Figure 1.
(a) Specific distribution of Bifidobacterium (bifidum) in tumor tissues following a single i.v. injection of 5 × 106 c.f.u./mouse into Ehlich solid tumor-bearing mice. Each point represents the mean c.f.u./g tissue (n = 8). This figure was adopted from a previous study [12]. (b) Recombinant Bifidobacterium (longum) (6.9 × 108 c.f.u./mouse) was injected i.v. on day 1. Bacterial cells in each tissue were counted on day 2, 3, 4, and 7 by plating assays. * Mean c.f.u./g tissue (n = 5). This figure was adopted from Farumashia,15, (5), 438–440 (in Japanese).
