How Do Trematodes Induce Cancer? A Possible Evolutionary Adaptation of an Oncogenic Agent Transmitted by Flukes

open access: yesEvolutionary Applications, Volume 18, Issue 1, January 2025.
ABSTRACT There is strong epidemiological evidence that development of various cancer types is linked to infection with flukes (Platyhelminthes: Trematoda) in Africa, Asia and the Middle East. The exact nature of the mechanism by which cancer is induced by these parasites is unknown.

Pest categorisation of non‐EU Scolytinae on non‐coniferous hosts

open access: yesEFSA Journal, Volume 22, Issue 9, September 2024.
Abstract The EFSA Panel on Plant Health performed a group pest categorisation for the EU territory of non‐EU Scolytinae (Coleoptera: Curculionidae) on non‐coniferous hosts, which total 6495 known species. Most species attack apparently healthy, weakened or dead trees, either feeding on the phloem (‘bark beetles’ subgroup) or on fungi inoculated into ...

Cannibalism and competition can increase parasite abundance for parasites with complex life history strategies

open access: yesEcology, Volume 105, Issue 7, July 2024.
Abstract Ecological interactions among hosts are critical to consider when predicting disease dynamics. Most theory predicts that intraguild predation (IGP) and cannibalism negatively impact parasite populations, but this is based primarily on assumptions of simple or single‐host life cycles.

Gland cells in the redia of Fasciola hepatica

open access: yesParasitology, 1972
Gland cells surrounding the oesophagus in the redia of Fasciola hepatica are described. These cells produce electron-dense, membrane-bound vesicles which have an unusual mechanism for secretion of their contents.

Density‐dependent effects of parasitism on the activity of a benthic engineer species: potential impact on ecosystem functioning

open access: yesOikos, Volume 2024, Issue 4, April 2024.
While parasitism is a common lifestyle on Earth, its importance for the functioning of marine ecosystems has been overlooked for a long time. In particular, parasites have significant potential to influence central ecological processes through their impacts on hosts that serve as ecosystem engineers.

Prevalence, treatment and control of hypertension in La Réunion: the RÉDIA population-based cohort study

open access: yesBlood Pressure, 2017
A better knowledge of prevalence, management and determinants of hypertension is needed in regions in epidemiological transition to adapt the strategies of public health screening and prevention, and to reduce the burden of cardiovascular diseases.
