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

The research paper explores how carnivorous fungi hyphomycetes naturally regulate the size of parasitic nematodes, specifically equine strongyle larvae, indicating that they can greatly reduce the larvae’s size.

General Overview

• The paper presents a study on the impact of carnivorous fungi hyphomycetes on soil nematodes. These fungi are found to be a natural antagonist of nematodes, reducing their size significantly.
• The significant strain focused on this study is Duddingtonia flagrans T-89, which has shown to reduce the size of equine strongyle larvae by 5 to 48 times under the influence of the fungus.

Methodology

• The researchers carried out laboratory tests on nematode-infected mice to observe the effect of the Duddingtonia flagrans biopreparation. Mice were fed with this biopreparation to study its impact.
• The focus of the study was also on the viability and development of the carnivorous fungus D. flagrans’s chlamydial spores within the excrement of these mice.

Results and Conclusions

• The study observed that dead nematodes exhibited cell structural impairment across all their tissues and organs, which researchers believe could be due to the substances found within the cell envelope of the Duddingtonia flagrans fungus. This suggests that the fungi not only reduce the size of the nematodes but also damage their cellular structures, contributing to their mortality.
• The fungi hyphomycetes, in particular the Duddingtonia flagrans strain, are evidenced as a natural regulator of parasitic nematodes. This indicates the potential use of such fungi in controlling parasitic nematode populations and reducing infection rates.
