[Study of antiviral activity of extracts obtained from basidial fungi against influenza viruses of different subtypes in experiments in vitro and in vivo].

Aim: To study antiviral activity of extracts obtained from basidial fungi against influenza viruses of different subtypes.

Materials And Methods: Antiviral activity of extracts obtained from basidial fungi against influenza virus A/chicken/Kurgan/05/2005 (H5N1) was determined in in vitro experiments. Changes in infectiousness of pandemic influenza virus A/Moscow/226/2009 (HIN1)v caused by extracts of basidial fungi was studied in experiments in vitro and in vivo.

[Antiviral activity of aqueous extracts and polysaccharide fractions from mycelium and fruit bodies of higher fungi].

Sixty preparations of basidiomycetes (Ganoderma, Lentinus, Pleurotus, Laetiporus, Polyporus, Inonotus, Flammulina, Grifola, Trametes) were investigated with respect to their toxicity for Vero cells and antiviral activity. The antiviral activity was estimated with the use of the West Nile virus and type 2 Herpes simplex. It was shown that 11 preparations of Ganoderma, Lentinus and Pleurotus completely inhibited the infective activity in doses not lower than 1000 TCD50 (the West Nile virus) and 100 PPU (type 2 Herpes simplex).

[The carnivorous fungi hyphomycetes are natural regulators of the size of animal parasitic nematodes].

The carnivorous fungi hyphomycetes are natural enemies of soil nematodes. Laboratory tests examining the effect of the effective strain Duddingtonia flagrans T-89 on equine strongyle larvae have indicated that their size can be reduced 5-48-fold under the action of the fungus. Using helminth-infected mice as an example has ascertained that when the animals are fed a biopreparation, the chlamydial spores of the carnivorous fungus D.
