Increased size and frequency of omental immune aggregates in MHV68-infected mice.

Omenta from mice inoculated intraperitoneally (i.p.) with 1000 plaque forming units (pfu) virus in complete media (cDMEM) or cDMEM alone (mock) and harvested at the indicated times post infection. Omenta were cryosectioned and stained using DAPI-containing mounting media. Dense DAPI-staining in immune aggregates, “milky spots,” is outlined by dashed ovals.
