Enhancement of antibody response to bovine herpesvirus 1 with non-specific immunostimulants.

: Stimulatory effects of aluminium hydroxide, lipopolysaccharide (LPS), muramyldipeptide (MDP), and empty liposomes on the antigenicity of inactivated bovine herpesvirus 1 were tested in mice. Compared with the standard effect of aluminium hydroxide, stronger antibody responses were observed in mice treated with empty liposomes or LPS alone, or a combination thereof. The strongest antibody response was recorded in mice treated with a combination of inactivated BHV-1, MDP and empty liposomes.
