Mice were given daily intraperitoneal injections of 200 μg of control IgG or RB6 beginning on day −1. Mice were infected with 2.5 × 105 B. burgdorferi cells on day 0 and blood was collected from the retroorbital plexus weekly. Blood smears were stained with Diff-Quick, and at least 200 cells per slide were counted. On days 0 and 14 one mouse per treatment per mouse strain was randomly chosen for bleeding. On days 7 and 21 groups of three mice were bled, and the data are averages ± standard deviations. The data are representative of at least four separate experiments.
