marginal significanceP = 0.063
There were significant differences in the levels of the virus RNA between titrated virus at 10 -1 TCID 50 and at 10 -2 TCID 50 ( P = 0.001), between titrated virus at 10 -3 TCID 50 and at 10 -4 TCID 50 ( P = 0.046), between titrated virus at 10 -4 TCID 50 and at 10 -5 TCID 50 ( P = 0.014) except those between titrated virus at 10 -2 TCID 50 and at 10 -3 TCID 50 which showed a marginal significance ( P = 0.063).
