  1. Infection prevalence of three Borrelia spirochetes in ticks removed from birds and rabbits and rabbit ear biopsies collected in Michigan, 2004–2008. Sample sizes and infection prevalence are presented as both the sum across each sample type and specific to each tick species and life stage. The B. burgdorferi infection prevalences are taken from Hamer et al.[36]. Reported infection prevalences are considered a minimum due to a small number of additional samples with PCR bands indicative of a Borrelia species for which sequences were not obtained.
