Zhang L, Liu K, Liu M, Hu J, Bao Z, Wang M. Development of a real-time enzymatic recombinase amplification assay for rapid detection of infectious hypodermal and hematopoietic necrosis virus (IHHNV) in shrimp Penaeus vannamei. J Invertebr Pathol 2023; 201:108024. [PMID: 37992986 DOI: 10.1016/j.jip.2023.108024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 11/18/2023] [Accepted: 11/18/2023] [Indexed: 11/24/2023]
Abstract
Infectious hypodermal and hematopoietic necrosis virus (IHHNV) is classified as a reportable crustacean disease by the World Organisation for Animal Health (WOAH), which causes poor growth in Penaeus vannamei. According to genome sequence alignment analysis, enzymatic recombinase amplification (ERA) primers and probe were designed based on the ORF1 region of IHHNV, and a real-time ERA assay for IHHNV detection (IHHNV-ERA) was established. The experimental results show that IHHNV-F2/IHHNV-R2 and IHHNV-Probe can effectively amplify the target gene, and the sensitivity is 1.4 × 101 copies/μL within 14.97 ± 0.19 min, while the qPCR using primers 309F/309R could reach the detection limit of 1.4 × 101 copies/μL within 21.76 ± 0.63 min, and the sensitivity results of one-step PCR could be as low as 1.4 copies/μL with expense of time and false positives. The IHHNV-ERA system can effectively amplify the target gene at 42 ℃ within 20 min, and has no cross-reaction with white spot syndrome virus (WSSV), Ecytonucleospora hepatopenaei (EHP), Vibrio parahaemolyticus causing acute hepatopancreatic necrosis disease (VpAHPND), and healthy shrimp genomic DNA. Test results of practical samples showed that the detection rate of IHHNV-ERA (18/20) was better than the industrial standard qPCR assay (17/20). Compared with the existing technology, the useful results of this detection assay are: (1) get rid of the dependence on the thermal cycle instrument in the PCR process; (2) the experimental procedure is simple, time-consuming and fast; (3) the detection sensitivity is high. This study provides an ERA based detection assay for IHHNV, which can be used not only for the rapid detection of IHHNV infection, but also for the field screening of pathogens. This assay can also be applied to clinical inspection, customs detection, enterprise quality inspection and other fields, and has obvious practical application value.

Pathogens 2023; 12:1038. [PMID: 37623998 PMCID: PMC10459460 DOI: 10.3390/pathogens12081038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 07/31/2023] [Accepted: 08/11/2023] [Indexed: 08/26/2023] Open
Abstract
Procambarus clarkii is an important economic aquaculture species worldwide. Infectious hypodermal and hematopoietic necrosis virus (IHHNV) infects numerous crustacean hosts, including P. clarkii. However, there have been few reports on the prevalence of IHHNV in P. clarkii. In this study, 200 farmed P. clarkii were collected from Anhui, Jiangsu, Zhejiang, Hunan, Hubei, and Sichuan provinces in China. PCR detection was employed per the protocol by the World Organization for Animal Health (WOAH) to identify and detect the presence of IHHNV. The positive rate of IHHNV in different provinces ranged from 16.7 to 56.7%, and the overall IHHNV-positive rate was 38.5%. IHHNV strains isolated in this study related closely to infectious IHHNV and split into two major distinct branches. Besides, the IHHNV strains shared a high homology (93.4-99.4%). These findings suggest that a high prevalence of IHHNV was established in farmed P. clarkii in the middle and lower reaches of the Yangtze River.

Abstract
Shrimp is one of the most valuable aquaculture species globally, and the most internationally traded seafood product. Consequently, shrimp aquaculture practices have received increasing attention due to their high value and levels of demand, and this has contributed to economic growth in many developing countries. The global production of shrimp reached approximately 6.5 million t in 2019 and the shrimp aquaculture industry has consequently become a large-scale operation. However, the expansion of shrimp aquaculture has also been accompanied by various disease outbreaks, leading to large losses in shrimp production. Among the diseases, there are various viral diseases which can cause serious damage when compared to bacterial and fungi-based illness. In addition, new viral diseases occur rapidly, and existing diseases can evolve into new types. To address this, the review presented here will provide information on the DNA and RNA of shrimp viral diseases that have been designated by the World Organization for Animal Health and identify the latest shrimp disease trends.

Abstract
Viral capsid proteins play an important role in the viral infection process. To identify the cellular proteins in shrimp that interact with the Penaeus stylirostris densovirus capsid protein (PstDNV-CP), we constructed a yeast two-hybrid (Y2H) cDNA library of the muscle tissue of Litopenaeus vannamei, and hybridized the bait vector pGBKT7-CP with this library. Cloning and sequencing showed that the shrimp protein interacting with PstDNV-CP was a homolog of BRCA2 and CDKN1A(p21)-interacting protein (BCCIP). We named this protein L. vannamei BCCIP (LvBCCIP). Further analysis showed that LvBCCIP interacted with L. vannamei calmodulin (LvCaM). We validated the interactions between PstDNV-CP and LvBCCIP, and between LvBCCIP and LvCaM, with GST pulldown assays. The gene expression of LvBCCIP increased significantly after PstDNV challenge. In addition, the PstDNV titer of PstDNV-challenged shrimp was significantly reduced after LvBCCIP expression was inhibited using double-stranded RNA (dsRNA) interference. These results indicated that LvBCCIP is critical to PstDNV pathogenesis in L. vannamei. Interestingly, the growth rate of L. vannamei was significantly reduced when LvBCCIP gene expression was silenced, indicating that LvBCCIP may also be associated with growth regulation in L. vannamei. Thus, the interaction between PstDNV-CP and LvBCCIP might explain why PstDNV infection leads to runt-deformity syndrome in shrimp.

Abstract
The Penaeus stylirostris densovirus (PstDNV) (also known as infectious hypodermal and hematopoietic necrosis virus, IHHNV), a very small DNA virus, is a major shrimp pathogen. The PstDNV genome encodes only two nonstructural proteins and one capsid protein. This virus is thus an ideal, simple model for the investigation of virus-host interactions. To explore the role of the PstDNV capsid in viral infections, a yeast two-hybrid (Y2H) cDNA library was constructed based on Pacific white shrimp, Litopenaeus vannamei mRNA. The Y2H library was then screened, using the PstDNV capsid protein as bait. We identified a host protein that interacted strongly with the PstDNV capsid as L. vannamei troponin I (LvTnI). An in vitro co-immunoprecipitation experiment further supported this interaction. In addition, an in vivo neutralization experiment showed that the vaccination with anti-LvTnI significantly reduced PstDNV copies in PstDNV-challenged shrimp, indicating that the interaction between the PstDNV capsid and cellular LvTnI is essential for PstDNV infection. This result has important implications for our understanding of the mechanisms by which PstDNV infects shrimp.

Prevalence and genomic analysis of infectious hypodermal and hematopoietic necrosis virus (IHHNV) in Litopenaeus vannamei shrimp farmed in Shanghai, China. Arch Virol 2016; 161:3189-201.

Abstract
Infectious hypodermal and hematopoietic necrosis virus (IHHNV) is prevalent among farmed shrimp and results in significant reductions in shrimp production. In order to gain a better understanding of the prevalence of IHHNV in the Litopenaeus vannamei shrimp population of Shanghai, China, samples were collected during two cultivation seasons and subjected to diagnostic PCR. The results of this study showed that 167 out of 200 shrimp were positive for IHHNV, indicating a high viral prevalence (83.5 %) in farmed shrimp populations. Our results also indicated that there was a moderate correlation between IHHNV prevalence and water temperature, salinity and pH and only a slight correlation with the concentration of dissolved oxygen (DO). A mathematical model was developed in order to predict the relationship between these four characteristics of water quality and IHHNV prevalence, ultimately resulting in an estimate of the best water quality criteria (IHHNV prevalence = 0) where T = 30 °C pH = 8.0, DO = 18.3 mg/L, and salinity = 1.5 ‰. Additionally, two IHHNV genotypes were identified, the sequencing of which revealed a high similarity to the known IHHNV genotypes based on a comparison of their nucleotide and amino acid sequences. Two types of repetitive sequences were detected at both the 5' and 3' ends of the non-coding regions, which are commonly found in other IHHNV genomic sequences. Phylogenetic analysis indicated that the IHHNV Shanghai genotypes were closely related to strains from Ganyu and Sheyang, but not to strains originating from Fujian, China. This finding suggests that IHHNVs have emerged independently several times in China.

Abstract
Decapod Penstyldensovirus 1, previously named as infectious hypodermal and hematopoietic necrosis virus (IHHNV), is an economically important pathogen that causes shrimp diseases worldwide. However, a rapid method for cloning full-length IHHNV genome sequences is still lacking, which makes it difficult to study the genomics and molecular epidemiology of IHHNV. Here, a novel and rapid PCR technique was developed to determine the complete genomic sequences of IHHNV. The IHHNV genome was amplified in two overlapping fragments which each yielded a 2kb PCR product covering the first half or the second half of IHHNV genome, respectively. Using this method, six complete genomic sequences of IHHNV, which were collected from different regions of Zhejiang province in China, were cloned and sequenced successfully. The new cloning method will greatly facilitate the study on the genomics and molecular epidemiology of IHHNV.

Abstract
As shrimp aquaculture has evolved from a subsistent farming activity to an economically important global industry, viral diseases have also become a serious threat to the sustainable growth and productivity of this industry. Parvoviruses represent an economically important group of viruses that has greatly affected shrimp aquaculture. In the early 1980s, an outbreak of a shrimp parvovirus, infectious hypodermal and hematopoietic necrosis virus (IHHNV), led to the collapse of penaeid shrimp farming in the Americas. Since then, considerable progress has been made in characterizing the parvoviruses of shrimp and developing diagnostic methods aimed to preventing the spread of diseases caused by these viruses. To date, four parvoviruses are known that infect shrimp; these include IHHNV, hepatopancreatic parvovirus (HPV), spawner-isolated mortality virus (SMV), and lymphoid organ parvo-like virus. Due to the economic repercussions that IHHNV and HPV outbreaks have caused to shrimp farming over the years, studies have been focused mostly on these two pathogens, while information on SMV and LPV remains limited. IHHNV was the first shrimp virus to be sequenced and the first for which highly sensitive diagnostic methods were developed. IHHNV-resistant lines of shrimp were also developed to mitigate the losses caused by this virus. While the losses due to IHHNV have been largely contained in recent years, reports of HPV-induced mortalities in larval stages in hatchery and losses due to reduced growth have increased. This review presents a comprehensive account of the history and current knowledge on the biology, diagnostics methods, genomic features, mechanisms of evolution, and management strategies of shrimp parvoviruses. We also highlighted areas where research efforts should be focused in order to gain further insight on the mechanisms of parvoviral pathogenicity in shrimp that will help to prevent future losses caused by these viruses.

Abstract
Infectious hypodermal and hematopoietic necrosis virus (IHHNV) is one of the major viral pathogens of penaeid shrimps worldwide, which has resulted in severe mortalities of up to 90 % in cultured Penaeus (Litopenaeus) stylirostris from Hawaii and hence designated Penaeus stylirostris densovirus (PstDNV). IHHNV is distributed in shrimp culture facilities worldwide. It causes large economic loss to the shrimp farming industry. Our knowledge about the natural reservoirs of IHHNV is still scarce. Recent studies suggest that there is sufficient sequence variation among the isolates from different locations in Asia, suggesting multiple geographical strains of the virus. Four complete genomes and several partial sequences of the virus are available in the GenBank. Complete genome information would be useful for assessing the specificity of diagnostics for viruses from different geographical areas. Comparisons of complete genome sequences will help us gain insights into point mutations that can affect virulence of the virus. In addition, because of unavailability of shrimp cell lines for culturing IHHNV in vitro, quantification of virus is difficult. The recent progress in research regarding clinical signs, geographical distribution, complete genome sequence and genetic variation, transmission has made it possible to obtain information on IHHNV. A comprehensive understanding of IHHNV infection process, pathogenesis, structural proteins and replication is essential for developing prevention measures. To date, no effective prophylactic measure for IHHNV infection is available for shrimp to reduce its impact. This review provides an overview of key issues regarding IHHNV infection and disease in commercially important shrimp species.
