Equine viral arteritis. Current status in Finland.
A serological study for antibodies against equine arteritis virus (EAV) in Finland was performed during 1996. All equine sera delivered to the Virology Unit at the National Veterinary and Food Research Institute were tested with a micro-neutralization test, using the Arvac strain as antigen. The study also included imported horses to evaluate EAV circulation in the countries of origin. Nucleocapsid gene sequences of 2 Finnish equine semen isolates were amplified with RT-PCR and sequenced. The genetic relationships of those isolates with strains isolated elsewhere in the world were analyzed. The Finnish isolates shared 98.2% nucleotide identity, and the closest relatives to the Finnish strains were isolated from the semen of 2 Norwegian horses in 1988 and 1989.
