Yosra Ben Cheikh is a Lecturer and Researcher at the University of Le Havre, affiliated with the joint research unit UMR-I 02 SEBIO (Environmental Stress and BIOmonitoring of aquatic environments), which integrates the University of Le Havre, University of Reims Champagne-Ardenne, and INERIS. Her work centers on host-pathogen-environment interactions in marine bivalves, particularly the blue mussel (Mytilus edulis), investigating mortality events linked to Vibrio splendidus infections and contaminant impacts.
Her research integrates marine immunology and environmental toxicology to dissect how chemical stressors like benzophenone-3 compromise immune defenses in mollusks. Key methodologies include cellular motility assays, molecular characterization of efflux pumps (e.g., ABCG2), and microbiome analysis to identify non-invasive health biomarkers. Current projects like MICROTOOL leverage microbial signatures for ecosystem biosurveillance, reflecting her focus on translating laboratory findings to field applications.
Analysis of her 15 most recent publications reveals consistent emphasis on haemocyte motility as a quantitative immunotoxicity indicator, contaminant-pathogen synergy in bivalve mortality, and innovative microbiome-based monitoring tools. Her work spans fundamental mechanisms (eicosanoid signaling in inflammation) to applied solutions (biosurveillance protocols for port environments), establishing critical links between molecular responses and ecosystem health.
Dr. Ben Cheikh utilizes SEBIO's technical platforms including cell biology-cytometry, molecular microbiology, and experimental mesocosms (Mobicyte) for controlled stress exposure studies. Her research directly informs environmental risk assessment of emerging contaminants in coastal ecosystems through multidisciplinary approaches bridging immunology, toxicology, and microbial ecology.
