Molecular Detection of Persistent Francisella tularensis Subspecies holarctica in Natural Waters

Figure 4

Phylogenetic analysis based on Francisella 16S rRNA sequences obtained from water samples in Örebro (Water A/B, this study), environmental soil samples [6] and reference sequences from GenBank. The samples are named according to the sampling points, Örebro A and B (Figure 1). Analysis was performed using maximum parsimony.
