Frequency of genome-positive GC B cellsa

aData were obtained from pools of at least five spleens.bFrequencies were calculated by limiting-dilution analysis with 95% confidence intervals (CI).cThe percentage of GC B cells from total spleen was estimated by FACS analysis.dThe total number of cells was estimated from the percentage of the total spleen, based on an estimate of 2×108 cells/spleen.eThe number of latently infected cells was based on the frequency of latency within GB B cells and the estimated total number of cells.
