B. burgdorferi clearance in untreated, CLL-treated or splenectomized wild-type mice and in Cd1d^−/− mice at 3 d after B. burgdorferi infection, assessed by quantitative PCR analysis of B. burgdorferi flaB (pooled DNA samples).

^*P < 0.05,

^**P < 0.01 and

^***P < 0.001, versus wild-type (Bonferroni’s mutiple-comparison test).

Data represent one experiment with three to five mice, depending on experimental group (mean and s.e.m. of two independent measurements).
