VNP20009 preferably accumulated in tumors in vivo. a The representative images of LB agar plates planted with different homogenized tissue after serial dilution or blood on days 2 after injection. The dilution factor was marked, 1/10 for ten fold dilution. b The quantitative analyses of the bacterium count by cfu/g tissue were presented for days 2, 7 and 14 post injections. Data shown was mean ± SD obtained from three independent experiments. * P < 0.01 vs the tumor group on days 2, ΔP < 0.01 vs the tumor group on days 7, #P < 0.01 vs the tumor group on days 14
