Phylogenetic tree highlighting the position of Bacteroides timonensis strain AP1T relative to other type strains within the Bacteroides genus. GenBank accession numbers are indicated in parentheses. Sequences were aligned using CLUSTALW, and phylogenetic inferences were obtained using the maximum-likelihood method within the MEGA software. Numbers at the nodes are percentages of bootstrap values obtained from 500 replicates. Prevotella melaninogenica was used as outgroup. The scale bar represents a 2% nucleotide sequence divergence.
