Application Of Fluorescence In Situ Hybridization For Visualization And Quantification Of Human Gastrointestinal Microbiota, Alexander M. Gordon

Browse all Theses and Dissertations

The microbiota of the human gastrointestinal tract is the focus of current research due to their role in human health and disease. Modern methods characterize the communities of gut microbiota through the use of culture independent techniques. Technologies such as microarrays and next generation sequencing (NGS) determine microbial profiles by analyzing the pool of 16S ribosomal small subunit RNA genes in the community. These techniques operate through the measurement of genomic content rather than through direct analysis of cells. This approach predisposes the methods to discrepancies and bias. In contrast, the use of fluorescence in situ hybridization (FISH) to analyze …
