Antiprotozoal Activity of Mycelial Extracts of Several Medicinal Agaricomycetes Mushrooms against Giardia duodenalis

Summary

This research investigated how extracts from medicinal mushrooms could be used to fight parasitic infections, specifically Giardia which causes intestinal illness. Scientists found that one mushroom species, Polyporus lipsiensis, was particularly effective at killing these parasites. This discovery could lead to new natural treatments for parasitic infections. Impacts on everyday life: • Could provide alternative treatments for people with parasitic infections who don’t respond to conventional drugs • Demonstrates the potential of mushrooms as sources of natural medicines • May lead to development of safer, natural antiparasitic treatments with fewer side effects • Could help address the growing problem of drug resistance in parasitic diseases • Shows promise for sustainable medicine production using mushroom cultivation

Background

Despite existing knowledge about therapeutic properties of fungal bio-compounds, limited research has been conducted on their anti-parasitic activities. Giardia duodenalis is a significant parasitic pathogen that requires new treatment approaches due to increasing drug resistance.

Objective

To evaluate the anti-parasitic activity of mycelial extracts from seven medicinal agaricomycetous mushrooms against Giardia duodenalis, and to identify the chemical compounds produced by Polyporus lipsiensis mycelium.

Results

P. lipsiensis demonstrated the highest antiparasitic activity among tested species. GC-MS analysis of P. lipsiensis mycelial extract identified 73 different molecules, including steroids, terpenes, and lipids. Of these compounds, 11 were found to possess antiparasitic activity according to literature data.

Conclusion

The study revealed significant diversity in compounds with anti-protozoal potential produced by Agaricomycetes mushrooms, with P. lipsiensis showing particular promise against G. duodenalis. This research highlights the potential of medicinal mushrooms as sources of natural antiparasitic compounds.
