[PMID: 38266793 DOI: 10.1016/j.fsi.2024.109403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 01/20/2024] [Accepted: 01/21/2024] [Indexed: 01/26/2024]
Abstract
The high morbidity and mortality of Macrobrachium nipponense occurred in several farms in China, with cardinal symptoms of slow swimming, loss of appetite, empty of intestine, reddening of the hepatopancreas and gills. The pathogen has been confirmed as Decapod Iridescent Virus 1 (DIV1), namely DIV1-mn, by molecular epidemiology, histopathological examination, TEM observation, challenge experiment, and viral load detection. Histopathological analysis showed severe damage in hepatopancreas and gills of diseased prawns, exhibited few eosinophilic inclusions and pyknosis, and TEM of diseased prawns revealed that icosahedral virus particles existed in hepatopancreas and gill, which confirmed the disease of the farmed prawns caused by the DIV1 infection. Besides, challenge tests showed LD50 of DIV1 to M. nipponense was determined to be 2.14 × 104 copies/mL, and real-time PCR revealed that M. nipponense had a very high DIV1 load in the hemocytes, gills and hepatopancreas after infection. Furthermore, qRT-PCR was undertaken to investigated the expression of six immune-related genes in DIV1-infected M. nipponense after different time points, and the results revealed UCHL3, Relish, Gly-Cru2, CTL, MyD88 and Hemocyanin were significantly up-regulated in hemocytes, gills and hepatopancreas, which revealed various expression patterns in response to DIV1 infection. This study revealed that DIV1 infection is responsible for the mass mortality of M. nipponense, one of the important crustacean species, indicating its high susceptibility to DIV1. Moreover, this study will contribute to exploring the interaction between the host and DIV1 infection, specifically in terms of understanding how M. nipponense recognizes and eliminates the invading of DIV1.

Utilisation of probiotics for disease management in giant freshwater prawn (Macrobrachium rosenbergii): Administration methods, antagonistic effects and immune response. JOURNAL OF FISH DISEASES 2023; 46:1321-1336. [PMID: 37658593 DOI: 10.1111/jfd.13850] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 08/03/2023] [Accepted: 08/07/2023] [Indexed: 09/03/2023]
Abstract
The giant freshwater prawn (Macrobrachium rosenbergii) is a high-yielding prawn variety well-received worldwide due to its ability to adapt to freshwater culture systems. Macrobrachium rosenbergii is an alternative to shrimp typically obtained from marine and brackish aquaculture systems. However, the use of intensive culture systems can lead to disease outbreaks, particularly in larval and post-larval stages, caused by pathogenic agents such as viruses, bacteria, fungi, yeasts and protozoans. White tail disease (viral), white spot syndrome (viral) and bacterial necrosis are examples of economically significant diseases. Given the increasing antibiotic resistance of disease-causing microorganisms, probiotics have emerged as promising alternatives for disease control. Probiotics are live active microbes that are introduced into a target host in an adequate number or dose to promote its health. In the present paper, we first discuss the diseases that occur in M. rosenbergii production, followed by an in-depth discussion on probiotics. We elaborate on the common methods of probiotics administration and explain the beneficial health effects of probiotics as immunity enhancers. Moreover, we discuss the antagonistic effects of probiotics on pathogenic microorganisms. Altogether, this paper provides a comprehensive overview of disease control in M. rosenbergii aquaculture through the use of probiotics, which could enhance the sustainability of prawn culture.

Abstract
A variety of reoviruses have been described in crustacean hosts, including shrimp, crayfish, prawn, and especially in crabs. However, only one genus of crustacean reovirus - Cardoreovirus - has been formally recognized by ICTV (International Committee on Taxonomy of Viruses) and most crustacean reoviruses remain unclassified. This arises in part from ambiguous or incomplete information on which to categorize them. In recent years, increased availability of crustacean reovirus genomic sequences is making the discovery and classification of crustacean reoviruses faster and more certain. This minireview describes the properties of the reoviruses infecting crustaceans and suggests an overall classification of brachyuran crustacean reoviruses based on a combination of morphology, host, genome organization pattern and phylogenetic sequence analysis.

FISH & SHELLFISH IMMUNOLOGY 2020; 101:225-233.

Abstract
The Wnt signal transduction pathway is involved in a wide variety of cellular processes, including cell proliferation, differentiation, apoptosis, and immunity against microbial infection. In the current study, we cloned and characterized two Wnt homologues (Mn-Wnt4 and Mn-Wnt16) in Macrobrachium nipponense. The full length cDNA of Mn-Wnt4 was 3144 bp with a 1074 bp open reading frame (ORF) that encoded a protein containing 358 amino acid residues. The full length cDNA of Mn-Wnt16 transcript was 2893 bp with a 1281 bp ORF that encoded a 427 amino acid protein. Mn-Wnt4 and Mn-Wnt16 proteins contained a highly conserved WNT1 domain. Tissue distribution analysis showed that Mn-Wnt4 and Mn-Wnt16 were highly expressed in the stomach. The transcriptional levels of Mn-Wnt4 and Mn-Wnt16 in the stomach were upregulated at most tested time points after bacterial (Staphylococcus aureus and Vibrio parahaemolyticus) and viral (White spot syndrome virus) infection. Moreover, the expression levels of some antimicrobial peptides (AMPs) (including anti-lipopolysaccharide factor [ALF] and crustin [CRU]) were upregulated after V. parahaemolyticus infection. We further used dsRNA-mediated RNA interference technology to explore the relationship between these two Wnt genes and the expression levels of AMPs during V. parahaemolyticus infection. Mn-Wnt4 knockdown could significantly inhibit the expression of ALF1 and CRU4 in the stomach of V. parahaemolyticus-injected prawns, whereas Mn-Wnt16 silencing could result in the inhibition of the expression level of CRU3 and CRU4 in the stomach of V. parahaemolyticus-infected prawns. These findings indicated that the Wnt gene family might participate in the body's innate immune response to Vibrio infection by regulating the synthesis of a variety of AMPs. Our study will help to understand the role of the Wnt signaling pathway in the immune response of crustaceans.

Vogt G. Cytopathology and immune response in the hepatopancreas of decapod crustaceans. DISEASES OF AQUATIC ORGANISMS 2020; 138:41-88. [PMID: 32103822 DOI: 10.3354/dao03443] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/10/2023]
Abstract
The hepatopancreas of decapod crustaceans is used as an example to illustrate the range of cytopathologies, detoxification mechanisms, and immune responses that environmental toxicants and pathogens can induce in a single organ. The hepatopancreas is the central metabolic organ of decapods and consists of hundreds of blindly-ending tubules and intertubular spaces. The tubular epithelium contains 5 structurally and functionally different cell types, and the interstitium contains haemolymph, haemocytes, connective tissue, and fixed phagocytes. Some physiological conditions such as moulting and starvation cause marked but reversible ultrastructural alterations of the epithelial cells. Environmental toxicants induce either detoxification mechanisms or structural damage in cells, depending on toxicant and concentration. The hepatopancreas is also a main target organ for pathogens, mainly viruses, bacteria, and protists that enter the body via the digestive tract and gills and replicate in the hepatopancreatocytes. The cytopathologies caused by toxicants and pathogens affect single cell types specifically or, more often, several cell types simultaneously. Pathogenesis often begins in a certain cell organelle such as the nucleus, mitochondrion, or endoplasmic reticulum, spreads to other organelles, and ends with death of the infected cell. Fixed phagocytes in the interstitium capture and degrade pathogens that move from the infected tubules into the intertubular spaces or enter the hepatopancreas via circulation. Relatively few disease agents elicit the melanisation and encapsulation reaction that encloses infected tubules by a rigid melanised capsule and kills the entrapped pathogens.
