Taxonomic Deception via Obvious Traits: Oversplitting in European Vallonia Risso, 1826 (Mollusca: Gastropoda: Valloniidae)

Zoologica Scripta, Volume 55, Issue 1, Page 37-51, January 2026.
ABSTRACT The status of the six traditionally recognised European Vallonia taxa is considered based on mtDNA and nDNA sequences from five independently sorting loci in combination with morphometric landmark analyses conducted on genetically confirmed shells. These analyses document that only two species are valid (V. costata and V.

Small‐Scale Field Trials to Assess the Molluscicidal Activity of Hagenia abyssinica Against Biomphalaria Snail Species

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
Schistosomiasis remains a significant public health burden in many developing countries. Plant‐based molluscicides have gained considerable attention as alternatives for snail control, owing to their relatively lower toxicity and favorable environmental profile. However, prior to large‐scale application, plant‐based molluscicides require rigorous small‐

Trematode Infection Prevalence Increases With Snail Richness: Observations From a 4‐Year Study of Snail–Trematode Interactions

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We find that higher snail richness correlated with increased overall and generalist trematode infections, while specialist infections showed a similar but nonsignificant trend. The study also highlighted potential host‐switching events and the impact of long‐term sampling on parasite communities, emphasizing the need for continued monitoring of host ...

Estudo fitoquímico e avaliação da atividade moluscicida do Calophyllum brasiliense Camb (Clusiaceae) Phytochemical study and evaluation of the molluscicidal activity of Calophyllum brasiliense Camb (Clusiaceae)

Química Nova, 2005
The bioassay-guided fractionation against Biomphalaria glabrata of hydroalcoholic extracts of Calophyllum brasiliense aerial parts led to the isolation of the coumarin, named (-) mammea A/BB.

The significance of the amoebocyte-producing organ in Biomphalaria glabrata [PDF]

Memórias do Instituto Oswaldo Cruz, 2012
In molluscs, internal defence against microorganisms is performed by a single cell type, i.e., the haemocyte or amoebocyte. The origin of these cells in Biomphalaria glabrata was initially thought to be localised within the vasculo-connective tissue.

Pharmacological Inhibition of c‐Jun N‐Terminal Kinase Activity Exacerbates Liver Damage in Schistosoma mansoni Infected Mice

Liver International, Volume 45, Issue 9, September 2025.
ABSTRACT Background and Aims Schistosomiasis is a neglected tropical disease affecting more than 250 million people worldwide. Eggs of the parasitic helminth S. mansoni cause major morbidity in the liver, spleen and intestine. Of note, egg‐released soluble antigens (SEA) induce the transcription factor c‐Jun in hepatocytes, promoting hepatocellular ...

CRISPR/Cas9 Knockout of Shell Matrix Protein 1 in the Slipper‐Snail Crepidula atrasolea

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 5, Page 266-283, July 2025.
Methods for CRISPR/Cas9 shell matrix protein knockout in the snail, Crepidula atrasolea including optimizing RNP delivery and embryo husbandry, to the use of Sanger and MiSeq sequencing, and high‐content screening of embryos to characterize the loss of Shell Matrix Protein 1 (SMP1) during larval shell development.
