TABLE 1.

Viral yields from infections with different viral strainsa

VirusTiter, 24 hpi (PFU/ml)
wt HSV-14.4 × 107
dUL311.5 × 105
dUL31R2.2 × 106
dUL344.5 × 103
dUL34R9.6 × 105
  • a Viral yields were measured following infection of HEp-2 cells with wt HSV-1, the viral mutant dUL31 or dUL34, or the rescued virus dUL31R or dUL34R. At 24 hpi, total infectivity was measured by plaque assay on Vero cells.
