FIG. 5.
HCA showing the discrimination of the nine genomovars of BCC and two B. cenocepacia subtypes (subtypes IIIA and IIIB). The dendrogram was obtained by using the Ward algorithm, vector-normalized first-derivative spectra, and the information contained in spectral windows of 1,200 to 900, 1,450 to 1,350, 1,330 to 1,250, and 3.000 to 2,800 cm−1. HCA clearly discriminated among the nine species of BCC and two B. cenocepacia lineages (lineages IIIA and IIIB). Only reference strains were included in the analysis. Three replicate spectra from four independent experiments with each strain were used.
