Here, we investigated whether gut bacteria affect the progression of Huntington\u2019s disease (HD) in transgenic\n                    <jats:italic>Drosophila melanogaster<\/jats:italic>\n                    (fruit fly) models expressing full-length or N-terminal fragments of human mutant huntingtin (HTT) protein. We find that elimination of commensal gut bacteria by antibiotics reduces the aggregation of amyloidogenic N-terminal fragments of HTT and delays the development of motor defects. Conversely, colonization of HD flies with\n                    <jats:italic>Escherichia coli<\/jats:italic>\n                    (\n                    <jats:italic>E. coli<\/jats:italic>\n                    ), a known pathobiont of human gut with links to neurodegeneration and other morbidities, accelerates HTT aggregation, aggravates immobility, and shortens lifespan. Similar to antibiotics, treatment of HD flies with small compounds such as luteolin, a flavone, or crocin a beta-carotenoid, ameliorates disease phenotypes, and promotes survival. Crocin prevents colonization of\n                    <jats:italic>E. coli<\/jats:italic>\n                    in the gut and alters the levels of commensal bacteria, which may be linked to its protective effects.
