The effects of MCMV infection on CFU-S. The mice were inoculated with 1 × 105 PFU of MCMV. Bone marrow cells were obtained on day 1, 3, 5, and 7 pi and then the graded numbers of bone marrow cells were transferred intravenously into lethally irradiated mice. On day 14 after transfer, the recipient mice were killed in order to remove their spleens. Surface colonies of the spleens were counted to determine the total number of day-14 CFU-S in the donor bone marrow. The results of four mice for each group are expressed as the mean ± SEM. *Significant decrease versus uninfected control (P < .01).
