Abstract
This review aims to provide an update on the current scientific understanding of various aspects of White Spot Syndrome Virus (WSSV) formation, diagnostic procedures, transmission, ecological effects, pathophysiology and management strategies. In terms of production and financial benefits, the WSSV has been the most virulent in shrimp and several other crustacean sectors around the globe. It spreads vertically from diseased broodstock to post-larvae and horizontally by cannibalism, invertebrate vectors, freshwater and sediments. In the transfer of white spot disease (WSD) in newly stocked ponds, the survivability of WSSV in sediment is the most important variable. In typical cultural conditions, it is a highly infectious pathogen capable of inflicting total death within 3-10 days after an outbreak. Some of the current biosecurity strategies used to keep diseases out of shrimp ponds such as pond water disinfection, quarantine of new stocks before stocking and broader usage of specific pathogen-free shrimp. The sequencing and characterisation of various WSSV strains have provided details about pathogen biology, pathogenicity and disease. To develop successful control methods, knowledge of these characteristics is essential. In several shrimp-producing countries in Asia and the Americas, the infections produced by the WSSV have had disastrous socio-economic consequences. As a result of international trade or migration of diseased species, the World Animal Health Organization recognised several illnesses as posing a substantial hazard to farmed shrimp. WSD is receiving much scientific research due to the potential economic effects of the virus. Research is now being done to understand better the molecular biology and pathophysiology of WSSV, as well as how to treat and prevent the virus. However, further study should be conducted in countries with more resilient host species to understand their role in mitigating disease impacts since these revelations may aid in developing a WSD treatment.

Abstract
Severe fever with thrombocytopenia syndrome virus (SFTSV) is a newly emerging tick-borne virus with a case fatality rate between 12% and 50%. Currently, effective vaccines or antiviral drugs are not available, and a diagnostic method for detecting SFTSV is urgently needed. The monoclonal (MAb) and polyclonal antibodies (PAb) against SFTSV were prepared by immunizing animals with SFTSV nucleocapsid protein (NP), and using both monoclonal and polyclonal antibodies as capture antibodies against NP, we developed two different double-antibody sandwich enzyme-linked immunosorbent assays (DAS-ELISAs) for detecting the NP of SFTSV. Both methods were applicable for the diagnosis of SFTSV-infected patients, as confirmed by quantitative polymerase chain reaction. Furthermore, the sensitivity and specificity of two assays for diagnosing SFTS were both 100%, and had no reaction to recombinant Dabieshan NP or recombinant Dengue virus NS1 subtype 1 and 2 proteins. In addition, two standard curves were established for quantitative detection of the NP, and the monoclonal antibody-based ELISA (MAb-based ELISA) test had a lower limit of detection than the polyclonal-based ELISA (PAb-based ELISA) test. Therefore, the MAb-based ELISA could be employed for detecting SFTSV in a convenient and effective way.

The feeding of dietary Codonopsis pilosula polysaccharide enhances the immune responses, the expression of immune-related genes and the growth performance of red swamp crayfish (Procambarus clarkii). FISH & SHELLFISH IMMUNOLOGY 2020; 103:321-331. [PMID: 32446966 DOI: 10.1016/j.fsi.2020.05.034] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Revised: 05/11/2020] [Accepted: 05/12/2020] [Indexed: 06/11/2023]
Abstract
Polysaccharides have many functions in aquatic animals and are widely used as immunopotentiators. However, despite the emergence of serious diseases, few studies have explored the effects of Codonopsis pilosula polysaccharide (CPP) on crustaceans. We studied the effects of CPP on the growth performance, nonspecific immunity, antioxidant activity and disease resistance of red swamp crayfish (Procambarus clarkii). Healthy crayfish (5.80 ± 0.1 g) were fed diets supplemented with 0% (control), 0.05%, 0.1%, 0.15%, 0.20%, and 0.30% CPP for 8 weeks. At the end of the 8-week feeding trial, the optimal final body weight (FBW), weight gain (WG), specific growth rate (SGR), and feed conversion ratio (FCR) were observed in the crayfish fed the diets with 0.15% and 0.20% CPP, followed by those fed the diet with 0.30% CPP and then those fed the diet with 0.10% CPP, whereas the values of these parameters were obtained with the control crayfish (P < 0.05). The crayfish fed the diets with 0.15% and 0.20% CPP exhibited a significantly higher total hemocyte count (THC) and significantly increased phenoloxidase (PO), lysozyme (LZM), hemocyte (Hc), acid phosphatase (ACP) and alkaline phosphatase (AKP) compared with those belonging to the other groups (P < 0.05). The crayfish fed the diets with 0.15% and 0.2% CPP exhibited significantly higher total superoxide dismutase (T-SOD) and glutathione peroxidase (GPx) activities, a significantly increased total antioxidant capacity (T-AOC) and a significantly lower malondialdehyde (MDA) content compared with the other groups (P < 0.05), which indicated that antioxidant capacity was significantly induced by the CPP-supplemented diets. Significantly upregulated expression of immune-related genes (anti-lipopolysaccharide factors (alf), peroxiredoxin (prx5), cathepsin B (ctsb), mitochondrial manganese superoxide dismutase (mtMnsod), cyclophilin A (cypa), glutathione peroxidase (gpx), Toll-like receptor 3 (tlr3), and heat shock protein 70 (hsp70)) was detected in the crayfish fed the diets supplemented with 0.15% and 0.20% CPP diet compared with the levels observed in the control crayfish. These results showed that dietary CPP supplementation greatly improved the growth, immunity and antioxidant capacities of crayfish, and according to the observed results, 0.15%-0.2% is the recommended optimal level of CPP dietary supplementation for crayfish.

Abstract
Vibrio harveyi is one of the pathogens that threaten the shrimp farming industry. However, metabolic changes induced by V. harveyi infection in shrimp remain unknown. In this study, we first conducted high resolution-magic angle spinning (HR-MAS) nuclear magnetic resonance (NMR)-based metabolomics studies on gill, hepatopancreas, and haemolymph of V. harveyi-infected white leg shrimp, Litopenaeus vannamei. Using multivariate statistical analysis, we observed a clear separation between the early (3 and 9 h post-injection (hpi)) and late phases (24, 72 and 144 hpi) of the infection in all tissues. Moreover, metabolic changes in response to V. harveyi infection were faster in the haemolymph in the early phase and significantly changed in the late phase of the infection in the gills. Extensive changes were observed in the hepatopancreas, with 24 hpi being the turning point of progression from early to late phase infection in the hepatopancreas. V. harveyi infection increased the energy demand in L. vannamei and the amino acid and carbohydrate metabolism pathways also exhibited significant changes depending on the tissue. Thus, each tissue displayed different metabolic changes, depending on the progress of the infection.

Abstract
Hemocyanin is a respiratory protein that possesses multiple physiological and immunological functions in shrimp. However, the transcriptional regulation of the hemocyanin gene is still poorly understood. Here, the nuclear receptor E75 of Litopenaeus vannamei (LvE75) was identified as one of the transcriptional regulators that modulates the transcription of the small molecular weight hemocyanin gene of L. vannamei (LvHMCs) by inhibiting its core promoter activity in a Dual-luciferase assay. In silico analysis revealed that the core promoter (designated HsP3), which is located at +1517/+1849 bp of LvHMCs contained a putative E75 binding motif ("ACGGAAT", spanning +1812/+1818 bp). Further, LvE75 was shown to inhibit the core promoter activity by direct binding. Importantly, in vivo silencing of LvE75 resulted in a significant upregulation in the mRNA and protein expression of LvHMCs gene. Taken together, our present results provide direct evidence that LvE75 is a transcriptional suppressor of the LvHMCs gene expression.

Abstract
Taurine has been widely researched as a growth-promoting additive or as an antioxidant in aquatic animals because of its multiple functions, however, few studies have explored its effects on crustacean in spite of the occurrence of serious diseases. We studied the effects of taurine supplementation on the growth, non-specific immunity, anti-oxidative properties and gut immunity of the Chinese mitten crab Eriocheir sinensis. Healthy crabs (8.0 ± 0.5 g) were fed diets supplemented with taurine at 0% (control), 0.2%, 0.4%, 0.8%, and 1.6% for 65 days. At the end of this 65 days feeding trial, the final weight, weight gain, specific growth rate, and feed conversion ratio were best in crabs fed the 0.4% taurine diet, followed by that in those fed the 0.8% taurine diet; the parameters were worst for the control group. Carapace length (CL) and carapace width (CW) were significantly increased in the crab fed the 0.4% and 0.8% taurine diet than that of the other three groups. Total haemocyte count (THC) and acid phosphatase (ACP) activity were significantly higher in the crab fed the 0.8% taurine diet than in those belonging to the other groups, the crabs fed the 0.4% taurine diet had the highest phenoloxidase (PO), lysozyme (LZM), and alkaline phosphatase (AKP) activities, however, there was no obvious change in their haemocyanin (Hc) content. According to superoxide dismutase (SOD), glutathione Peroxidase (GSH-PX), total anti-oxidant capacity (T-AOC) activities and malondialdehyde (MDA) content, the antioxidant capacity was significantly induced by taurine diet, while was higher in crabs fed 0.4 %-0.8% taurine diet than that of the other groups. Taurine supplementation significantly up-regulated the expression of gut immune genes (EsToll2, EsRelish) and antimicrobial peptides (EsALF1, EsALF2, EsCrus1, EsCrus2) in crabs gut fed the 0.2-0.8% taurine diet group compared to control. Thus, these study results indicate that dietary taurine is important for improving growth, regulating immunity, and enhancing the antioxidant capacity in crabs, with the recommended optimum dietary allowance being 0.4 %-0.8% taurine for E. sinensis.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2018; 84:371-381.

Abstract
Acute hepatopancreatic necrosis disease, AHPND, caused by a specific strain of Vibrio parahaemolyticus (VPAHPND), results in great loss of global shrimp production. Despite this, studies on shrimp defense mechanisms protecting against AHPND are few. In this study, suppression subtractive hybridization (SSH) was performed to identify differentially expressed genes from white shrimp Litopenaeus vannamei hepatopancreas upon VPAHPND infection at the early stages: 3 and 6 h post challenge and in the late stage at 48 h post challenge. Hemocyanin (HMC) is the most abundant gene identified as the up-regulated gene in the SSH library. Various hemocyanin subunits such as hemocyanin (HMC), hemocyanin subunit L1 (HMCL1), L2 (HMCL2), L3 (HMCL3), and L4 (HMCL4) were analyzed for their expression levels upon VPAHPND infection and in response to challenge with partially purified toxin of VPAHPND by qRT-PCR. Only HMC was highly up-regulated at 3 and 6 h post challenge in response to VPAHPND challenge. Two HMC subunits, HMCL3 and HMCL4, were up-regulated in the early phase of VPAHPND toxin injection. Furthermore, all subunits were down-regulated in the late phase of VPAHPND and toxin challenges. The native hemocyanin protein purified from shrimp hemolymph, identified as mixture of HMC and HMCL1, exhibited agglutination activity on VPAHPND. Injecting the purified native hemocyanin along with VPAHPND into shrimp decreased the number of bacteria in the hemolymph as compared to the VPAHPND challenged control. Moreover, pre-incubation of the purified native hemocyanin and VPAHPND toxin prior to injection into shrimp resulted in the decrease of cumulative mortality of shrimp when compared to the control. In addition, protein-protein interaction analysis carried out by ELISA technique indicated that hemocyanin exhibited VPAHPND toxin-neutralizing activity through direct interaction with PirA subunit with a dissociation constant of 6.83 × 10-6 M. Our results indicated that upon VPAHPND infection the expression of hemocyanin was induced and hemocyanin functions might involve agglutination of invading VPAHPND and also neutralization of VPAHPND secreted toxin via direct interacting with the PirA protein.

Abstract
Hemocyanins (HMC): the copper-containing respiratory proteins present in invertebrate hemolymph, which plays many essential roles in the immune system. Currently, little is known about the HMC domains of Procambarus clarkii (P. clarkii) and their function in antimicrobial immune response. In this present study, we comparatively studied the expression pattern of native PcHMC with the three recombinant proteins of variable domains of crayfish hemocyanin (PcHMC-N, N-terminal domain of hemocyanin; PcHMC-T, tyrosinase domain of hemocyanin; PcHMC-C, C-terminal domain of hemocyanin). The results showed that three purified recombinant proteins had a strong binding to various bacteria and lipopolysaccharides that further highly agglutinated. The HMCs recombinant proteins showed strong antibacterial activity against V. parahaemolyticus and S. aureus by bacterial growth inhibition, phenoloxidase (PO) and phagocytosis assays. Specifically, rPcHMC1-T and rPcHMC1-C inhibited both the bacteria efficiently, rPcHMC1-T was highly upregulated the PO activity than the other recombinant proteins. Whereas, recombinant proteins pretreated crayfish hemocytes participated in phagocytosis activity, rPcHMC1-N and rPcHMC1-C proteins had a profound effect than the rPcHMC1-T on S. aureus and V. parahaemolyticus phagocytosis. The crayfish hemocyanin domains clearly exhibited antibacterial and phagocytic activities against both the bacteria, suggesting that its variable domains of hemocyanin have the different function on specific pathogen during the assault of pathogens.

Abstract
Developing a rapid, accurate and quantitative method for detecting white spot syndrome virus (WSSV) is extremely urgent and critical for reducing the risk of white spot disease outbreaks. In the present work, an optimized double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was developed for quantitative detection of WSSV. The method employed rabbit polyclonal antibodies against WSSV as the capture antibody and previously produced anti-WSSV monoclonal antibodies as the detector antibody. A standard curve of the log concentration of WSSV versus OD value was established, which was linear in the concentration range of 120-7680ng/mL, and the linear regression equation was y=0.166x-0.151. Viral proteins in different tissues of crayfish (Procambarus clarkia) post artificial infection with WSSV were quantitatively measured using the DAS-ELISA. WSSV proliferated quickly within 60h post infection and gradually slowed down afterwards. According to the linear regression relationship, the viral proteins in hemolymph, gut and gonad were firstly able to be quantified at 24h post infection with the concentrations of 186, 158 and 128ng/mL, respectively. These three tissues also contained higher viral proteins than the gill, heart, hepatopancreas and muscle during the entire infection period. The viral protein concentration in gut reached the highest level of 6220ng/mL at 72h post infection. Real time quantitative PCR was also used to detect the dynamic change of viral copies in crayfish hemolymph post WSSV infection, with similar results for both assays. The developed DAS-ELISA could detect WSSV propagation from initial to moribund stage in infected crayfish and demonstrated potential application for diagnosis of WSSV.
