Fig. 6.

(A) Mortality of the SCID mice infected with MCMV, followed by oral inoculation of Salmonella SL201 (1 × 10⁸ cfu/animal) carrying the empty vector pU6 alone (SL201) and the vector carrying different EGS expression cassettes (mPR1, mPR2, and TK112). We intraperitoneally infected CB17 SCID mice (five animals per group) with 1 × 10⁴ pfu MCMV, 36 h before Salmonella inoculation and repeated Salmonella inoculation every 5 d. (B and C) Growth of MCMV in the spleens (B) and livers (C) of the infected SCID mice. The viral titers represent the average obtained from triplicate experiments. Error bars indicate the SD.
