Figure 2

Figure 2. Genetic relationships among 35 North American Francisella tularensis subsp. tularensis A.II. subpopulation isolates based upon allelic differences at 24 variable number tandem repeat (VNTR) markers. County, state, and year of isolation are specified to the right of each branch or clade. G indicates number of distinct VNTR marker genotypes, triangle indicates epidemiologically linked isolate, asterisk indicates isolate with an unknown year of isolation, boxed designation indicates F. tularensis type strain B-38, and square indicates a set of genetically identical but epidemiologically unlinked isolates.
