Mice were inoculated with B. burgdorferi strains S9 (WT), S9/pBSV2*flaBp-bbd18 (WT+cBBD18), or S9/chase-pBSV2G (WT/chase).
Seroconversion to B. burgdorferi whole-cell lysates was assessed by immunoblotting 3 weeks after needle inoculation of 104 spirochetes.
Isolation of spirochetes from mouse tissues was attempted 5 weeks after inoculation.
P value of <0.0005 compared to WT and P value of <0.005 compared to WT/chase, using Fisher’s exact test.
