Algal Extracts as Potent Antiviral Agents: A Promising Frontier in Viral Infection Management

Explore the potential of algal extracts as novel antiviral agents based on historical antimicrobial findings from the 1940s. Recent studies highlight the efficacy of algal compounds in inhibiting various viruses. Discover the antiviral mechanisms and activity of select algae such as Caulerpa taxifolia, Spirulina platensis, and Cyanovirin-N. Gain insights from a personal antiviral study using Spirulina and understand the importance of proper experimental setup. Uncover the promising role of algal sulfated polysaccharides against a spectrum of viruses.

  1. Alga Extracts as Novel Antiviral Agents By Stephanie Boone

  2. Background • Antimicrobial activity of alga was first reported in 1940 (antibacterial activity of Chorella vulgaris). • The antimicrobial properties of seaweed reported in 1951. • Antiviral effects of polysaccarides from marine alga reported to inhibit mumps, and influenza B virus. • 1969 extracts from red algae inhibited HSV and other viruses. • These observations generated little interest due to nonspecificity.

  3. Antiviral Activity Caulerpa taxifolia Inhibited FIV in vitro Blue-green algae (allophycocyanin) Neutralized enterovirus 71 cytopathic effect in vitro Blue-green algae (Cyanovirin-N) Inactivates HIV Spirulina platensis Inhibits HIV activity Spirulina platensis (calcium spirulan) Inhibits HSV-1, human cytomegalovirus (HCMV), measles virus, mumps virus, influenza virus and HIV-1 Alga Sulfated polysaccharides HIV, herpes simplex 1&2, influenza A, RSV, SIV, pseudorabies, bovine herpes and HCMV

  4. Antiviral Mechanisms

  5. My Antiviral Study • METHOD • Grew a lawn of bacteria on TSA plate. • Used bacteria phage assay. PRD-1 was placed in top agar. • Applied Spirulina from health food store to plates in diluted form. • Watched growth over 24 hour period. • Counted plaques.

  6. Study Results • No difference between treated plates and plates not treated. • Assay failed.

  7. Conclusions: Never work with algae in a bottle from the health food store. Study Conclusions

  8. References • Available upon request.
