Assessment of Bifidobacterium Species Using groEL Gene on the Basis of Illumina MiSeq High-Throughput Sequencing
AbstractThe next-generation high-throughput sequencing techniques have introduced a new way to assess the gut’s microbial diversity on the basis of 16S rRNA gene-based microbiota analysis. However, the precise appraisal of the biodiversity of Bifidobacterium species within the gut remains a challenging task because of the limited resolving power of the 16S rRNA gene in different species. The groEL gene, a protein-coding gene, evolves quickly and thus is useful for differentiating bifidobacteria. Here, we designed a Bifidobacterium-specific primer pair which targets a hypervariable sequence region within the groEL gene that is suitable for precise taxonomic identification and detection of all recognized species of the genus Bifidobacterium so far. The results showed that the novel designed primer set can specifically differentiate Bifidobacterium species from non-bifidobacteria, and as low as 104 cells of Bifidobacterium species can be detected using the novel designed primer set on the basis of Illumina Miseq high-throughput sequencing. We also developed a novel protocol to assess the diversity of Bifidobacterium species in both human and rat feces through high-throughput sequencing technologies using groEL gene as a discriminative marker.
