Nueva especie de Planorbidae (Gastropoda: Basommatophora) en la Patagonia chilena: Biomphalaria cristiani sp. nov.

Latin American Journal of Aquatic Research, 2012
En Chile la familia Planorbidae está representada por el género Biomphalaria Preston, 1910, compuesta por siete especies distribuidas desde Isluga hasta el río Puelo. De estas especies, solo B.peregrina, ampliamente distribuida en el neotrópico, y Biomphalaria aymara de Isluga, han sido reconocidas sobre la base de la morfología del sistema reproductor

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.

Characterization of Transcriptional, Epigenetic, and Phenotypic Plasticity and Discovery of Biomarkers in Acute and Chronic Murine Schistosomiasis Infection

The FASEB Journal, Volume 40, Issue 3, 15 February 2026.
Workflow for discovering parasitological and molecular changes related to Schistosoma mansoni infection. ABSTRACT Parasites can induce changes in their hosts, favoring the success of the infection and its development at each stage of their life cycle.

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.

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.

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.

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
