Summary: To understand the interaction between shrimp and intestinal microbiota, multidisciplinary platforms were used to analyze the metagenome, transcriptome, and metabolome. The study found that exposure to Vibrio harveyi disrupted the bacterial communities in the shrimp intestine. Gene expression analysis revealed upregulation of immune-related pathways, while metabolomics analysis showed changes in lipid metabolism. The findings suggest the importance of lipid metabolism and the impact of pathogenic Vibrio on shrimp immunity. This study provides valuable insights into the host-gut microbial relationship and its influence on shrimp innate immunity.

Summary: In this study, a novel TRIM37 homolog called PmTRIM37 was identified, which plays important roles in regulating innate immune processes, particularly antiviral and proinflammatory cytokine responses. PmTRIM37 is highly expressed in immune-related tissues and its expression is up-regulated after white spot syndrome virus (WSSV) infection. Knockdown of PmTRIM37 promotes WSSV replication and VP28 expression, suggesting its negative role in WSSV infection. Furthermore, PmTRIM37 positively regulates the NF-κB pathway and Antimicrobial peptides (AMP) expression during WSSV infection.

Summary: In this study, a fibrinogen-related protein in the black tiger shrimp Penaeus monodon was identified and characterized. The PmFreP was found to be mainly expressed in the intestine, able to bind bacteria and facilitate the clearance of pathogens in shrimp innate immunity. These results suggest that PmFreP may serve as pattern recognition receptors implicated in shrimp innate immunity.

Summary: This study identified and characterized novel miRNAs in virus-free disease-resistant and disease-susceptible Penaeus monodon, revealing a large number of known and new miRNAs in both samples. The differential expression study showed up-regulated and down-regulated miRNAs in disease-resistant and disease-susceptible P. monodon, suggesting a potential and specific role of P. monodon miRNAs in signal transduction, cell-to-cell signaling, innate immune response, and defense response to different pathogens.

Summary: The qnrVv gene in Vibrio vulnificus plays a role in resistance to antibiotics and cold shock response; qnrVv and cspA genes may have significant functions in the organism's response to different environmental conditions and stresses, with more pronounced effects observed in a double mutant.

Summary: This study cloned the Grx3 of Penaeus monodon (PmGrx3) and revealed its basic information and distribution in the organism, as well as its expression patterns. The results suggest that PmGrx3 may play an important role in shrimp's resistance against environmental stress and pathogen infection.

Summary: The study cloned a MAPKK cDNA from black tiger shrimp and found that it plays a crucial role in stress resistance and immunity. The expression of PmMAPKK was highest in the ovary and varied in different tissues and developmental stages. In bacterial infection and low-salinity stress experiments, PmMAPKK expression levels were significantly altered, affecting the mortality rate of shrimp under stress conditions. The activation of ERK, JNK, and p38 signaling pathways suggested complex regulatory mechanisms in the MAPK signaling pathway. These results indicate the involvement of PmMAPKK in the innate immune mechanism of P. monodon and its adaptation to low-salinity environments.

Summary: The research identified a novel TRIM32 homolog, PmTRIM32, in Penaeus monodon, which was significantly upregulated by rapamycin stimulation and WSSV infection. PmTRIM32 was found to restrict WSSV replication, positively regulate autophagy and NF-kappa B pathway, and interact with WSSV envelope protein for ubiquitination.

Summary: This study investigated the distribution of Vibrio spp. in cultured shrimp in different regions of Peninsular Malaysia. Out of the 225 isolates examined, 13 Vibrio spp. were identified and characterized. The virulence genes and pathogenicity of V. parahaemolyticus S12-3 towards P. monodon were demonstrated, highlighting the importance of microbiological risk assessments for shrimp farming.

Summary: TRIM9 plays a crucial role in regulating innate immune signaling. The identification of a novel TRIM9 homolog (PmTRIM9) in Penaeus monodon revealed its involvement in facilitating V. parahaemolyticus infection by negatively regulating the PmRelish-mediated expression of antimicrobial peptides.

Summary: The study found that the immune system of the half-smooth tongue sole is not sensitive to moderate- or low-dose Vibrio vulnificus infection, while leukocytes, ALP, and complement primarily play a role in resisting high-dose infection. A variety of intestinal microbial taxa are important in inhibiting Vibrio vulnificus growth.

Summary: The study showed that the pathogens VP and WSSV significantly reduced hemocyte counts and increased glucose and serotonin levels in the hemolymph of black tiger shrimp. These pathogenic treatments altered the expression pattern of candidate genes and affected the physiological and biochemical parameters, resulting in negative impacts on growth and mortality of the experimental shrimps.
