A promising new antibiotic reported in Nature is derived from a bacterium called Streptomyces platensis, recovered from a South African soil sample.  It is one of 83,000 natural extracts screened for antibiotic activity. The compound may be effective against a whole range of so-called Gram-positive bacteria, including several of the "superbugs" plaguing hospitals, such as Staphylococcus strains resistant to every known antibiotic except vancomycin.
