Abstract
Infectious Schmallenberg virus from bovine semen, Germany.
Highlights
We investigated the infectivity of Schmallenberg virus (SBV) RNA–positive semen by experimental subcutaneous injection of cattle and interferon α/β receptor–deficient (IFNAR-/-) mice [3]
The 2 infectious semen batches contained moderate (Cq 26.4) or low (Cq 34.2) viral loads of SBV RNA, indicating that a high sensitivity is required for reliable SBV RNA detection in semen samples [1]
The onset of SBV infection in the 3 animals injected with single semen straws ranged from 3 to 5 dpi, and not every straw was infectious, biologic and technical replicates of straws from 1 semen batch showed similar PCR results [1]
