Diet of schistosome vectors influences infection outcomes

Ecosphere, 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

Environmental 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.

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

Journal 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 ...

Estratégia competitiva entre Biomphalaria glabrata e Biomphalaria tenagophila: estudos de laboratório [PDF]

Memórias do Instituto Oswaldo Cruz, 1989
Observation about conhabitation among B. glabrata and B. tenagophila revealed a greater vulnerability of B. tenagophila population during the process of competition when its density was severaly decreased in 12 trials, moderate in 2 trials. It was higher than B. glabrata in only one trial.

Trained immunity: Perspectives for disease control strategy in marine mollusc aquaculture

Reviews in Aquaculture, Volume 16, Issue 4, Page 1472-1498, September 2024.
Abstract Recent evidence has demonstrated the unique properties of the innate immune system, known as innate immune memory, immune priming, or trained immunity. These properties have been described as the ability of the innate immune system to learn from previous microbial experiences, which improves survival after subsequent infection. In this review,

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

Revista 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.

Invasive freshwater snails are less sensitive to population density than native conspecifics

Ecology and Evolution, Volume 14, Issue 5, May 2024.
Species invasion can negatively affect natural ecosystems, so understanding how and why lineages become invasive is critically important to effectively predict potential future invasions. We address whether key life‐history traits across invasive versus native lineages of a New Zealand freshwater snail species differ in response to population density ...

Estudo da suscetibilidade da Biomphalaria glabrata de Ourinhos (SP), à infecção pelo Schistosoma mansoni de Belo Horizonte (MG), e de São José dos Campos (SP) Susceptibility of Biomphalaria glabrata from Ourinhos, SP to schistosomiasis infection by Schistosoma mansoni strain from Belo Horizonte, MG and S. José dos Campos, SP (Brazil)

Revista de Saúde Pública, 1973
Foi estudada a suscetibilidade da Biomphalaria glabrata de um foco de Schistosoma mansoni no município de Ourinhos, (SP, Brasil). Concluiu-se pela alta capacidade desses moluscos à infecção pelas cepas de S.

Procambarus virginalis Lyko, 2017: A new threat to Iberian inland waters

Ecology and Evolution, Volume 14, Issue 5, May 2024.
We provide the first record of Procambarus virginalis in the Iberian Peninsula, based on morphological and genetic evidence (molecular barcoding of COI). We discuss its most plausible introduction pathways, update its global geographical distribution, highlight the potential impacts if it becomes invasive in Iberia and recommend some proposal ...

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.
