a
Prevalence of Borrelia infections in adult and nymphal I. ricinus ticks in a woodland grazed by cattle and a comparable ungrazed woodland. Where applicable, absolute numbers are given in parentheses.
b
Five coinfections were found in nymphs collected in the ungrazed oak forest (two coinfections of B. garinii with B. valaisiana, one of B. garinii with B. burgdorferi sensu stricto, one of B. garinii with B. afzelii, and one of B. afzelii with B. valaisiana).
c
Borrelia sp. sensu lato, genotype could not be determined.
