Staphylococcus killing seaweed. Powdered extract taken from seaweed, which acts as an antidote against antibiotic resistant Staphylococcus aureus bacteria. The seaweeds seen here are Fucus sp. It is not the actual seaweed, but bacteria on the seaweed, notably Planococcus sp. bacteria, that yield the extract. Tests show that the deadly MRSA bacterium (Methicillin-resistant Staphylococcus aureus) succumbs to this chemical. MRSA is common in hospitals, infecting wounds of patients, and is resistant to all other agents. This seaweed agent may be produced synthetically to serve as a natural antibiotic drug. Research conducted at Heriot-Watt University, Edinburgh, Scotland.
