To develop and evaluate a naive Bayesian classifier that rapidly and accurately assigns bacterial 16S rRNA sequences into new higher-order taxonomies from domain down to genus.
Evaluated the Ribosomal Database Project (RDP) Classifier using leave-one-out cross-validation on 5,014 type strain sequences from Bergey's Taxonomic Outline.
Tested the classifier against an additional corpus of 23,095 rRNA sequences classified under alternative NCBI taxonomy.
Assessed performance across full-length sequences, 400-base segments, and variable regions (such as V2 and V4) relevant to pyrosequencing.
Generated high estimated confidence (≥95%) and high accuracy (98%) in 98% of type strain classifications.
Maintained overall accuracies of 89% or higher down to the genus level across both corpora for near-full-length and 400-base segments.
Identified that classification error rates for shorter fragments vary by gene region, with the lowest error rates occurring near the V2 and V4 variable regions.
