Abstract

Schmallenberg virus (SBV) and bluetongue virus (BTV) are both transmitted by Culicoides biting midges and infect predominantly ruminants. To investigate the extent of virus spread in the 2022 and 2023 vector seasons, we serologically tested wild ruminants from western Germany. While antibodies against BTV were not detected in any animal, regardless of age or sampling time, numerous wild ruminants tested positive for antibodies to SBV. In 2022, a low seroprevalence of 4.92% was measured. In sharp contrast, 40.15% of the animals tested positive in 2023. Of the young animals, about 31.82% were seropositive, clearly indicating large-scale SBV circulation in summer and autumn 2023.

摘要

舍姆梁贝病毒（SBV）和蓝舌病病毒（BTV）均由致倦库蚊传播，主要感染反刍动物。为了调查这两种病毒在 2022 年和 2023 年媒介季节的传播范围，我们对来自德国西部的野生反刍动物进行了血清学检测。无论动物的年龄或采样时间如何，均未检测到针对 BTV 的抗体，但许多野生反刍动物对 SBV 的抗体检测呈阳性。2022 年，血清阳性率为 4.92%。相比之下，2023 年有 40.15%的动物检测呈阳性。在幼畜中，约 31.82%呈血清阳性，这清楚地表明 2023 年夏秋季 SBV 大规模传播。
