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.

Long-term controlled field experiment on the competition between two species of Biomphalaria (Mollusca, Basommatophora), the snail vectors of Schistosoma mansoni in Northeastern Brazil Estudo experimental de campo sobre a competição entre duas espécies de Biomphalaria (Mollusca, Basommatophora), vetores do Schistosoma mansoni no Nordeste do Brasil

Cadernos de Saúde Pública, 1993
A long-term controlled field experiment on the interactions of the populations of Biomphalaria glabrata (target population) and B. straminea (competitor) was carried out in the county of Alhandra, state of Paraíba, Brazil, during the period 1980 through ...

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 ...

Contribution to the histology of Biomphalaria glabrata [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 1999
A combination of histological techniques applied to the study of Biomphalaria glabrata yielded some interesting new data about the histology of this snail, a major intermediate host of Schistosoma mansoni in Brazil. Three kinds of pigments were identified: a dark pigment which bleached following oxidation with potassium permanganate; a lipofuchsin-like,

Proteomic Analysis of Biomphalaria glabrata Hemocytes During in vitro Encapsulation of Schistosoma mansoni Sporocysts

Frontiers in Immunology, 2018
Circulating hemocytes of the snail Biomphalaria glabrata, a major intermediate host for the blood fluke Schistosoma mansoni, represent the primary immune effector cells comprising the host's internal defense system.

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 ...

On the origin of the Biomphalaria glabrata hemocytes [PDF]

Memórias do Instituto Oswaldo Cruz, 2006
A histologic, morphometric and ultrastructural study performed on Biomphalaria glabrata submitted to infection with Schistosoma mansoni miracidia failed to provide significant evidences that the so-called amebocyte-producing organ (APO) is really the central organ for hemocyte production.
