Abstract

The evolution of multicellular organisms was marked by adaptations to protect against pathogens. Themechanisms for discriminating the ’’self’’ from ’’non-self” have evolved into a long history of cellularand molecular strategies, from damage repair to the co-evolution of host-pathogen interactions. Weinvestigated the inflammatory response in Anemonia sulcata (Cnidaria: Anthozoa) following injection ofsubstances that varied in type and dimension, and observed clear, strong and specific reactions, especiallyafter injection of Escherichia coli and Vibrio alginolyticus. Moreover, we analyzed enzymatic activity of protease,phosphatase and esterase, showing how the injection of different bacterial strains alters theexpression of these enzymes and suggesting a correlation between the appearance of the inflammatoryreaction and the modification of enzymatic activities. Our study shows for the first time, a specific reactionand enzymatic responses following injection of bacteria in a cnidarian.
