Figure 1

Multiple alignment of the 11 Francisella lpnA sequences obtained from mosquitoes in Sweden (hatched from field-collected larvae) with previously published sequences of Francisella species and subspecies, and Francisella-like endosymbionts (FLE). Boxed nucleotides represent target sequences of lpnA primers. The nucleotide positions 592–674 refer to F. tularensis holarctica live vaccine strain (LVS). Colors indicate individual nucleotides to clearly delineate those diverging from the F. tularensis
