FIG. 7.
Reactivation of quiescent in1382. Monolayers of 8 × 105 HFFF2 cells were infected with 3 × 106 PFU of in1382 and maintained at 38.5°C for 10 days. Monolayers were trypsinized and replated at 50% of the original density and infected with 3 × 106 PFU of in1324 (a to g) or in1372 (h). Cells were stained at days 1 (a), 2 (b), 3 (c), 4 (d), 6 (e, h), 8 (f), or 10 (g) after infection with in1324 or in1372.
