An infection of Ruditapes decussatus (Bivalvia) by Rickettsia [PDF]

Aquaculture, 1987
The authors report the presence of a Rickettsia in Ruditapes decussatus from natural populations of the Algarve (Portugal). Light microscopic shows infections of varying importance in gill tissues. Some enclose small procaryotic colonies (cp) scattered in all lamellae; in others, the colonies are scarce and hypertrophic (100 mu m).

Pre-induction of Hsp70 expression to protect the grooved carpet shell clam, Ruditapes decussatus, against Micrococcus luteus: A trained immunity strategy

Egyptian Journal of Aquatic Research, 2020
Bacterial pathogens cause disease-associated mortality in Ruditapes decussatus, a model bivalve for aquaculture in Egypt. In this study, it was hypothesized that trained immunity could be achieved to enhance disease resistance against Micrococcus luteus ...

Isolation and characterisation of metallothionein from the clam Ruditapes decussatus [PDF]

Aquatic Toxicology, 2003
Metallothioneins (MT) were obtained after purification from metal-exposed clams (Ruditapes decussatus) using gel-permeation and ion-exchange chromatography. Four cadmium-metallothioneins (CdMTs) were resolved by ion-exchange chromatography and they all had similar molecular weights, high cadmium content and an absorption spectra indicative of the ...

Ubiquitination and carbonylation as markers of oxidative-stress in Ruditapes decussatus [PDF]

Marine Environmental Research, 2008
Environmental pollutants, such as metals, are widespread in aquatic environments and can lead to the formation of reactive oxygen species (ROS). ROS are highly toxic in marine species since they can cause serious reversible and irreversible changes in proteins including ubiquitination and modifications such as carbonylation. This study aimed to confirm

Organic Phases in Bivalve (Arctica Islandica) Shells: Their Bulk and Amino Acid Nitrogen Stable Isotope Compositions

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 10, October 2023., 2023
Abstract The stable nitrogen isotope composition of bivalve shell organics serves as a proxy for nitrogen fluxes in modern and past ecosystems. An essential prerequisite to reconstruct environmental variables from δ15N values of bivalve shells is to understand if pristine isotope signals can be retrieved from shell organics after sample pretreatment ...

Energy regimes help tackle limitations with the prehistoric cultural‐phases approach to learn about sustainable transitions: Archaeological evidence from northern Spain

Journal of Quaternary Science, Volume 38, Issue 6, Page 921-937, August 2023., 2023
ABSTRACT Human societies face challenges in transitioning towards low‐carbon economies and sustainable management of land use and natural resources. Documenting and learning from past transitions helps policy‐makers cope with such challenges. The agricultural revolution in Cantabrian Spain (ca.

Reproduction Under Stress: Acute Effect of Low Salinities and Heat Waves on Reproductive Cycle of Four Ecologically and Commercially Important Bivalves

Frontiers in Marine Science, 2021
The impacts of climate change on the structure and functioning of estuaries is a major focus of concern, even more when the affected species support important fisheries as the bivalves Ruditapes decussatus, Ruditapes philippinarum, Venerupis corrugata ...

Uncovering the immunological repertoire of the carpet shell clam Ruditapes decussatus through a transcriptomic-based approach

Aquaculture and Fisheries, 2019
The grooved carpet-shell clam Ruditapes decussatus is native to the Northern Atlantic and Mediterranean Sea and has a high commercial value. It is one of the main native bivalve species cultured in Europe.

Biomarkers inRuditapes decussatus: a potential bioindicator species

Biomarkers, 2004
The clam Ruditapes decussatus is distributed worldwide and due to its ecological and economical interest has been proposed as a bioindicator in areas where mussels are not available. The accumulation of several anthropogenic compounds in their tissues suggests that they possess mechanisms that allow them to cope with the toxic effects of these ...
