Figure. . Phylogenetic analysis of the recA gene from the Burkholderia cepacia complex. The phylogenetic diversity of the B. cepacia complex observed after nucleotide sequence analysis of the recA gene is shown. Isolates recovered from Canadian CF patients that are representative of strains of currently indeterminate genomovar status (Table 2) appear in bold and lack species identification; all fall within the current B. cepacia complex. The tree was drawn as described (16). The recA sequence from Bordetella pertussis was used as a root, and the genetic distance is indicated by the bar.
