Abstract
Infectious bovine rhinotracheitis (IBR) virus grown in bovine embryo kidney cell cultures was concentrated and purified in Ficoll density gradients. The polypeptide composition of the virus was studied by polyacrylamide gel electrophoresis. The mature virion contained 18 structural proteins with MW from 250,000-29,000 daltons; 8 of them were glycosylated. The similarity of IBR virus protein composition to proteins of other herpetoviruses [herpes simplex virus and pseudorabies virus] is discussed.
