WebFeb 15, 2024 · In this assay, fluorescence of Vero E6-eGFP cells (provided by Dr. K. Andries J&JPRD; Beerse, Belgium) declines after infection with SARS-CoV-2 due to virus-induced cytopathogenic effect. In the presence of an antiviral compound, the cytopathogenicity is inhibited and the fluorescent signal maintained. WebOct 12, 2024 · Presumptive identification of virus types can be made by observing morphological changes produced in host cells (CPE), caused by cytopathogenic viruses. Common damage to the host cells includes rounding of cells, a change in texture (granular or hyaline—glassy), and formation of a syncytium (fusion of infected cells).
