Panel A: Apparent prevalence of brucellosis in Eurasian wild boar (
) in Bio-regions 1 to 5. Dots are proportional to prevalence. Only data from localities with at least 10 wild boar samples are shown. Panel B: Distribution of the different haplotypes of Brucella suis strains isolated from wild boar. Points represent an infected population cluster rather than individual isolates; the dotted line represents the south-western distribution limit of the European brown hare (Lepus europaeus). Panel C: Characteristics of the B. suis biovar 2 haplotypes isolated when identified by PCR (Mpx-PCR) and further analysis of omp2a, omp2b and omp31 genes by PCR-RFLP.
