Hemagglutination-inhibition (HI) tests of serum samples from 51 bighorn sheep (Ovis canadensis) and 4 bighorn-domestic hybrid sheep from Wyoming and Montana revealed bovine myxovirus parainfluenza-3 antibody titers of 1:20 or greater in 6 animals. The serums of two bighorns with pneumonia were negative for neutralizing antibodies against IBR virus and the serums of 9 animals failed to show significant titers against 2 strains of human Asian influenza virus. Tissue cultures of nasal swabs and lung tissue were negative for cytopathogenic effects and hemadsorption.
