Virus secretion in co-infections of different West Nile virus (WNV) and Usutu virus (USUV) lineages. Co-infections were performed with WNV lineage 1 (Italy, 2009) and 2 (Germany, 2018) and with USUV Europe 3 (Germany, 2011) and Africa 3 (Germany, 2016) in vertebrate (Vero B4) as well as mosquito cell lines (C6/36). Co-infections were performed with a multiplicity of infection (MOI) of 1 for both viruses. The solid and dashed lines are drawn through the mean values of the three biological replicates for all tested time points measured by RT-qPCR based on a relative and absolute standard curve running in parallel. The error bars represent the standard deviation (± SD). Incomplete error bars occur when y-min of the error bars is negative and therefore not displayed in the logarithmic y-scale
