Persistent infections at day 270 in hamster liver and kidney by SV40 wild-type strains and microRNA mutants.

SV40, simian virus 40; Und, undetectable.aValues represent the average of normalized viral DNA copies/106 cells. The numbers of animals tested (6–9 each per virus and tissue) and those found to be virus-positive (0–8 each) are shown in Table 1.bThe following comparisons were statistically significant by the Wilcoxon rank-sum test at p≤0.05: SVCPC-SM2 vs. SVCPC-WT in both liver and kidney, SVCPC-SM2 vs. 776-SM1 in both liver and kidney, and 776-WT vs. 776-SM1 in liver.
