FIG. 2.

Dendrogram based on rpoB gene sequence comparison obtained with the neighbor-joining algorithm showing the phylogenetic relationship between animal strains of C. xerosis and the close relatives C. freneyi, C. amycolatum, and C. hansenii. Bootstrap values (expressed as percentages of 1,000 replications) higher than 50% are given at the branching points. Filled circles indicate that the corresponding nodes (groupings) are also obtained on the parsimony tree. Open circles indicate that the corresponding nodes (groupings) are also obtained on the maximum-likelihood and parsimony trees. Corynebacterium bovis CIP 54.80^T (AY492236) was used as an outgroup. Bar, 1% sequence divergence.
