Table 2.

Increased frequencies of reactivation, MHV68-genome-positive cells, persistent infection, and reactivation efficiency in PECs from PML^−/− mice at 42 days postinfection

Mouse strain	Frequency of reactivation	Frequency of genome-positive cells	Reactivation efficiency (%)^b	Frequency of persistent infection
PML^−/−	1/29,849 (1/25,319, 1/34,380)^a	1/848 (1/619, 1/1,078)^a	2.84%	1/351,445 (1/238,334, 1/464,556)^a
PML^+/+	1/84,050 (1/68,665, 1/99,435)^a	1/1,316 (1/958, 1/1,673)^a	1.57%	1/2,827,263 (1/352,524, 1/5,302,002)^a
Fold increase	2.8 (P < 0.001)	1.55 (P = 0.03)	1.8	8 (P < 0.001)

Values in parentheses are upper and lower limits (95% confidence intervals).

Reactivation efficiency (%) = (frequency of reactivation/frequency of genome-positive cells) × 100.
