Figure 2.

Inflammatory potential of eight B. burgdorferi OspC genotypes in macrophage cultures. The 28 B. burgdorferi isolates used in experiments in Figure 1 were subdivided according to their OspC type. The box represents 25^th to 75^th percentiles; lines outside the box, 5^th to 95^th percentiles; and horizontal line in the box, median. For the comparison of OspC type A with type K or I, *P ≤ 0.05, **P ≤ 0.01, and ***P ≤ 0.001. There were no significant differences between OspC type K and OspC type I strains.
