Figure 5. Colony size was dependent on distance to vessels.

Figure 5

A, B) Relationship between colony size and distance for (A) control and (B) trg− Salmonella. Colonies were segregated into three groups: (a) colonies greater than 60 µm from the nearest vessel (vertical line); (b) colonies containing more than 20 bacteria (horizontal line); and (c) colonies containing less than 20 bacteria and closer than 60 µm to the nearest vessel. No colonies with more than 20 bacteria were farther than 60 µm from vessels. C) Percentage of colonies in the three categories: (a) penetrating (>60 µm), (b) proliferating (>20 bacteria), and (c) inactive (<60 µm and <20 bacteria). D) Percentage of bacteria in the three categories.
