Bluetongue virus viral protein 7 stability in the presence of glycerol and sodium chloride.

Purpose: The Bluetongue virus (BTV) is an economically significant disease that affects mainly wild and domestic ruminants. BTV is most often seen symptomatically in sheep, but is easily carried by goats, cattle, and wild ruminants. To date there are several problems with the vaccines currently available for BTV, and one of the most promising candidates to increase vaccine efficacy is a protein-based vaccine, for which viral protein 7 (VP7) is a great candidate to be included in it.
