The Atlantic salmon (Salmo salar) antimicrobial peptide cathelicidin-2 is a molecular host-associated cue for the salmon louse (Lepeophtheirus salmonis) Gustavo Núñez-Acuña, Cristian Gallardo-Escárate, David M. Fields, Steven Shema, Anne Berit Skiftesvik, Ignacio Ormazábal & Howard I. Browman Chemical signals are a key element of host-parasite interactions. In marine ecosystems, obligate ectoparasites, such as sea lice, use chemical cues and other sensory signals to increase the probability of encountering a host and to identify appropriate hosts on which they depend to complete their life cycle.
