ABSTRACT
Bovine embryonic kidney cells were infected with bovine herpesvirus 1 (BHV1) or were sham-inoculated. When cytopathic effect was apparent, the cells were treated with beta-propiolactone, formalin, heat (56 degrees C), or ultraviolet irradiation until the virus was inactivated. Infected-treated, infected-untreated (IU) and sham-inoculated cultures were solubilized using Triton X-100 detergent. Resulting preparations were tested by 2-dimensional- and fused rocket-immunoelectrophoresis and were evaluated for their ability to inhibit virus neutralization by BHV1 antiserum. Eleven viral antigens were detected consistently in IU preparations, which strongly inhibited virus neutralization. Eight or more IU antigens were detected in beta-propiolactone-treated, formalin-treated and heat-treated preparations; these inhibited virus neutralization less strongly than the IU preparations. No IU antigens were detected in ultraviolet-treated preparations, nor did this material inhibit virus neutralization. One of the IU antigens was reduced preferentially by all treatments. The selective destruction of antigens by the various treatments might allow antigen-specific serological testing to distinguish vaccinated from naturally-exposed cattle.
