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
