Evaluating the In Vitro Anthelmintic Activity of Zinc Oxide Nanoparticles (ZnO‐NPs) Against the Adult Stages of Fasciola hepatica

open access: yesVeterinary Medicine and Science, Volume 11, Issue 1, January 2025.
Resistance to currently deployed flukicide is a growing health problem. This study evaluated the in vitro anthelmintic activity of zinc oxide nanoparticles (ZnO‐NPs) at 0.05, 0.10 and 0.12 mg/mL against Fasciola hepatica. The fastest mortality and paralysis rates of flukes were obtained at 0.12 mg/mL of ZnO‐NPs. Furthermore, SEM results showed complete

Spermatogenesis in the hermaphroditic Digenea (Trematoda)

open access: yesParasitology, 1965
While some variation of detail may be found in different species of the hermaphroditic Digenea, the process of spermatogenesis conforms to a common plan throughout the group. There is divergence of opinion concerning the interpretation of the structure of the ripe spermatozoon.In the testis of a young animal, primary, secondary and tertiary ...

Reinvestigation of the sperm ultrastructure of Hypoderaeum conoideum (Digenea: Echinostomatidae) [PDF]

open access: yesParasitology Research, 2018
Spermatological characteristics of the digenean Hypoderaeum conoideum (Echinostomatidae) collected from Anas platyrhynchos in the Lac d'Annecy (France) were reinvestigated using transmission electron microscopy. The previous study on this species only describes the presence of two axonemes of unequal lengths, a mitochondrion, a posterior nucleus, and ...

Unclear host taxonomy hinders parasite studies: An up‐to‐date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae)

open access: yesJournal of Fish Biology, Volume 105, Issue 6, Page 1501-1539, December 2024.
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...
