Transmission feeding experiments with Ornithodoros hermsi ticks infected with the transgenic Borrelia hermsii Δvtp::ospC+ producing OspC.

Weeks PI^a	Single Mouse Fed Upon by ticks	Total Ticks Fed	Stage^b	Mouse Infected^c
15	Mouse 1	12	1N, 7♂, 4♀	+
15	Mouse 2	18	2 N, 5♂, 11♀	+
15	Mouse 3	13	5 N, 1♂, 7♀	+
15	Mouse 4	20	2 N, 7♂, 11♀	+
26	Mouse 5	23	3 N, 5♂, 15♀	+
26	Mouse 6	20	1 N, 8♂, 11♀	+
26	Mouse 7	19	3 N, 2♂, 14♀	−
26	Mouse 8	22	2 N, 14♂, 6♀	+

PI = post infection, time since ticks acquired spirochetes from infected mouse

N = nymph, ♂ = male, ♀ = female (numbers of each in the pool of ticks that fed)

+ = mouse became spirochetemic and seroconverted; − = mouse had no detectable spirochetemia and did not seroconvert
