Scientists successfully created a genetically engineered bacterium that produces a safer version of an antifungal drug called pimaricin. The new version, called disaccharide-pimaricin, dissolves much better in water and causes significantly less damage to human blood cells, making it a much safer option for treating fungal infections. Although it’s slightly less effective at killing fungi, the improvement in safety and solubility makes it a promising candidate for treating eye infections and other fungal diseases.
