Figure 2

Phylogenetic tree based on 16S rRNA gene sequences of N. otitidiscaviarum clinical isolates, and other representative species of the Nocardia genus. Sequences of strains isolated in this work are indicated in bold letters. Sequences were aligned using the MUSCLE software version 3.6. The recovered ML phylogram based on the common 1311-nucleotide stretch is shown. Numbers represent ML bootstrap (> 50%). The sequence of Rhodococcus opacus was used as out-group. The scale bar indicates 0.01 substitutions per nucleotide position. Accession numbers are given in parentheses. ^T means type strain.
