Unexpected Shifts in Bivalve Function From Filtration to Transmission Risk

open access: yesFreshwater Biology, Volume 70, Issue 6, June 2025.
ABSTRACT Understanding the complex interactions between filter‐feeding species and zoonotic disease transmission in aquatic environments is crucial for accurately quantifying the ecosystem services provided by these organisms. This study explores for the first time the roles of freshwater bivalves in the transmission dynamics of emerging zoonotic ...

The Pampulha reservoir remains a potential urban focus of schistosomiasis mansoni in Brazil: changes in the occurrence patterns of Biomphalaria species and a new record of the parasite

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 2013
Introduction The Pampulha reservoir has long been a focus of schistosomiasis transmission in Belo Horizonte, State of Minas Gerais, Brazil. The last malacological study conducted in this urban reservoir was more than two decades ago, and thus, an update ...

The Innate Immune Sensor Zbp1 Mediates Central Nervous System Inflammation Induced by Angiostrongylus Cantonensis by Promoting Macrophage Inflammatory Phenotypes

open access: yesAdvanced Science, Volume 12, Issue 11, March 20, 2025.
This study reveals that Zbp1 plays a pivotal role in regulating neuroimmune interactions during Angiostrongylus cantonensis (AC) infection. Zbp1 modulates lymphocyte infiltration and natural killer (NK) cell cytotoxicity by promoting cytokine secretion and M1 polarization of macrophages, shaping the CNS immune microenvironment.

Purification, Biochemical Characterization and Digestive Stability Analysis of the Major Allergen Paramyosin From Haliotis discus hannai

open access: yesJournal of Food Biochemistry, Volume 2025, Issue 1, 2025.
Paramyosin (PM) is a structural protein in invertebrates, playing an important role in maintaining the texture of muscle. Although PM has been identified as a major allergen, its characteristics have not been well investigated. In this study, PM with a molecular mass of 97 kDa was purified to homogeneity from Haliotis discus hannai using ammonium ...

Diet of schistosome vectors influences infection outcomes

open access: yesEcosphere, Volume 15, Issue 11, November 2024.
Abstract Resource availability can alter infection outcomes through its impact on host immunity and on parasite reproduction. On one hand, enhanced nutrition could favor immunity, limiting the parasite, and on the other hand, it could favor establishment and reproduction of the parasite.

Multi‐Environment Quantification of Parasite and Intermediate Host DNA on Pasture for Fine‐Scale Disease Risk Assessment

open access: yesEnvironmental DNA, Volume 6, Issue 5, September–October 2024.
Environmental DNA (eDNA) isolated from multiple environmental sources were used to better assess location suitability for parasite and snail intermediate host species in agricultural settings. ABSTRACT Parasite transmission occurs in complex environments comprising multiple matrices.

Relação entre a patogenicidade de Schistosoma mansoni em camundongos e a susceptibilidade do molusco vetor: I. Infecciosidade das cercárias e carga de vermes Relationship between the pathogenicity of Schistosoma mansoni in mice and the susceptibility of the vector mollusc: I. Cercariae infectivity and worm burden

open access: yesRevista de Saúde Pública, 1991
Foram pesquisadas as possíveis influências que os mecanismos imunes do molusco poderiam exercer no desenvolvimento dos esporocistos e no comportamento do verme adulto no hospedeiro vertebrado. Utilizaram-se duas linhagens de S.

Different stressors uniquely affect the expression of endocannabinoid‐metabolizing enzymes in the central ring ganglia of Lymnaea stagnalis

open access: yesJournal of Neurochemistry, Volume 168, Issue 9, Page 2848-2867, September 2024.
The endocannabinoid system (ECS) modulates neuroprotection, energy balance, and stress and fear response. Invertebrate models like Lymnaea stagnalis shed a light on ECS's evolutionary conserved functions. In this study, ECS enzyme transcripts were identified and characterized in snail central nervous system, showing a high level of conservation with ...
