Identification of Francisella tularensis Cluster in Central and Western Europe
Figure 1. Genetic relationships between Francisella tularensis subsp. holarctica strains isolated in Switzerland and strains of wider geographic origin. The unweighted pair group method with arithmetic mean phylogram is based on the combined Ftind and multiple-locus variable-number tandem repeat analysis. Bootstrap values >80% are given at the respective nodes and were calculated by using 10,000 iterations. Scale bar indicates genetic distance.
