Figure legends
Figure 1 Morphological appearrence of four calves exposed to
Schmallenberg virus during fetal development. All calves have
generalized arthrogryposis affecting both the limbs and the spine, but
the morphological expression of the condition varies among cases
Figure 2 Brain lesions in calves exposed to Schmallenberg virus
during fetal development. (a) Hydrocephalus (asterisk) and dilation of
the mesencephalic duct (arrow), case 3. (b) The forebrain developed
bilateral collapse (circles) upon removal of the brain from the cranial
vault due to decreased intraventricular pressure, case 1 (c) Severe
hydrocephalus (asterisk) and ventral opening of the mesencephalic duct
(arrow), case 1. (a-c): bar = 2 cm
Figure 3 Map of Denmark indicating the location of herds, where
a malformed Schmallenberg virus exposed calf was born in April – May
2021. Cases positive for viral RNA by real-time RT-PCR are shown in red,
while cases positive for fetal antibodies against Schmallenberg virus
are shown in green. A case being negative for viral RNA and doubtful for
fetal antibodies is shown in yellow
