Laboratories where diagnostic tests were performed included:
National Veterinary Institute (SVA), Uppsala
1) Biorad TeSeE Elisa rapid test; - Western blot; - immunostained sections; 3 Feb 2006; positive.
OIE Reference Laboratory, Veterinary Laboratories Agency (VLA), Weybridge, United Kingdom
2) OIE Western blot; - VLA hybrid Western blot; - review of SVA immunostained sections; 3 Mar 2006; positive

The myostatin gene and its relevance to livestock animals
Myostatin, also known as growth differentiation factor 8, a member of the transforming growth factor‐beta super‐family, is a negative regulator of muscle development. Myostatin acts at key points during pre‐ and post‐natal life of amniotes that ultimately determine the overall muscle mass of an animal. A fascinating summary about the current an overview of mechanisms of action and its potential relevance in livestock animals.
