Differential expression of American lobster (Homarus americanus) immune related genes during infection of Aerococcus viridans var. homari, the causative agent of Gaffkemia

► First large-scale transcriptomic study undertaken for the American lobster. ► H. americanus immune response examined during an A. viridans bacterial infection. ► 148 differentially expressed genes identified in H. americanus immune response. ► Differential expression of six anti-lipopolysaccharide factor isoforms.
