In the cells collected after 48 h digestion, we observed a slightly but not statistically significant higher infection in the Lena-inoculated cells (4.2 ± 2.0%) than with LV-inoculated cells (1.5 ± 0.7%) (p = 0.073) and more than 90.4% of the infected cells were CD163+ (Figure 7B left and Additional file 3A). Here, CD163 is linked to infection.
