Figure 4. The change over time in colonization and bacterial load in rats inoculated intradermally with ∼20 WT Y. pestis (white circles) or Δypmt1.66c (black circles).

Figure 4

N.D: not determined. Each circle represents one animal. The times to colonization were significantly longer in rats infected with the mutant than in rats infected with the WT strain (p<0.05). P values were determined using 2-way analysis of variance.
