Development of an in vitro drug sensitivity assay based on newly excysted larvae of Echinostoma caproni [PDF]

open access: yes, 2013
Echinostomiasis is one of the major food-borne trematodiases and the species Echinostoma caproni serves as a useful model for trematocidal drug discovery. The current in vitro drug sensitivity assay uses adult E.

New data on the morphology and phylogenetic connections of Postlepidapedon opisthobifurcatum (Trematoda, Lepocreadioidea: Lepidapedidae), a parasite of Antarctic and sub-Antarctic fishes

open access: yesHelminthologia, 2018
The trematode Postlepidapedon opisthobifurcatum (Zdzitowiecki, 1990) is a common intestinal parasite of the gadiform fishes of the Southern Ocean. In this work, we supplement the description of the species with the anatomy of the terminal part of the ...

Botaurus pinnatus (Wager, 1829) (Ave: Ardeidae) in Brazil as a new host of Clinostomum heluans Braun 1901 (Digenea: Clinostomidae)

open access: yesHelminthologia, 2017
This paper reports the occurrence of Clinostomum heluans Braun 1901 (Digenea: Clinostomidae) in a specimen of Botaurus pinnatus (Wager, 1829) (Ave: Ardeidae) found in southeastern Brazil. Although this parasite has been reported in other birds in Brazil,

In vitro and in silico study on the seeds of Veitchia merrillii on trematode worms [PDF]

open access: yesVeterinary World
Background and Aim: The potential of plants as anthelmintics is very large, but there is still very little research conducted in the search for effective, safe, easily obtained, and affordable anthelmintic candidates.

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

Marine Parasite Biogeography Mirrors Host Patterns Across Latitude, Area, and Diversity

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Parasites are integral components of biodiversity, yet they remain poorly represented in large‐scale biogeographic theory. In this study, we test whether marine parasites follow three macroecological patterns established for free‐living taxa, namely that parasite species richness: (1) scales positively with area (both host body size and geographic area)
