ENHANCED TREATMENTS TO KILL OR DEBILITATE PATHOGENIC MICROORGANISMS OF A MAMMALIAN BODY

摘要

Present invention relates to a composition of matter and a method that improves treatments to inactivate, kill and debilitate pathogenic microorganisms that infect on or within a mammal body, such as Helicobacter pylori. The composition of matter comprises anti-adhesive polysaccharide molecules to abolish or reduce the adhesion of H. pylori to themselves and to gastric mucin without affecting the viability of either bacteria or gastric epithelial cells. Polysaccharides isolated from seaweed are preferred anti-adhesive materials and fucoidans is a most preferred embodiment. To facilitate bacteria eradication, methods include the administration of fucoidans before, during and/or after other killing and destroying physical or chemical therapy. The inhibition or impairment of the mechanism of bacterial adhesion due to the treatment with fucoidans is aimed to diminish colonization and pathogenesis of pathogenic bacteria by making them more fragile or susceptible to killing or destroying therapies. The combined use of fucoidans with PDT is a preferred method to eradicate H. Pylori in the gastrointestinal tract.
