Plaque-reduction assay (PFU), cytopathogenic effect (CPE), immunoassay (ELISA): The antiviral activity of Bioaron C[R] was measured with plaque-reduction assays (Cooper 1955) in plaque forming units (PFU) for FluA (H1N1, H3N2), FluB (Yamagatal, Beiying) and Para 3, RSV, HRV 14, CA9 or with analyses of a cytopathogenic effect (CPE) for Adeno 5.

After occurrence of a cytopathogenic effect in a culture, the supernatant was harvested and stored at -20[degrees]C for DNA extraction.
The analyses of the plaques (plaque forming unit = PFU) and the cytopathogenic effect (CPE) were performed 3-7 days later.
The neutralizing titer was calculated on the basis of the number of wells showing cytopathogenic effect by using the Spearman-Karber method and reported as the reciprocal titers of serum dilutions that exhibited 50% neutralization.
Because no antigen detection in cells was attempted, the cytopathogenic effect could have been caused by any other virus blindly isolated.
A positive result was defined as a serum sample that showed a lack of cytopathogenic effect at a dilution of 1:160 (9).
Flasks were incubated at 37[degrees]C and observed daily for evidence of cytopathogenic effect (CPE).
Characteristic VZV cytopathogenic effect was seen after 9 days in cell culture.
Poliovirus/PVSRIPO causes drastic, rapid cytopathogenic effects leading to gross morphologic changes and cell detachment.
Viruses from the culture supernatants of 293A cells that showed cytopathogenic effects were purified by cesium chloride banding.
The influenza H1N1 was found to induce severe cytopathogenic effects in a dose-dependant manner, however the cells treated with RGE displayed decreased viral cytopathogenic effects and reduced cell death caused by the virus.
