Abstract
The direct immunoperoxidase test has been used to detect rinderpest virus antigens in infected bovine kidney cell cultures to study the multiplication of the virus. Infected bovine kidney coverslip cultures were sequentially tested with peroxidase-labelled, anti-rinderpest globulins at 3, 6, 24, 48, 72, 96, 120 and 144 h post-infection. The progressive virus-specific cytopathic changes compared well with the increase in the number of cells showing the presence of viral antigens when tested by the direct immunoperoxidase test. The specificity of the reaction was confirmed by using negative and antiserum-blocked BK cell cultures on coverslips.
