Eligo Publishes in Nature a Landmark Study That Unlocks Genome Editing of Bacteria in the Gut

"What Eligo has achieved shows that it's now possible to make specific changes to the DNA of bacteria in the gut, similar to how scientists have been editing human genes to investigate or treat genetic disorders," said David Bikard, cofounder of Eligo Bioscience and researcher at the Institut Pasteur in Paris.

Eligo demonstrated the ability to engineer a bacteriophage-derived capsid containing a synthetic DNA payload encoding a base-editor system. After oral administration to mice, the capsid delivered the payload with extreme efficiency to target bacterial populations residing among the hundreds of bacterial species in the mouse gut. Remarkably, the system could precisely inactivate antibiotic resistance genes by creating single-base pair mutations in the corresponding genes. When targeting E. coli strains, the technology modified the target gene in over 90% of the bacteria, reaching up to 99.7% in some cases.

Jesus Fernandez, Eligo VP of Technology and a senior author of the study, highlights how "this achievement is the culmination of eight years of work by the team at Eligo Bioscience and represents a paradigm shift in microbiome research. This leap forward provides Eligo with a unique edge within the industry to develop novel genetic medicines, as well as to find novel targets. We finally now have a tool to interrogate the role of specific bacterial genes in health and disease."
