Study on Correlation of Maedi-Visna Virus (MVV) with Ovine Subclinical Mastitis in Iran.

ABSTRACT: Maedi-Visna is an important slow viral disease of sheep leading to progressive pneumonia, encephalitis and mastitis. Udder is one of the organs affected by MVV. Despite the fact that in Iran Maedi-Visna is known since 2000, to the authors' knowledge correlation of subclinical mastitis and infection with MVV has not been assayed.
