  • Environmental microbiomes drive chemotactile sensation in octopus.

    Rebecka J Sepela, Hao Jiang, Yern-Hyerk Shin 他 · Cell · 2025

    Microbial communities coat nearly every surface in the environment and have co-existed with animals throughout evolution. Whether animals exploit omnipresent microbial cues to navigate their surroundings is not well understood. Octopuses use "taste-by-touch" chemotactile receptors (CRs) to explore the seafloor, but how they distinguish meaningful surfaces from the rocks and crevices they encounter…

  • Multispecies individuals.

    Pierrick Bourrat, Paul E Griffiths · History and philosophy of the life sciences · 2018

    We assess the arguments for recognising functionally integrated multispecies consortia as genuine biological individuals, including cases of so-called 'holobionts'. We provide two examples in which the same core biochemical processes that sustain life are distributed across a consortium of individuals of different species. Although the same chemistry features in both examples, proponents of the ho…

  • Microbial diversity of garden snail mucus.

    Mihaela Belouhova, Elmira Daskalova, Ivaylo Yotinov 他 · MicrobiologyOpen · 2022

    The search for new natural compounds for application in medicine and cosmetics is a trend in biotechnology. One of the sources of such active compounds is the snail mucus. Snail physiology and the biological activity of their fluids (especially the mucus) are still poorly studied. Only a few previous studies explored the relationship between snails and their microbiome. The present study was focus…

  • Global biogeography of chemosynthetic symbionts reveals both localized and globally distributed symbiont groups.

    Jay T Osvatic, Laetitia G E Wilkins, Lukas Leibrecht 他 · Proceedings of the National Academy of Sciences of the United States of America · 2021

    In the ocean, most hosts acquire their symbionts from the environment. Due to the immense spatial scales involved, our understanding of the biogeography of hosts and symbionts in marine systems is patchy, although this knowledge is essential for understanding fundamental aspects of symbiosis such as host-symbiont specificity and evolution. Lucinidae is the most species-rich and widely distributed …

  • Chemoautotrophy, symbiosis and sedimented diatoms support high biomass of benthic molluscs in the Namibian shelf.

    K Amorim, N Loick-Wilde, B Yuen 他 · Scientific reports · 2022

    The molluscs Lucinoma capensis, Lembulus bicuspidatus and Nassarius vinctus are highly abundant in Namibian oxygen minimum zone sediments. To understand which nutritional strategies allow them to reach such impressive abundances in this extreme habitat we investigated their trophic diversity, including a chemosymbiosis in L. capensis, focussing on nitrogen biochemical pathways of the symbionts. We…

  • Geographical and temporal variation of E. coli and norovirus in mussels.

    S Strubbia, B P Lyons, R J Lee 他 · Marine pollution bulletin · 2016

    Bivalve shellfish may accumulate contaminants of public health concern including pathogenic bacteria and viruses. Microbiological monitoring of production areas is based on faecal coliforms in water in the USA and Escherichia coli in bivalve molluscs in the European Union. E. coli is known to reflect contamination with Salmonella enterica but not necessarily with other human pathogens such as ente…

  • Bioaccumulation and toxicological effects of dietborne arsenic exposure on the apple snail (Pomacea canaliculata).

    Xiaoyang Bi, Yanwei Liu, Yan Wang 他 · Journal of hazardous materials · 2024

    An eight-compartment physiologically based pharmacokinetic (PBPK) model was used to simulate the bioaccumulation and distribution of arsenic (As) within the apple snail (Pomacea canaliculata) following the ingestion of As-contaminated lettuce. The bioaccumulation results revealed that the shell contained the majority (67.21 %) of the total As content, with the liver and the head-foot containing ap…

  • Pseudoalteromonas bacteria are capable of degrading paralytic shellfish toxins.

    Carrie J Donovan, Rafael A Garduño, Martin Kalmokoff 他 · Applied and environmental microbiology · 2009

    Marine bacterial isolates cultured from the digestive tracts of blue mussels (Mytilus edulis) contaminated with paralytic shellfish toxins (PSTs) were screened for the ability to reduce the toxicity of a PST mixture. Seven isolates reduced the overall toxicity of the algal extract by > or = 90% within 3 days. These isolates shared at least 99% 16S rRNA gene sequence similarity with five Pseudoalte…

  • Microbiome response differs among selected lines of Sydney rock oysters to ocean warming and acidification.

    Elliot Scanes, Laura M Parker, Justin R Seymour 他 · FEMS microbiology ecology · 2021

    Oyster microbiomes are integral to healthy function and can be altered by climate change conditions. Genetic variation among oysters is known to influence the response of oysters to climate change and may ameliorate any adverse effects on oyster microbiome; however, this remains unstudied. Nine full-sibling selected breeding lines of the Sydney rock oyster (Saccostrea glomerata) were exposed to pr…

  • Detection of Hepatitis E Virus in Shellfish Harvesting Areas from Galicia (Northwestern Spain).

    Enrique Rivadulla, Miguel F Varela, João R Mesquita 他 · Viruses · 2019

    The hepatitis E virus (HEV) affects almost 20 million individuals annually, causing approximately 3.3 million acute liver injuries, 56,600 deaths, and huge healthcare-associated economic losses. Shellfish produced close to urban and livestock areas can bioaccumulate this virus and transmit it to the human population. The aim of this study was to evaluate the presence of HEV in molluscan shellfish,…
