Bluetongue Carrier Midge Appears to Prefer Cattle
UK - Updating the situation regarding bluetongue, Roger Daniels, from the Veterinary Laboratories Agency in Carmarthen, said there was some indication – though not to be taken for certain – that there was less likelihood of finding the virus-carrying Culicoides midges in mountainous and hill areas.The incubation period was six to nine days, with the clinical signs in sheep being a fever with a temperature of up to 42 degs C, conjunctivitis, dribbling saliva, lameness and abortion.
Some cases, however, could have difficult to detect sub-clinical symptoms.
The signs in cattle were very much similar to sheep, with dairy cows producing less milk and the presence of teat lesions.
