In situ analysis of gene expression patterns in natural microbial communities has long captured the scientific community interest. Recently microbial gene expression has been monitored in both human [1,2] and non-human animal [3-5] environments, including the mouth, skin and the gut. Microbial communities have been studies using several different analysis approaches, including the analysis of 16S ribosomal variable regions and direct sequencing of the “metagenome”. However, metatrascriptomics is a more powerful tool for understanding microbial processes within communities and consortia as it not only reveals the organisms present, but also provides information on their function and how this is influenced in different environments.
