TL;DR: The present study evaluated the interactive effects of cadmium contamination and pathogenic organisms (trematodes Himasthla elongata and bacteria Vibrio tapetis) singularly and in combination during 7 days on the bivalve Cerastoderma edule to assess the health status of organisms.

TL;DR: Monitoring in two cockle and two Manila clam populations highlighted that the discrepancy between population health and stress levels could be due to insufficient response by bivalves and/or by unfavourable ecological factors.
42 citations
TL;DR: Sensitivity of Manila clams to both stressors differed from one site to another, suggesting local adaptation of populations, and it is important to be cautious when extrapolating results from field studies of one species and one site, if the life history of the organisms is not taken into account.
Abstract: Introduction
Within the last decade, numerous studies have investigated the role of environmental history on tolerance to stress of many organisms. This study aims to assess if Manila clams Ruditapes philippinarum may react differently to cadmium exposure and trematode parasite infection (Himasthla elongata) depending on their origin and environmental history in Arcachon Bay (France).

TL;DR: Results showed that infection by opportunistic pathogens affects metal accumulation, leading to maximal Cd accumulation in co-infected clams, highlighting the necessity of taking pathogens into account in ecotoxicological studies.

TL;DR: In Cd-exposed cockles, induction of Cemt1 is time-dependent following a "pulse-scheme" with significant upregulation at 24h and 168h intersected by time point (72h) with significant downregulation, indicating the presence of other effective cellular ligands which sequester the cytosolic fraction of this metal and consequently inhibit metal reactivity.
