TABLE 2 .

Constitutive expression of bbd18 prevents B. burgdorferi infection of mice by tick transmission

Strain^a	No. of infected mice/no. of mice fed on by infected larvae^b	No. of infected mice/no. of mice fed on by infected nymphs^b
WT	2/2	5/5
WT+cBBD18	0/6^c	0/7^c

^{^a}

Mice were fed upon by ticks infected with B. burgdorferi strains S9 (WT) or S9/pBSV2*flaBp-bbd18 (WT+cBBD18).

^{^b}

Mouse infection determined by seroconversion to B. burgdorferi whole-cell lysates and isolation of spirochetes from mouse tissues 3 weeks after tick feeding.

^{^c}

P value of <0.05 compared to WT using Fisher’s exact test.
