Ecological and evolutionary forces shaping microbial diversity in the human intestineCell Mol Life SciIn addition to massive datasets, new questions are being posited that challenge the abilities of current algorithms to deliver meaningful answers in the context of biology and medicinein ulcerative colitisFor more information, visit the cookies pageDespite the fact that DNA pyrosequencing yields relatively short read lengths and limited amounts of sequence data per pathogen or microbe, this strategy has been useful for microbial identification in different settingspp[PubMed]38Microbiol ImmunolScience
One metagenomic study describes the complex gastrointestinal microbiota as spanning only 9 of 55 bacterial phylogenetic groups, with two predominant phyla including Bacteroidetes and Firmicutes (50)2006;103:112405Rapid and accurate pyrosequencing of angiosperm plastid genomesThe generation of consensus sequences based on assembly of overlapping reads from a single genome is not an available option for metagenomics studies, and newly developed strategies are required to minimize error rates for such community sequencing endeavorscurrently receives support from the National Institutes of Health (NIH) (NIDDK R01 DK065075; NCCAM R01 AT004326; NCCAM R21 AT003482), the Office of Naval Research, and the Defense Advanced Research Projects Agency (DARPA)Reductions in microbial diversity have been associated with human disease phenotypes (64), and such diversity indices may be relevant to medical diagnostics in the future2004;5:113As a universal approach to bacterial pathogen identification, a two-region approach yielded bacterial genus identifications in approximately 90% of isolates not amenable to biochemical identification (17)The clinical laboratory will need to significantly enhance its computing infrastructure and pipelines in the near future to accommodate this demand, especially in academic centers and universities.Beginning with sequence collection and verification, algorithms must be in place to trim sequences and vet the quality of individual reads using various strategies (FigNovel genes and functions are being discovered as a result of massive datasets obtained by whole genome shotgun sequencing of marine samples (53)
2001;199:1037In addition to the phenotypic dimension of human biology such as gene expression profiling, proteomics, and metabolomics, perhaps we need to extend our concept of the human genome to include the more comprehensive and plastic human metagenome in laboratory medicinehave active funding from the NIH (NHGRI) including support for the Jumpstart phase of the Human Microbiome Project2005;71:772436The relatively “long" reads generated by 454 sequencing allow more frequent unambiguous mapping to complex targets, than do the products of the other ‘short read’ NexGen technologiesSequence query tools such as SeqMatch in RDP II enable relatively short query sequences that are 50 or more bases in length to yield accurate microbial identificationsAnal BiochemGreengenes, a chimera-checked 16S rRNA gene database and workbench compatible with ARB[PubMed]42 87c6bb4a5b
