Figure 3.

Differences in MHC-II expression levels in tonsillar myeloid cells following CSFV Alfort-187 and C-strain infection. The mean fluorescence intensity (MFI) of MHC-II expression associated with each of the tonsillar myeloid cell populations was evaluated at each time point following virus inoculation. Graphs show the MFI for 4 pigs culled at each time point for Alfort-187 (red squares), C-strain (blue circles) and the 9 h timepoint for the mock infected control animals (black dotted line). Boxes represent the 25/75% percentile of data with the median and data values shown. Statistical differences between C-strain and Alfort-187 were evaluated by a two-way ANOVA with Bonferroni correction (* p < 0.05, **** p < 0.0001).
