The virus inhibitory activity and selectivity of certain benzimidazole, benzotriazole, and naphthimidazole derivatives were determined with influenza B and polio type 2 viruses. Among the sixty-five compounds examined, several were highly active inhibitors of influenza B virus multiplication in the chorioallantoic membrane in vitro. The following compounds, listed in order of increasing inhibit...

Upon the basis of limited data available ten years ago, a concept of viral infection became popular in which the cell was redirected after infection to the exclusive production of virus. These original data (Cohen, 1949) that concerned the quantitative accounting of the nucleoproteins during the infectious sequence, offered a direct line of investigation into the mechanism of this redirection a...

Here we describe for the first time the productive in vitro infection of human retinal pigment epithelial cells by varicella-zoster virus (VZV), resulting in a typical cytopathic effect (CPE) that is characterized by enlarged cells with increased granularity. Depending on the CPE dissemination, high titers of up to 1.6 x 10(6) PFU of cell-free and cryostable VZV/ml can be recovered.
