Schmallenberg virus infection
|Author(s) :||K. Wernike, A. Elbers & M. Beer|
Since Schmallenberg virus, an orthobunyavirus of the Simbu serogroup, was identified near the German–Dutch border for the first time in late 2011 it has spread extremely quickly and caused a large epidemic in European livestock. The virus, which is transmitted by Culicoides biting midges, infects domestic and wild ruminants. Adult animals show only mild clinical symptoms or none at all, whereas an infection during a critical period of gestation can lead to abortion, stillbirth or the birth of severely malformed offspring. The impact of the disease is usually greater in sheep than in cattle. Vaccination could be an important aspect of disease control.
