Fig 4. Changes in B cell populations in animals infected with NiV.

The percent of B cells in the total population of analyzed cells is presented for individual animals in the low dose group (A and C) and the high dose group (B and D). Linear regression analyses (C and D) to determine the rate of change over the course of acute disease for all animals and convalescence for the animal that survived infection. The r-values for the linear regression analyses are provided in S1 Table. Linear regression analysis was performed on samples from all animals through day 12 (acute phase) with additional analysis of the surviving animal over the entire course of disease (blue dashed line).
