SUMMARY A total of 14 isolations of Akabane virus were made from the blood of five cattle during sub‐clinical infection. The serial isolation of this virus from four of these animals suggests a viraemia of at least 3 or 4 days. Neutralising antibody to Akabane virus in the serum of infected calves reached an initial peak titre of 32 to 256 four to five days after the viraemia but later rose further to a range of 64 to 512. Three isolations of Akabane virus were made from Culicoides brevitarsis collected nearby in the same period. C. brevitarsis was the dominant haematophagous midge present during that time. These findings strengthen the case for C. brevitarsis to be considered as a vector of Akabane virus.
