Research dispels post-infection immunity myth
The study, by Dr Ian Nanjiani of Westpoint Veterinary Group in Sussex, included 10 sheep flocks in the north, midlands and south of England. The flocks had either confirmed outbreaks of Schmallenberg during the past two years or were located adjacent to flocks where Schmallenberg was confirmed or, in the case of two flocks in Cumbria, had no known exposure to the virus.
A random sample of 60 breeding females was blood tested in each flock to assess susceptibility to and resistance to Schmallenberg.
