Each of the three dbpAB clones was inoculated into two SCID mice, and the parental clone 5A18NP1 was inoculated into five mice as a control. All animals were sacrificed 1 month after inoculation. Heart, tibiotarsal joint, and skin specimens were harvested and cultured for spirochetes in BSK-H complete medium.
