This study compares the characteristics of naturally occurring antiviral activities in nonhuman mammalian sera to UTIβ (University of Texas virus inhibitor β), an innate, non-specific viral inhibitor found in human serum. The antiviral agent in sera from four different species appears to possess properties similar to those of UTIβ, e.g. molecular weight of 60 ± 10 kDa, broad spectrum antiviral activity, glycoprotein structure with antiviral oligosaccharide moiety(s) attached to a carrier protein, and inhibition of most viruses by preventing their attachment to target cells. These findings suggest that UTIβ or UTIβ-like virus inhibitors are a normal component of the non-specific immune defenses of mammals.
