV和BTV的活动模式各不相同。其他东南部州的血清学结果与佐治亚州的样本一致；相应自然地理区域的流行率估计值（EHDV和/或BTV）偏差小于10%。在这个更大的地理区域内，鹿的抗体流行率似乎随着纬度降低而增加。
