EBV copy number in PBMCs of tree shrews post-infection. In the 8 EBV-infected tree shrews, EBV copy number increased intermittently or transiently (a, b).The data for Ts5 and Ts6 are shown as representative of EBV-infection-negative tree shrews (c). The EBV copy number did not increase during the observation period in Ts5, Ts6 or Ts11-Ts13 (data not shown)
