16S and Internal Transcribed Spacer (ITS) ribosomal RNA (rRNA) sequencing are common amplicon sequencing methods used to identify and compare bacteria or fungi present within a given sample. Both ITS and 16S rRNA gene sequencing are well-established methods for comparing sample phylogeny and taxonomy from complex microbiomes or environments that are difficult or impossible to study.
Unlike capillary sequencing or PCR-based approaches, next-generation sequencing (NGS) is a culture-free method that enables analysis of the entire microbial community within a sample. An additional advantage of NGS-based 16S and ITS rRNA sequencing methods is that they provide a cost-effective technique to identify strains that may not be found using traditional methods. Furthermore, NGS offers the ability to combine multiple samples in a sequencing run.
