Coelomic fluid lysozyme activity induction in the polychaete Eurythoe complanata as a biomarker of heavy metal toxicity

Description
Summary:In recent years there has been increasing concern over the potential deleterious effects of contaminated marine sediments on the biota. Polychaete annelids have been widely recognized as useful sentinels of varying degrees of benthic pollution as they constitute the most abundant number of species and specimens in subtidal marine soft-bottoms. This paper is aimed at the development of a toxicity test based on coelomic lysozyme measurements for the tropical cosmopolitan polychaete species Eurythoe complanata, using copper as a reference contaminant. Considering that lysozyme induction by bacterial inocculation could be sensitive to xenobiotics, it was taken as a sublethal endpoint for testing immunotoxic effects of copper on this organism.
