چکیده

The objective of this study was to determine the protein
pattern and antigenic structure of BHV-1. Ten viral isolates
from cows with clinical signs of respiratory infections were
selected for this study and confirmed by SN test. All
samples were cultured on cell cultures and purified by
ultracentrifugation. Purified isolates were electerophorsed
using SDS-PAGE method and immunoblotted. Viral
antigens were detected using anti BHV-1 bovine antiserum
and molecular weight of the bands were determined. All
samples showed identical band number and molecular
weight except for one sample which revealed an additional
120-125 KDa band. Also immunoblotting data resulted in
identified of twelve bands (150, 130, 115, 97, 77, 70, 55,
45, 40, 38, 32 and 25 KDa) suggesting involvement of
these antigens in evoking humoral immune response in
affected cattle.
