Summary: This study investigated the impact of Vibrio alginolyticus on the intestinal histomorphology and microbiome composition in Litopenaeus vannamei. The results showed that Vibrio alginolyticus infection caused exfoliation of intestinal mucosal epithelial cells and altered the tissue morphology of the intestine. It also affected the abundance and diversity of intestinal microbiome.

Summary: This study investigates the role of bacterial flagella in the invasion of host organisms and the activation of the immune system in shrimp. The results show that the flagella of Vibrio alginolyticus play a crucial role in shrimp infection, and the C-type lectins and TRAF6 gene are involved in flagella recognition and immune system activation. This research provides insights into the mechanisms of shrimp immunity and could contribute to the development of strategies to combat bacterial infections in shrimp farming.

Summary: In this study, the transcriptomic profiles of Litopenaeus vannamei hepatopancreas and the morphological changes were investigated by injecting with bacterial extracellular products or V. alginolyticus. The transcriptome data revealed differential expression genes related to lysosome pathway, glycerophospholipid metabolism, and lipid metabolism. The findings showed that V. alginolyticus utilized lipids from L. vannamei as a nutrient source and modulated lipid homeostasis to determine the fate of infection.

Summary: In this study, the effect of Andr on the growth, immunity, and resistance to V. alginolyticus infection in L. vannamei was investigated. The results showed that dietary Andr improved the growth performance and non-specific immune function of shrimps. Furthermore, Andr protected shrimps against V. alginolyticus by regulating inflammation and apoptosis via a ROS-JNK dependent pathway.

Summary: The study investigated the role of Tyramine beta-hydroxylase (TBH) in white shrimp, Litopenaeus vannamei, under hypothermal stress and Vibrio alginolyticus infection. It was found that LvTBH gene expression was upregulated, leading to increased release of octopamine (OA).

Summary: In Litopenaeus vannamei, the cloned LvTDC gene is responsible for the synthesis of octopamine, regulating physiological and immune responses. Knockdown of LvTDC resulted in significant decreases in immune function and physiological parameters, indicating the crucial role of LvTDC in maintaining homeostasis in shrimp.LvTDC knockdown shrimp also showed reduced survival rates in a Vibrio alginolyticus challenge test compared to control groups.

Summary: In this study, the impact of Clostridium butyricum feeding on intestinal microorganisms and protection against Vibrio alginolyticus infection in Penaeus vannamei was evaluated. The results showed that Clostridium butyricum significantly altered the abundance of intestinal microbial populations and reduced Vibrio spp. Furthermore, the Clostridium butyricum-fed group exhibited improved survival rate, reduced pathological changes, and enhanced immune response against V. alginolyticus infection compared to the control group.

Summary: In this study, a novel C-type lectin (CTL) called perlucin-like protein (PLP) was identified in Litopenaeus vannamei. PLP could be activated in response to Vibrio harveyi infection and could bind and agglutinate various bacteria. PLP was involved in stabilizing the expression of immune-related and apoptosis genes and reducing bacterial load in the hepatopancreas.

Summary: This study compared the transcriptome of Litopenaeus vannamei Zoea larvae and adults infected by Vibrio parahaemolyticus using high-throughput Illumina sequencing. The results showed that pathways involved in the innate immune response were more enriched in the Zoea stage compared to the adult stage, suggesting the existence of innate immunity against Vibrio vulnificus during the Zoea larvae stage. These findings provide useful information for the study of innate immunity in shrimp larvae.

Summary: NF-E2-related factor-like-2 (Nrf2), a transcription factor belonging to the Cap'n'Collar transcription factor family, plays a role in regulating inflammation, autophagy, metabolism, proteostasis, and cancer prevention. The effects of Nrf2 on the immune response in Vibrio spp infection were investigated. The results showed that Nrf2 RNAi decreased antioxidant-related genes expression and up-regulated inflammation-related genes and apoptosis gene. Histopathological analysis revealed tissue damage in Nrf2 RNAi group, while SFN group exhibited lessened tissue damage and fewer apoptosis signals.
