Figure 1. TLR4 is required to prevent transmission of B. bronchiseptica between mice.

Figure 1

The number of CFU of B. bronchiseptica recovered from the nasal cavity of HeJ, HeN, C57BL/6 , μMT, TCR−/−, or Rag−/− secondary mice dissected after three weeks of exposure to an index case. Index cases were of the same genotype as secondary mice. Individual secondary mice are represented by dots. Box spans the interquartile range, and the median value is represented by a bar. The whiskers span the 1st and 4th quartile. The limit of detection is marked by a dashed line. The proportion of infected mice in each group is listed above the box and whisker plot. Figure represents the cumulative results of 2–3 independent experiments for each mouse genotype.
