Antibiotic "megacluster" discovery provides new strategy to fight superbugs
Summary
Scientists discovered a large group of genes called a "megacluster" in certain bacteria that produce four molecules working together to block an important process bacteria need to survive. This new finding could lead to better antibiotics to fight resistant bacteria by attacking their vitamin-making system.Key Facts
- Antibiotic resistance makes some bacterial infections hard to treat.
- Most antibiotics today come from natural molecules made by microbes.
- New antibiotics are harder to find, and resistance is increasing.
- Researchers found a "megacluster" of genes that produce four molecules targeting the biotin (vitamin B7) production pathway in bacteria.
- These molecules work together to block different steps in biotin production, which bacteria need to grow and cause disease.
- The megacluster was found in Streptomyces bacteria, known sources of many antibiotics.
- Traditional methods look for single molecules, but this megacluster produces multiple molecules that attack bacteria in different ways.
- This discovery offers a new method to find and use antibiotics against resistant bacteria.
