The antiviral activity of oral drops and dry extract was measured with plaque-reduction assays (Cooper 1955) in plaque forming units (PFU) for FluA and pFluA, Para 3, RSV, HRV 14, CA9 or with the analyses of a cytopathogenic effect (CPE) for Adeno 5.

Determination of virus-induced cytopathogenic effects and virus titres revealed that EPs [R] 7630 at concentrations up to 100 [micro]g/ml interfered with replication of seasonal influenza A virus strains (H1N1, H3N2), respiratory syncytial virus, human coronavirus, parainfluenza virus, and coxsackie virus but did not affect replication of highly pathogenic avian influenza A virus (H5N1), adenovirus, or rhinovirus.

during the growth or the stationary phase) different cytopathogenic effects
might be observed.
To measure the inhibitory effect on the viral cytopathogenic effects
(CPE) in cell culture, nebrodeolysin was exposed to different cell cultures that were infected by a variety of DNA and RNA viruses.
