No single PCR test is sufficient to determine parvovirus IHHNV presence in or impact on farmed shrimp production

Journal of the World Aquaculture Society
The main purpose of this report is to provide hard evidence that the shrimp parvovirus IHHNV has not resulted “in significant consequences e.g. production losses, morbidity or mortality at a zone or country level” in Thailand since at least 2010. It also

Current status of infection with infectious hypodermal and hematopoietic necrosis virus (IHHNV) in the Peruvian and Ecuadorian shrimp industry. [PDF]

PLoS One, 2022
Infection with infectious hypodermal and hematopoietic necrosis virus (IHHNV) is a crustacean disease that caused large-scale mortality in Penaeus stylirostris, deformity and growth retardation in Penaeus vannamei and Penaeus monodon.

Shrimp genome sequence contains independent clusters of ancient and current Endogenous Viral Elements (EVE) of the parvovirus IHHNV. [PDF]

BMC Genomics, 2022
Shrimp have the ability to accommodate viruses in long term, persistent infections without signs of disease. Endogenous viral elements (EVE) play a role in this process probably via production of negative-sense Piwi-interacting RNA (piRNA)-like fragments.

Insights on Minimizing False Positives in IHHNV Detection: Experiences from Ecuador's <i>Penaeus vannamei</i> Aquaculture. [PDF]

Int J Mol Sci
Detection of infectious hypodermal and hematopoietic necrosis virus (IHHNV) in shrimp aquaculture is complicated by endogenous viral elements (EVEs) causing false positives in conventional PCR assays. This study analyzed 277 Penaeus vannamei samples from

Development and Evaluation of a Shrimp Virus (IHHNV)-Mediated Gene Transfer and Expression System for Shrimps. [PDF]

Int J Mol Sci
An efficient gene transfer and expression tool is lacking for shrimps and shrimp cells. To solve this, this study has developed a shrimp DNA virus-mediated gene transfer and expression system, consisting of insect Sf9 cells for viral packaging, the ...

Genome assembly of the Australian black tiger shrimp (Penaeus monodon) reveals a novel fragmented IHHNV EVE sequence. [PDF]

G3 (Bethesda), 2022
Shrimp are a valuable aquaculture species globally; however, disease remains a major hindrance to shrimp aquaculture sustainability and growth. Mechanisms mediated by endogenous viral elements have been proposed as a means by which shrimp that encounter ...

Dynamic integration and evolutionary trajectory of endogenous IHHNV elements in crustacean genomes. [PDF]

DNA Res
Endogenous viral elements (EVEs) serve as molecular fossils that record the ancient co-evolutionary arms race between viruses and their hosts. In this study, by analyzing 105 host crustacean genomes, we identified 252 infectious hypodermal and ...

Confirmatory test of active IHHNV infection in shrimp by immunohistochemistry and IHHNV-LongAmp PCR.

Journal of Fish Diseases, Volume 47, Issue 3, March 2024., 2023
The presence of endogenous viral elements (EVE) in the penaeid shrimp genome has been recently reported and suggested to be involved in the host recognition of viral invaders.

One-Pot RAA-CRISPR/Cas12a Assay for Rapid Detection of Infectious Hypodermal and Haematopoietic Necrosis Virus (IHHNV) in Shrimp Aquaculture. [PDF]

J Fish Dis
The infectious hypodermal and haematopoietic necrosis virus (IHHNV) represents a significant viral threat to global shrimp aquaculture, leading to considerable economic losses. In this study, we have developed a one-step, one-pot isothermal assay for the
