background the rate of mother-to-infant hepatitis c virus (hcv) transmission is relatively low, however, this mode of infection is the most important route for childhood hcv involvement. the chances of transmission are increased by the level of maternal hcv viraemia and maternal human immunodeficiency virus (hiv) co infection. objectives the objective of the present study was to determine the p...

Feline sarcoma virus (FeSV) rescued from transformed nonproducer mink or rat cells contains two FeSV-specific antigens (p15 and p12), and the feline oncornavirus-associated cell membrane antigen (FOCMA). All three antigens are helper virus-independent and are encoded by the FeSV genome. FOCMA, pl5, and p12 antigens cochromatograph as phosphorylated molecules of 85,000 molecular weight (pp85), a...

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 an...
