All ewes were scrapie-positive based on brain examination (vacuolar changes and presence of PrPd/PrPres). The age is displayed in months (m) and days (d), with months displayed in calendar months; the somatic cell count is displayed in 103 cells/ml; milk volume is displayed in litres (rounded down).
* Staphylococcus epidermidis isolated.
** No bacteria isolated.
