"Uncovering Soil Bacteria's Novel Antimicrobial Weaponry"
Researchers have discovered umbrella-shaped toxic protein particles secreted by soil bacteria Streptomyces to inhibit the growth of competing species, particularly others of their own genus. These large complexes, unlike small-molecule antibiotics, are highly specific in targeting bacteria and have evaded discovery for over a century. The discovery, published in Nature, sheds light on the bacteria's combative strategies and potential clinical applications, including combating antibiotic-resistant bacteria such as those causing tuberculosis and diphtheria.
