RESUMO
This study was done after identifying animals with a twisted carpal joint in goat herd. These included a kid goat walking on its articulus carpii and a newborn goat with a stiff leg. Necropsies of the diseased goats revealed swollen carpal joints that were twisted backwards. Arthritis was observed during microscopic examination of the carpal joints. Very low levels of eosinophil, leucocyte, and lymphocyte cell infiltration were found in the central nervous system and meninges. Serum copper levels were significantly decreased in most of the animals. All of these results led us to diagnose the animals with swayback disease.

In October 1977 clinical bluetongue broke out in Aydin province, western Turkey and spread to adjacent provinces in the autumn months of 1978 and 1979. The outbreak was caused by a virus of serotype 4 and appeared to occur in a totally susceptible population. It was eventually controlled by widespread use of attenuated type-specific vaccine. Bluetongue virus was isolated from sheep on several occasions and also from a calf with congenital arthrogryposis and hydranencephaly. This latter finding is discussed in relation to Akabane virus, a recognised arbovirus teratogen thought to be present in the same area at the same time.
