英文摘要Rearing density and disease management are considered as pivotal factors determining shrimp farm productivity and profitability. To systematically investigate the potential mechanisms for density-related differences between disease susceptibility and rearing densities, we conducted comparative transcriptome analysis of the molecular differences between hepatopancreas and intestine of Litopenaeus vannamei under two different rearing densities (800- and 400- shrimp/m(3)) for 15 d and further analyzed the differences in immune response to Vibrio parahaemolyticus E1 (VPE1) raised under two density conditions. Totally 45 different expression genes (DEGs) were identified in the hepatopancreas under two different rearing densities, the DEGs were grouped into four processes or pathways related to animal immune system. Then, exposure to the VPE1 resulted in 639 DEGs, involved into fourteen immune related processes or pathways. In the intestine, seventeen processes or pathways related to the immune system were identified among the 5470 DEGs under two different rearing densities. 279 DEGs were identified post VPE1 challenge, classified into five processes or pathways associated with the immune system. Meanwhile, the results of growth performance, histopathology and the activities of antioxidant enzymes in the hepatopancreas and intestines of shrimp showed that high density decreased weight gain rate (63.20 +/- 1.67% and 18.73 +/- 3.35% in the high and low rearing density groups, respectively), severely destroyed the histopathology and inhibited the antioxidant enzymes activities. This study demonstrated that rearing density in L. vannamei significantly impacts susceptibility to the VPE1, via altered transcriptional challenge responses, and thus higher mortality due to disease.
