Many of the most widely used antibiotics have come out of the dirt. Penicillin came from Penicillium, a fungus found in soil, and vancomycin came from a bacterium found in dirt. Now, researchers from Northeastern University and NovoBiotic Pharmaceuticals and their colleagues have identified a new Gram-positive bacteria-targeting antibiotic from a soil sample collected in Maine that can kill species including methicillin-resistant Staphylococcus aureus (MRSA) and Mycobacterium tuberculosis. Moreover, the researchers have not yet found any bacteria that are resistant to the antibiotic, called teixobactin.
