Rockefeller Scientists Map Genetic Interactions in Tuberculosis Bacteria, Paving Way for Better Antibiotic Pairings

Researchers at Rockefeller University have built the most comprehensive map yet of how essential genes interact in Mycobacterium tuberculosis, the bacterium that causes tuberculosis. The map uncovers thousands of previously unknown genetic relationships, providing a new window into the pathogen's inner workings. This breakthrough could help identify effective antibiotic combinations, a pressing need as drug-resistant TB strains spread globally. By revealing which genes work together or buffer each other, the map may guide the development of therapies that hit multiple targets at once, making it harder for bacteria to evolve resistance. The work matters because TB remains one of the world's deadliest infectious diseases, killing over a million people each year. With this map, scientists can now explore new strategies to combat the disease more effectively.
