Developing Regulated Crispr Systems To Control Bacterial Microbiomes, Gregory M. Pellegrino

Electronic Thesis and Dissertation Repository

Changes to the human microbiome’s composition and metabolome are associated with numerous diseases and alterations to xenobiotic metabolism. As such, targeting the human microbiome is an increasingly popular option for therapeutic interventions. However, traditional therapies that target the microbiome such as antibiotics lack specificity, which can affect the beneficial species of the microbiome and cause adverse health outcomes such as the rise of antimicrobial-resistant bacteria. Therefore, the research and development of specific, targeted antimicrobial therapies is crucial to effectively treating microbiome dysbioses.
CRISPR and CRISPRi provide easily modifiable, RNA-guided mechanisms mediated by the Cas9 or dCas9 enzymes to induce sequence-specific …
