Enhanced transcriptomic responses in the Pacific salmon louse Lepeophtheirus salmonis oncorhynchi to the non-native Atlantic Salmon Salmo salar suggests increased parasite fitness

Project description:This study investigates host-specific gene expression of the Pacific salmon lice, Lepeophtheirus salmonis oncorhynchii, while parasitizing a resistant host (Coho salmon), two susceptible hosts (Atlantic salmon, Sockeye salmon), and a population with-held hosts (starved), over 48 hrs.

Differentiating size-dependent responses of juvenile pink salmon (Oncorhynchus gorbuscha) to sea lice (Lepeophtheirus salmonis) infections

Project description:Salmon infected with an ectoparasitic marine copepod, the salmon louse Lepeophtheirus salmonis, incur a wide variety of consequences depending upon host sensitivity. Juvenile pink salmon (Oncorhynchus gorbuscha) migrate from natal freshwater systems to the ocean at a young age relative to other Pacific salmon, and require rapid development of appropriate defences against marine pathogens. We analyzed the early transcriptomic responses of naïve juvenile pink salmon of sizes 0.3g (no scales), 0.7g (mid-scale development) and 2.4g (scales fully developed) to a low-level laboratory exposure with early moult stage L. salmonis. All infected size groups exhibited unique transcriptional profiles. Inflammation and inhibition of cell proliferation was identified in the smallest size class (0.3g), while increased glucose absorption and retention was identified in the middle size class (0.7g). Tissue-remodelling genes were also up-regulated in both the 0.3g and 0.7g size groups. Profiles of the 2.4g size class indicated cell-mediated immunity and possibly parasite-induced growth augmentation. Understanding a size-based threshold of resistance to L. salmonis is important for fisheries management. This work characterizes molecular responses reflecting the gradual development of innate immunity to L. salmonis between the susceptible (0.3g) and refractory (2.4g) pink salmon size classes.

Sex-Biased Gene Expression and Sequence Conservation in Pacific and Atlantic Salmon Lice (Lepeophtheirus salmonis)

Project description:This study investigates sex-biased gene expression between populations of Atlantic and Pacific salmon lice, Lepeophtheirus salmonis. Two Atlantic L. salmonis populations were previously used for an array study (GSE56024) while a third dataset using Pacific L. salmonis was novel. Using all three populations, a consensus-based, meta-analysis approach was used to identify sex-biased and sex-specific genes.

Interacting effects of sea louse (Lepeophtheirus salmonis) infection and formalin-killed Aeromonas salmonicida in Atlantic salmon skin transcriptome

Project description:Lepeophtheirus salmonis (sea lice) and bacterial co-infection threatens wild and farmed Atlantic salmon performance and welfare. The present microarray-based study examined the dorsal skin transcriptome response to formalin-killed Aeromonas salmonicida bacterin (ASAL) in pre-adult sea lice-infected and non-infected Atlantic salmon to fill the existing knowledge gap and aid in developing anti-co-infection strategies. To this aim, sea lice-infected and non-infected salmon were intraperitoneally injected with either phosphate-buffered saline (PBS) or ASAL (i.e., 4 injection/infection groups: PBS/no lice, PBS/lice, ASAL/no lice, and ASAL/lice). The analysis of the dorsal skin transcriptome data [Significance Analysis of Microarrays (5% FDR)] identified 345 up-regulated and 2,189 down-regulated DEPs in the comparison PBS/lice vs. PBS/no lice, and 82 up-regulated and 3 down-regulated DEPs in the comparison ASAL/lice vs. ASAL/no lice. The comparison ASAL/lice vs. PBS/lice identified 272 up-regulated and 11 down-regulated DEPs, whereas ASAL/no lice vs. PBS/no lice revealed 27 up-regulated DEPs. The skin transcriptome differences between the co-stimulated salmon (i.e., ASAL/lice) and PBS/no lice salmon accounted for 1,878 up-regulated and 3,120 down-regulated DEPs.
