Étude expérimentale du cycle biologique de Echinostoma togoensis n. sp., parasite à l’état larvaire de Biomphalaria pfeifferi au Togo [PDF]

Annales de Parasitologie Humaine et Comparée, 1981
The adult and larval stages of Echinostoma togoensis are described. E. togoensis evolves at the reddened stage in the genital gland of Biomphalaria pfeifferi, which it sterilizes completely. Metacercariae develop either in the pericardial cavity of various aquatic Pulmonata or in the kidneys of Amphibian tadpoles.

Extracellular Vesicle Properties and Functions Are Defined by the Originating Cell's Fitness Status

Journal of Extracellular Biology, Volume 5, Issue 2, February 2026.
ABSTRACT Recent studies have focused on the role of dying cells in modulating immune function and shaping the local microenvironment. Apoptotic cells release various extracellular vesicles (EVs), such as exosomes and microvesicles, and form apoptotic bodies through membrane blebbing.

Habitat Structure Shapes Mollusc Assemblages in an Urban Semiarid River: Implications for Conservation and Public Health

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT Fine‐scale environmental drivers shape freshwater mollusc assemblages in urban semiarid rivers. We examined how substrate composition and water chemistry influence mollusc richness and abundance along a polluted stretch of a river in the Brazilian semiarid region. Surveys at five sites recorded 2479 individuals.

Elucidating the life cycle of opossum parasites: DNA sequences reveal the involvement of planorbid snails as intermediate hosts of Rhopalias spp. (Trematoda: Echinostomatidae) in Brazil.

PLoS ONE, 2023
Echinostomatid digeneans belonging to the genus Rhopalias are intestinal trematodes found mainly in opossums in the New World. The genus comprises seven species, but their life cycles and intermediate hosts have been unknown until now.

Genetic Diversity and Ecological Distribution of Bulinus Populations in Southern Benin Using PCR‐RFLP Analysis

BioMed Research International, Volume 2026, Issue 1, 2026.
Schistosomiasis remains a major public health concern in Benin. Freshwater snails of the genus Bulinus serve as intermediate hosts for schistosomes, trematode parasites responsible for bilharzia. The urinary form, caused by Schistosoma haematobium, is the most prevalent and is primarily transmitted by Bulinus truncatus and Bulinus globosus, whereas the

Great minds map alike: Citizen and expert distribution models of schistosome snail hosts in rural west Uganda

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Citizen scientists and an expert jointly monitor Biomphalaria snails (the intermediate host of Schistosoma mansoni) in rural areas of southwest Uganda, generating over 4500 georeferenced records. By comparing expert‐ and citizen‐based distribution models under perfect and imperfect detection, we demonstrate that site type and NDVI consistently ...
