7.6 Genomic Approaches in Host–Pathogen Interaction
7.6.1 Host–Parasite Interactions in Fish
In intensively cultured fish species like the European sea bass, the gilthead
seabream, the Atlantic salmon or the Senegal sole, infections are more likely to
occur and may cause significant economic losses, either directly through pathogen-induced mortality, or indirectly through the impossibility of selling infected
animals. Most teleost pathogens, classified in viral, bacterial and parasitical, are
species-specific (Table 7.1).
