Li Y, Li L, Miao W, Li X. Microbiome and transcriptome analyses reveal the influence of calcined dolomite application on Eriocheir sinensis in a rice-crab co-culture system. Sci Rep 2023; 13:17932. [PMID: 37864065 PMCID: PMC10589332 DOI: 10.1038/s41598-023-39099-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 07/20/2023] [Indexed: 10/22/2023] Open
Abstract
Co-culture systems of rice and aquatic animals can contribute to the ecological intensification of agriculture by reducing nutrient loss and the need for N fertilizer application and by enhancing nutrient-use efficiency. However, the input of high-protein diets into paddy fields, to facilitate the growth of aquatic animals, has been found to increase N pollution and acidification of the soil. Although soil amendments have been widely used to ameliorate acidic soils, reduce N2O emissions, and improve agronomic production, the relationship between soil amendments and aquatic animal remains unclear. Therefore, this study investigated the effects of calcined dolomite (hereafter referred to as dolomite) as an acidic soil amendment and Ca-Mg supplement in rice-crab co-culture using Eriocheir sinensis crabs (Chinese mitten crabs). High-throughput sequencing was used to examine crab bacterial community composition and crab hepatopancreas biology. Although the water pH was significantly increased in the dolomite group, the number, composition, and diversity of bacteria identified in crab gut microbiome did not vary significantly between the dolomite and control groups. In the dolomite group, the probiotic agents Candidatus Hepatoplasma and Lactobacillus were highly abundant in the crab gut, and immune- and retinol metabolism-related genes were significantly upregulated in the crab hepatopancreas. Overall, dolomite application increased crab health and water pH. Dolomite is a low-cost amendment, with better stability, compared to other soil amendments, thus making it ideal for sustainable and clean rice-aquatic animal co-culture.

Transcriptome analysis of Macrobrachium rosenbergii hemocytes reveals in-depth insights into the immune response to Vibrio parahaemolyticus infection. FISH & SHELLFISH IMMUNOLOGY 2023; 133:108533. [PMID: 36639067 DOI: 10.1016/j.fsi.2023.108533] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 01/03/2023] [Accepted: 01/09/2023] [Indexed: 06/17/2023]
Abstract
Macrobrachium rosenbergii as one of the common freshwater prawn species in Southeast Asia, which breeding industry is seriously threatened by vibriosis and causes high mortality. In this study, the RNA-seq was employed for assessing the M. rosenbergii hemocytes transcriptomes following Vibrio parahaemolyticus challenge. After challenge for 6 h (h), there were overall 1849 DEGs or differentially expressed genes, including 1542 up-regulated and 307 down-regulated genes, and there was a total of 1048 DEGs, including 510 up-regulated genes and 538 down-regulated genes, after challenge for 12 h. Mitogen-activated protein kinase (MAPK) immune-related pathways, Toll, immune deficiency (IMD), and Janus kinase (JAK)/signal transducer and activator of transcription (STAT) were among the immune pathways where a lot of the DEGs were connected. The expression patterns of 18 chosen immune-related genes were examined utilizing qRT-PCR or quantitative real-time polymerase chain reaction, which revealed that the V. parahaemolyticus infection activated the M. rosenbergii's immune response. Permutational multivariate analysis of variance (PERMANOVA) showed that V. parahaemolyticus infection modulated immune regulation and apoptosis pathways. The gathered information provided new insight into M. rosenbergii's immunity and suggested a novel approach to fight against bacterial infection.

Vibrio parahaemolyticus and Vibrio vulnificus in vitro colonization on plastics influenced by temperature and strain variability. Front Microbiol 2023; 13:1099502. [PMID: 36704570 PMCID: PMC9871911 DOI: 10.3389/fmicb.2022.1099502] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 12/16/2022] [Indexed: 01/12/2023] Open
Abstract
Marine bacteria often exist in biofilms as communities attached to surfaces, like plastic. Growing concerns exist regarding marine plastics acting as potential vectors of pathogenic Vibrio, especially in a changing climate. It has been generalized that Vibrio vulnificus and Vibrio parahaemolyticus often attach to plastic surfaces. Different strains of these Vibrios exist having different growth and biofilm-forming properties. This study evaluated how temperature and strain variability affect V. parahaemolyticus and V. vulnificus biofilm formation and characteristics on glass (GL), low-density polyethylene (LDPE), polypropylene (PP), and polystyrene (PS). All strains of both species attached to GL and all plastics at 25, 30, and 35°C. As a species, V. vulnificus produced more biofilm on PS (p ≤ 0.05) compared to GL, and biofilm biomass was enhanced at 25°C compared to 30° (p ≤ 0.01) and 35°C (p ≤ 0.01). However, all individual strains' biofilm biomass and cell densities varied greatly at all temperatures tested. Comparisons of biofilm-forming strains for each species revealed a positive correlation (r = 0.58) between their dry biomass weight and OD570 values from crystal violet staining, and total dry biofilm biomass for both species was greater (p ≤ 0.01) on plastics compared to GL. It was also found that extracellular polymeric substance (EPS) chemical characteristics were similar on all plastics of both species, with extracellular proteins mainly contributing to the composition of EPS. All strains were hydrophobic at 25, 30, and 35°C, further illustrating both species' affinity for potential attachment to plastics. Taken together, this study suggests that different strains of V. parahaemolyticus and V. vulnificus can rapidly form biofilms with high cell densities on different plastic types in vitro. However, the biofilm process is highly variable and is species-, strain-specific, and dependent on plastic type, especially under different temperatures.

Abstract
The giant freshwater prawn, Macrobrachium rosenbergii, is an important and economical aquaculture species widely farmed in tropical and subtropical areas of the world. A new disease, "water bubble disease (WBD)", has emerged and resulted in a large loss of M. rosenbergii cultured in China. A water bubble with a diameter of about 7 mm under the carapace represents the main clinical sign of diseased prawns. In the present study, Citrobacter freundii was isolated and identified from the water bubble. The optimum temperature, pH, and salinity of the C. freundii were 32 °C, 6, and 1%, respectively. A challenging experiment showed that C. freundii caused the same typical signs of WBD in prawns. Median lethal dose of the C. freundii to prawn was 104.94 CFU/g. According to the antibiogram tests of C. freundii, florfenicol and ofloxacin were selected to evaluate their therapeutic effects against C. freundii in prawn. After the challenge with C. freundii, 86.67% and 72.22% survival of protective effects against C. freundii were evaluated in the oral florfenicol pellets and oral ofloxacin pellets feding prawns, respectively, whereas the mortality of prawns without fed antibiotics was 93%. After antibiotic treatment and C. freundii infection, the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione S-transferase (GST), malondialdehyde (MDA), acid phosphatase (ACP), alkaline phosphatase (ALP), and lysozyme (LZM) in the hemolymph and hepatopancreas of the prawns and the immune-related gene expression levels of Cu/Zn-SOD, CAT, GPx, GST, LZM, ACP, anti-lipopolysaccharide factor, crustin, cyclophilin A, and C-type lectin in hepatopancreas were all significantly changed, indicating that innate immune responses were induced by C. freundii. These results can be beneficial for the prevention and control of C. freundii in prawns.

Abstract
Shrimp aquaculture industry has steadily increased with demand and development of aquaculture technology. In recent years, frequent diseases have become a major risk factor for shrimp aquaculture, such as a drastically reduced the production of shrimp and causing national economic loss. Among them, shrimp bacterial diseases such as hepatopancreatic necrosis disease (AHPND) and necrotizing hepatopancreatitis (NHP-B) and parasitic disease such as Aphanomyces astaci (crayfish plague) are emerging and evolving into new types. OIE (World Organization for Animal Health) regularly updates information on diseases in the Aquatic Code and Aquatic Manual, but in-depth information on the shrimp diseases are lacking. Therefore, the purpose of this review is to provide information necessary for the response and prevention of shrimp diseases by understanding the characteristics and diagnosis of shrimp diseases designated by OIE.

In Silico Approach Gives Insights into Ig-like Fold Containing Proteins in Vibrio parahaemolyticus: A Focus on the Fibrillar Adhesins. Toxins (Basel) 2022; 14:toxins14020133.

Abstract
Immunoglobulin-like (Ig-like) fold domains are abundant on the surface of bacteria, where they are required for cell-to-cell recognition, adhesion, biofilm formation, and conjugative transfer. Fibrillar adhesins are proteins with Ig-like fold(s) that have filamentous structures at the cell surface, being thinner and more flexible than pili. While the roles of fibrillar adhesins have been proposed in bacteria overall, their characterization in Vibrio parahaemolyticus has not been established and, therefore, understanding about fibrillar adhesins remain limited in V. parahaemolyticus. This in silico analysis can aid in the systematic identification of Ig-like-folded and fibrillar adhesin-like proteins in V. parahaemolyticus, opening new avenues for disease prevention by interfering in microbial interaction between V. parahaemolyticus and the host.

Abstract
Kruppel-like factors (KLFs) belong to a family of zinc finger-containing transcription factors that are widely present in eukaryotes. In the present study, a novel KLF from the giant river prawn Macrobrachium rosenbergii (designated as MrKLF) was successfully cloned and characterized. The full-length cDNA of MrKLF was 1799 bp with an open reading frame of 1332 bp that encodes a putative protein of 444 amino acids, including three conserved ZnF_C2H2 domains at the C-terminus. Multiple alignment analysis showed that MrKLF and other crustacean KLFs shared high similarity. Quantitative real-time PCR analysis revealed that MrKLF mRNA was found in different tissues of prawns and detected in the gills, hepatopancreas, and intestines. After the challenge with Vibrio parahaemolyticus and Aeromonas hydrophila, different expression patterns of MrKLF in the gills, intestines, and hepatopancreas were observed. RNA interference analysis indicated that MrKLF was involved in regulating the expression of four antimicrobial peptides, namely, Crustin (Crus) 2, Crus8, anti-lipopolysaccharide factor (ALF) 1, and ALF3. These results help promote research on M. rosenbergii innate immunity.

Abstract
The caspase is an essential module in the Drosophila immune deficiency (IMD) pathway, which plays a crucial role in countering pathogen infection. In this study, a gene named PcCaspase-3C was found in Procambarus clarkia with a full-length of 4684 bp, including a 1572 bp opening reading frame, which encoded a putative protein of 523 amino acids. PcCaspase-3C contained a CASc domain constituted of 237 amino acids. The PcCaspase-3C gene was primarily expressed in heart, stomach, and intestine, while less in gonad, hepatopancreas, gills, and hemocytes, with the least expression in muscle. Infection with Staphyloccocus aureus, Vibrio parahaemolyticus or white spot syndrome virus (WSSV) induced an up-regulated expression of PcCaspase-3C in intestine or stomach to varying degrees. When PcCaspase-3C was silenced by double-stranded RNA, the expression of some antimicrobial peptides such as ALF2, ALF5, ALF6, Cru3, Cru4, and Lys was significantly inhibited. In addition, silencing of PcCaspase-3C accelerated infection with WSSV in vivo. According to these results, we suggest that PcCaspase-3C might play a crucial role in the immune response of P. clarkia against pathogenic bacterial and viral infections.

Gut Pathog 2019; 11:39.

Abstract
Background Penaeus monodon is the second most widely cultured marine shrimp species in the global shrimp aquaculture industry. However, the growth of P. monodon production has been constantly impaired by disease outbreaks. Recently, there is a lethal bacterial infection, known as acute hepatopancreatic necrosis disease (AHPND) caused by Vibrio parahaemolyticus AHPND strain (VpAHPND), which led to mass mortalities in P. monodon. Unfortunately, there is still insufficient knowledge about the underlying immune response of P. monodon upon AHPND infection. The present study aims to provide an insight into the antibacterial immune response elicited by P. monodon hepatopancreas towards AHPND infection. Methods We have employed high-throughput RNA-Seq technology to uncover the transcriptome changes of P. monodon hepatopancreas when challenged with VpAHPND. The shrimps were challenged with VpAHPND through immersion method with dissected hepatopancreas samples for the control group (APm-CTL) and treatment group at 3 (APm-T3), 6 (APm-T6), and 24 (APm-T24) hours post-AHPND infection sent for RNA-Seq. The transcriptome de novo assembly and Unigene expression determination were conducted using Trinity, Tgicl, Bowtie2, and RSEM software. The differentially expressed transcripts were functionally annotated mainly through COG, GO, and KEGG databases. Results The sequencing reads generated were filtered to obtain 312.77 Mb clean reads and assembled into 48662 Unigenes. Based on the DEGs pattern identified, it is inferred that the PAMPs carried by VpAHPND or associated toxins are capable of activating PRRs, which leads to subsequent pathway activation, transcriptional modification, and antibacterial responses (Phagocytosis, AMPs, proPO system). DAMPs are released in response to cell stress or damage to further activate the sequential immune responses. The comprehensive interactions between VpAHPND, chitin, GbpA, mucin, chitinase, and chitin deacetylase were postulated to be involved in bacterial colonization or antibacterial response. Conclusions The outcomes of this research correlate the different stages of P. monodon immune response to different time points of AHPND infection. This finding supports the development of biomarkers for the detection of early stages of VpAHPND colonization in P. monodon through host immune expression changes. The potential genes to be utilized as biomarkers include but not limited to C-type lectin, HMGB1, IMD, ALF, serine proteinase, and DSCAM.

Abstract
The tetraspanins, representing a conserved superfamily of four-span membrane proteins, are highly involved in viral and bacterial infections. Thus far, the function of the tetraspanins in crustaceans remains largely unknown. In this study, we report the cloning and expression analysis of a tetraspanin 8 from the giant freshwater prawn, Macrobrachium rosenbergii (named as MrTspan8). MrTspan8 contains a 720-bp open reading frame encoding a 239-amino acids protein, which exhibits four transmembrane domains and two extracellular loops that are typical for tetraspanins. MrTspan8 was found to be widely expressed in a variety of prawn tissues including heart, gill, muscle, gut, and hepatopancreas. Additionally, MrTspan8 expression was significantly increased in the hepatopancreas and gill of the prawns challenged by the bacterial pathogen Aeromonas hydrophila. Moreover, we show that pre-incubation of the peptides from the large extracellular loop of MrTSPAN8 protein reduced the cell death caused by A. hydrophila infection in prawn tissue, suggesting that MrTSPAN8 could be a mediator for bacterial infection to prawn.

FISH & SHELLFISH IMMUNOLOGY 2018; 82:350-360. [PMID: 30138666 DOI: 10.1016/j.fsi.2018.08.036] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Revised: 08/07/2018] [Accepted: 08/14/2018] [Indexed: 06/08/2023]
Abstract
Fibrinogen-related proteins (FREPs) are widely found in vertebrates and invertebrates, and they play crucial roles in innate immunity. Here, a new FREP named as MrFREP was identified from giant freshwater prawn (Macrobrachium rosenbergii). The full-length cDNA of MrFREP measures 1649 bp in length and consists of a 1086 bp open reading frame encoding a polypeptide composed of 361 amino acids. The MrFREP sequence has a signal peptide with 20 amino acids and a fibrinogen-related domain (FReD) with 223 amino acids. Phylogenetic analysis showed that MrFREP was grouped with FREPs from Marsupenaeus japonicus and Litopenaeus vannamei. BLASTp results showed that it had 43% identity with a FREP from M. japonicus. The expression of MrFREP was higher in gills, intestine, and hepatopancreas than in hemocytes, heart, stomach, and muscles. The expression levels of MrFREP in gills and intestine were obviously upregulated after they were exposed to Vibrio parahaemolyticus or White spot syndrome virus infection. Recombinant MrFReD protein (rMrFReD) could bind to Gram-positive and Gram-negative bacteria and agglutinate the tested bacteria in the presence of calcium. rMrFReD demonstrated lipopolysaccharide and peptidoglycan binding activities. rMrFReD could accelerate the clearance of V. parahaemolyticus in vivo. These results suggested that MrFREP could function as a pattern recognition receptor contributing to the innate immunity of M. rosenbergii.

Abstract
Wnt signaling plays important roles in a variety of developmental and pathological processes. Here we show that Wntless, the main regulator for Wnt secretion, is involved in the innate immune response of the giant freshwater prawn, Macrobrachium rosenbergii. The full-length cDNA of the prawn Wntless (named MrWntless) is 2173 bp in length and contains a 1602-bp open reading frame (ORF), which is conceptually translated into a 533-amino acids sequence. MrWntless protein contains a highly conserved Wnt-binding domain which is required for secretion of Wnt ligands, and exhibits 57-67% identity with known Wntless proteins of other animals. MrWntless was found to be expressed in a variety of prawn tissues including heart, gill, muscle, gut, hepatopancreas and ovary. Moreover, MrWntless expression was significantly increased in the hepatopancreas and gill of the prawns challenged by the bacterial pathogen Aeromonas hydrophila and Vibrio parahaemolyticus. Knockdown of MrWntless by RNA interference in prawns led to dramatically decreased MrWntless expression of approximately 70%. Furthermore, the cumulative mortality rate of the prawn injected with MrWntless dsRNA was greatly increased in response to A. hydrophila challenge compared with the control prawns. Taken together, we provide evidence that prawn Wntless is important for their innate immune response against bacterial pathogens.

Abstract
Methyl farnesoate (MF), the crustacean juvenile hormone (JH), plays critical roles in various physiological processes in crustaceans. The titer of MF is precisely regulated by specific carboxylesterase. Here, we report for the first time that the cloning and expression analysis of a JH esterase-like carboxylesterase from the prawn Macrobrachium rosenbergii (named as MrCXE). MrCXE contained a 1935-bp open reading frame (ORF) conceptually translated into a 644-amino acids protein. MrCXE protein shared the highest identity (36%) with JH esterase-like carboxylesterase from the swimming crab, Portunus trituberculatus and exhibited the typical motifs of JH esterase-like carboxylesterases. MrCXE was most abundantly expressed in hepatopancreas, the major tissue for MF metabolism. MrCXE was expressed at a low level in gut and was not detected in other tissues. Additionally, MrCXE expression was upregulated in hepatopancreas by eyestalk ablation to increase MF level. Furthermore, the mRNA level of MrCXE was significantly increased in the hepatopancreas when challenged by the bacterial pathogens Aeromonas hydrophila and Vibrio parahaemolyticus. To our knowledge, this is the first report that the JH esterase-like carboxylesterase is involved in the innate immune response of the crustaceans.

FISH & SHELLFISH IMMUNOLOGY 2017; 68:488-499.

Abstract
Ficolins have crucial functions in recognizing and eliminating pathogens in innate immunity. In this study, we identified two ficolin-like genes from the oriental river prawn, Macrobrachium nipponense. These genes were designated as MnFico1 and MnFico2. MnFico1 cDNA has 1600 bp, whereas MnFico2 has 1486 bp. In addition to a coiled-coil region or a low complexity region, the two ficolins both contained a signal peptide and a fibrinogen-related domain. qRT-PCR results showed that the highest expression level of MnFico1 expression was in the gills, whereas that of MnFico2 was in the heart. The transcripts of MnFico1 and MnFico2 could both respond to bacteria challenge. The transcription of antilipopolysaccharide factors ALFs (MnALF1 and MnALF2) and crustin genes (MnCru4, MnCru5, MnCru6, and MnCru7) was inhibited in the gills of MnFico1 or MnFico2 knockdown prawns at 24 h Vibrio parahaemolyticus challenge. Recombinant proteins of rMnFico1 and rMnFico2 could bind toward diverse bacteria and agglutinate Gram-negative and Gram-positive bacteria with the presence of calcium (Ca2+). rMnFico1 and rMnFico2 proteins also have lipopolysaccharide and peptidoglycan binding activity. Both recombinant ficolin proteins could help the prawn to facilitate the clearance of V. parahaemolyticus in vivo. Our results suggested that MnFico1 and MnFico2 might serve as pattern recognition receptors in M. nipponense.

Tiruvayipati S, Bhassu S. Host, pathogen and environment: a bacterial gbpA gene expression study in response to magnesium environment and presence of prawn carapace and commercial chitin. Gut Pathog 2016; 8:23. [PMID: 27231485 PMCID: PMC4880808 DOI: 10.1186/s13099-016-0105-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2015] [Accepted: 05/11/2016] [Indexed: 11/30/2022] Open
Abstract
Background Vibrio parahaemolyticus is a Gram-negative halophilic bacterium which is found largely in estuarine and coastal waters. The bacteria has been a main focus in gastro-intestinal infections caused primarily due to the consumption of contaminated seafood. It was shown to survive in magnesium concentrations as high as 300 mM which are toxic to various other micro-organisms. Several genes of V. parahaemolyticus were studied, among which gbpA (N-acetyl glucosamine binding protein) was reported in Vibrio cholerae. Methods The current study investigates the V. parahaemolyticus gbpA gene expression at different concentrations of magnesium sulfate heptahydrate (MgSO4·7H2O, chosen as the magnesium environment), in the presence of the host’s (prawn) carapace and the mimicked carapace [commercial chitin flakes (Sigma)]. The concentrations of MgSO4·7H2O utilized were approximately 0, 1, 75, 137, 225 and 300 mM. These were selected based upon the survival conditions required by prawn and bacteria, respectively. 0.05 gm/3 ml of carapace (by dry weight) and commercial chitin flakes were used in the experiments. Bacterial count was performed for the biological triplicates for the 3 experimental setups. The genome of Vibrio parahaemolyticus PCV08-7 (VPPCV08-7) was used as a reference, based on whose translated gbpA gene the probable protein-chemical interactions were determined on the STITCH database. Results The GbpA protein was shown to interact with chitin on the STITCH database. In our experiments, the gbpA showed lower gene expression levels at different MgSO4·7H2O concentrations in the presence of chitin and carapace, than with the presence of only MgSO4•7H2O. In addition, the bacterial count for various concentrations of magnesium used, revealed a distinct decrease in bacterial count within and among each of the three experimental setups. Conclusion In the presence of only magnesium, an increase in the gbpA expression with neither chitin nor carapace and vice versa supported by the results from the bacterial counts could help further studies to prove that the moulting phase of prawns may trigger increased expression of the V. parahaemolyticus gbpA gene.
