FIG 1.

The level of maternally transmitted B. afzelii-specific IgG antibodies was significantly higher in the MatAb⁺ offspring (n = 20) than in the MatAb⁻ offspring (n = 22) at 34 days postbirth (PB). The MatAb⁻ and the MatAb⁺ offspring are the offspring of 7 uninfected control mothers and 6 B. afzelii-infected mothers, respectively. The level of the maternally transmitted B. afzelii-specific IgG antibody response was measured in the blood of the offspring at 34 days PB using a commercial Lyme borreliosis ELISA. Shown are the medians (black lines), the 25th and 75th percentiles (edges of the box), and the minimum and maximum values (whiskers).
