Figure 3: MCMV isolation from lung tissue of infected mice (unstained, ×100). MEF cells were incubated with suspension of lung tissue homogenates. (a) No CPE was present in MEF cells incubated with lung tissue homogenate from a mouse in Group E (uninfected control). (b) CPEs were observed in MEF cells incubated with lung samples from a mouse in group D.
