A viral yield reduction assay is used to evaluate the effectiveness of antiviral agents, drugs, or experimental treatments in reducing the total production of virus particles by infected host cells. This assay is essential in virology and drug development for assessing the impact of potential treatments on viral replication and productivity

Products tested against Influenza A/Puerto Rico/8/34 in a yield assay in MDCK cells

Test articles (TAs)1-4 are products tested in a yield reduction assay against IFV-A/PR/8/34 in MDCK cells. Among all tested compounds, the largest degree of % inhibition was observed in cells treated with TA3. Conversely, the lowest antiviral efficacy against IFV-A/PR8 is observed in cells treated with TA2.

Compounds tested against Dengue 2, strain New Guinea C in a yield reduction assay

Test articles (TAs) 1-4 are compounds that were tested for antiviral efficacy against DENV-2 NGC in a yield reduction assay in Vero cells. The compounds were incubated with the cells for a predetermined amount of time with a known amount of DENV-2 NGC. Supernatants were collected and the amount of virus in each sample was quantified via plaque assay. % inhibition was calculated by comparing the reduction of viral titer when compared to the virus only control.

The yield reduction assay is based on the principle that antiviral agents, when effective, reduce the overall yield of virus particles produced by infected cells. By measuring the reduction in viral production in the presence of these agents, researchers can assess their antiviral efficacy.

Yield reduction assays are crucial methodologies for assessing the antiviral efficacy of drugs and treatments, contributing significantly to the development of antiviral therapies and the understanding of viral diseases. They provide important insights into the impact of various treatments on viral replication and productivity.
