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

Abstract

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 the end of this period, AgNP's-D. flagrans (G1) demonstrated an effect on L3 with a 43% reduction (p < 0.01) in relation to G2. Thus, the authors suggest new designs with AgNP's-D. flagrans for the control of cyathostomins.
