Control of Strongyloides westeri by nematophagous fungi after passage through the gastrointestinal tract of donkeys.
Abstract: Strongyloides westeri is the most prevalent nematode among equines aged up to four months and causes gastrointestinal disorders. The objective of this study was to observe the control of infective S. westeri larvae (L3) by the nematophagous fungi Duddingtonia flagrans (AC001) and Monacrosporium thaumasium (NF34) after passage through the gastrointestinal tract of female donkeys. Twelve dewormed female donkeys that were kept in stables were used. Two treatment groups each comprising four animals received orally 100 g of pellets made of sodium alginate matrix containing a mycelial mass of either D. flagrans (AC001) or M. thaumasium (NF34). The control group consisted of four animals that received pellets without fungus. Feces samples were then collected from the animal groups at different times (after 12, 24, 48 and 72 hours). These feces were placed in Petri dishes containing 2% water-agar medium and 1000 L3 of S. westeri. AC001 and NF34 isolates showed the ability to destroy the L3, after gastrointestinal transit, thus demonstrating their viability and predatory activity.

The research article is about observing the impact of two types of nematophagous fungi on the control of a prevalent nematode species in young equines after passage through the digestive system of female donkeys.
Objective and Methodology
- This study aimed to assess the action of two nematophagous fungi, Duddingtonia flagrans (AC001) and Monacrosporium thaumasium (NF34), on Strongyloides westeri larva (L3).
- This nematode is the most common among equines aged up to four months and can cause gastrointestinal issues.
- Twelve dewormed female donkeys kept in stables were used for the experiment. They were divided into three groups; with two treatment groups of four animals each, and one control group.
- Both treatment groups were orally administered 100 grams of pellets containing a mycelial mass of one of the two fungi embedded in a sodium alginate matrix. The control group received fungus-free pellets.
Sample Collection and Analysis
- Fecal samples were collected from each experimental group at various intervals (12, 24, 48, and 72 hours post-administration).
- These samples were placed in Petri dishes that contained 2% water-agar medium and 1000 L3 of S. westeri.
- The aim was to monitor the predatory action of the fungal isolates on the nematode larvae after being passed through the gastrointestinal tract.
Findings and Conclusion
- Both D. flagrans (AC001) and M. thaumasium (NF34) exhibited the ability to destroy the infectious larvae of S. westeri after transitioning through the donkey’s gastrointestinal tract.
- This evidence shows their viability and predatory activity against this nematode species.
- Based on these findings, these two fungi could be used as a potential biocontrol tool against this prevalent parasitic nematode in equines.
