The incidence of Lyme borreliosis (LB) in a region may reflect the prevalence of  Borrelia  in the tick population. Our aim was to investigate if regions with different LB incidences can be distinguished by studying the prevalence and diversity of  Borrelia  species in their respective tick populations. The  Borrelia  load in a feeding tick increases with the duration of feeding, which may facilitate a transmission of  Borrelia  Spirochetes from tick to host. Therefore, we also wanted to investigate how the  Borrelia  load in ticks that have fed on humans varies with the duration of tick feeding. During 2008 and 2009, ticks that had bitten humans were collected from four regions of Sweden and Finland, regions with expected differences in LB incidence. The duration of tick feeding was estimated and  Borrelia  were detected and quantified by a quantitative PCR assay followed by species determination. Out of the 2,154  Ixodes ricinus  ticks analyzed, 26% were infected with  Borrelia  and seven species were identified.  B. spielmanii  was detected for the first time in the regions. The tick populations collected from the four regions exhibited only minor differences in both prevalence and diversity of  Borrelia  species, indicating that these variables alone cannot explain the regions’ different LB incidences. The number of  Borrelia  cells in the infected ticks ranged from fewer than ten to more than a million. We also found a lower number of  Borrelia  cells in adult female ticks that had fed for more than 36 hours, compared to the number of  Borrelia  cells found in adult female ticks that had fed for less than 36 hours.
