Failure of Duddingtonia flagrans to reduce gastrointestinal nematode infections in dairy ewes

Veterinary Parasitology, 2007
A field study was conducted on three Swiss farms to investigate the efficacy of Duddingtonia flagrans against naturally acquired infections of gastrointestinal nematodes in adult dairy sheep. On each farm the ewes were divided into two equal groups. One group received Duddingtonia during a period of 4 months at a daily dose rate of 10(6) chlamydospores

A technique for the quantification of Duddingtonia flagrans chlamydospores in sheep faeces

Veterinary Parasitology, 2008
Previous observations showed that Duddingtonia flagrans chlamydospores were visualized in McMaster chambers containing faeces of treated sheep. This trial explored the McMaster technique as a tool to quantify chlamydospores in sheep faeces. A range of individual chlamydospore doses (from 19.5 x 10(6) to 177.5 x 10(6)) were offered orally to nine lambs ...

Preparation and application of biocontrol formulation of nematode-trapping fungus-Duddingtonia flagrans

Veterinary Parasitology
The use of nematophagous fungi as a biological control strategy for parasitic gastrointestinal nematodes (GINs) in livestock holds promise as an innovative alternative approach. This study aimed to evaluate the clinical efficacy of a lyophilized Duddingtonia flagrans preparation, utilized in association with the anthelmintics ivermectin or albendazole,

The effect of Duddingtonia flagrans on trichostrongyle infections of Saanen goats on pasture

Veterinary Parasitology, 2003
Four groups of nine Saanen goat does with a naturally acquired mixed trichostrongylid infection were grazed on four paddocks. Two groups received a daily dose of Duddingtonia flagrans at the rate of 5 x 10(7) chlamydospores per animal per day for the 26-day grazing period. After a 19-day pasture resting period, 20 worm free 12-week-old tracer kids were

Effect of silver nanoparticles (AgNP's) from Duddingtonia flagrans on cyathostomins larvae (subfamily: cyathostominae)

Journal of Invertebrate Pathology, 2020
The in vitro effect of silver nanoparticles of the Duddingtonia flagrans filtrate enriched with chitin was evaluated on infective larvae of cyathostomins (L3). After biosynthesis, an assay was carried out with two experimental groups in microtubes, for a period of 24 h: G1 (AgNP's-D. flagrans (43.4 μg/mL) + 120 L3) and G2 (distilled water + 120 L3). At

Biological control using the fungi Duddingtonia flagrans against cyathostomins of horses

Journal of Equine Veterinary Science, 2012
Gastrointestinal parasitism in horses can affect all categories with evident clinical signs. Control is made with the regular use of chemical products, which has cause resistance to all classes of drugs [1, 2]. New alternative control strategies are needed and biological control with the fungi Duddingtonia flagrans is an appropriate option.

Morphological variability, molecular phylogeny, and biological characteristics of the nematophagous fungus Duddingtonia flagrans

Journal of Basic Microbiology, 2019
AbstractThis study aims to investigate the molecular phylogenetic analysis, morphological variability, nematode‐capturing ability, and other biological properties of Chinese Duddingtonia flagrans isolates. We isolated 13 isolates of D. flagrans and found features that have never been reported before, such as two to three septa incluing club‐shaped ...

Duddingtonia flagrans and its crude proteolytic extract: concomitant action in sheep coprocultures

Veterinary Research Communications
The presence of infective larvae (L3) of gastrointestinal nematode (GIN) parasites in pastures directly contributes to the constant recurrence of infections in ruminant herds. This study aimed to evaluate the nematophagous fungus Duddingtonia flagrans (AC001) (proteolytic crude extract and/or conidia) in the in vitro control of GIN L3 in coprocultures.

2014
The ability of predacious fungus Duddingtonia flagrans to survive passage through the digestive tract of horse and subsequently to reduce the number of free-living strongylid larva in the fecal cultures was examined. The fungus has been determined to retain the viability after 6-mounths storage of dry grain preparation at the room temperature and ...
