From: Differential neurovirulence of Usutu virus lineages in mice and neuronal cells
EU2 USUV strain is more virulent and persistent longer in different brain cells. Murine neuronal (a), human pericyte (b), and human endothelial (c) cells cultures were infected with USUV at a MOI of 0.1. Bright light images of CT- and USUV-infected neuron at 4 dpi (a) and endothelial cells at 6 dpi (c) show atypical CPE in EU2 condition while infection induces no CPE in pericytes at 4 dpi (b). Viral quantification for each cell type is expressed in TCID50/mL. Results are expressed as mean ± SEM of 3 independent experiments. *p < 0.05, **p < 0.01, and ***p < 0.001
