Preferential persistence of SV40 in kidney compared to liver and spleen.

SV40, simian virus 40.
aValues represent the ratio of the average observed (nonadjusted) results from day 45 and day 3 for each virus in the indicated tissues. The numbers of tissues from different animals tested per virus at each time point (usually n = 4) are listed (Table 1). Note the higher level of persistence of each virus in the kidney as compared to liver and spleen.
