From 'Earthweek', The Columbus Dispatch, May 15, 2010 Australian scientists said they have discovered a naturally occurring compound found in seaweed off the coast of Tasmania that can prevent infection by the H1N1 influenza strain. Helen Fitton of Marinova Laboratories said the 'fucoidan' compound blocks the ability of the virus to use receptors to get into cells. "With swine flu already becoming resistant to some other antiviral agents, we believe that the extract---known as Maritech 926---offers a potent, natural alternative which supports the immune system against viral attacks," Fitton said. Marinova's managing director, Paul Garrott, said he expects the compound will be used in nasal sprays, hand washes and tablets once human trials are completed.
