FIG 4.
Detection of mCMV titers in naive mCMV-infected and FV/mCMV-superinfected mice. Naive C57BL/6 mice were infected with FV; control mice received PBS. In the chronic phase, 6 weeks after FV infection, mice were superinfected with mCMV. mCMV titers were determined in the spleens and livers at day 7 after mCMV infection. Data were pooled from 3 to 4 independent experiments. Dashed lines display the detection limits.
