Figure 4. Cladograms depicting relationships among Francisella tularensis strains obtained by maximum parsimony and bootstrap analysis that used indel, multilocus variable-number tandem repeat analysis (MLVA), or combined data. Nodes supported by <50% of bootstrap pseudoreplicates were collapsed. A) Cladogram obtained solely from the use of MLVA data. B) Cladogram from the use of indel data. C) Cladogram from the combined use of indel and MLVA data. The dual bootstrap support values presented represent the use of each of 2 alleles, found at locus Ftind-32 of strain ATCC 6223.
