Cloning of IRAK1 and its upregulation in symptomatic mandarin fish infected with ISKNV

Biochemical and Biophysical Research Communications, 2009
Interleukin-1 receptor activated kinases (IRAKs) play crucial roles in the Toll-like receptor (TLR) mediated signal transduction pathways that control host innate immune responses. Here we report the cloning of an IRAK1 cDNA (named ScIRAK1) from the mandarin fish.

Partial validation of a TaqMan quantitative polymerase chain reaction for the detection of the three genotypes of Infectious spleen and kidney necrosis virus

PLoS ONE, 2023
Megalocytiviruses (MCVs) are double-stranded DNA viruses known to infect important freshwater and marine fish species in the aquaculture, food, and ornamental fish industries worldwide.

Molecular confirmation of infectious spleen and kidney necrosis virus (ISKNV) in farmed and imported ornamental fish in Australia [PDF]

Diseases of Aquatic Organisms, 2015
Viruses of the genus Megalocytivirus have not been detected in wild populations of fish in Australia but circulate in imported ornamental fish. In 2012, detection of a megalocytivirus in healthy platys Xiphophorus maculatus was reported from a farm in Australia during surveillance testing as part of a research project undertaken at the University of ...

First detection of infectious spleen and kidney necrosis virus (ISKNV) associated with massive mortalities in farmed tilapia in Africa [PDF]

Transboundary and Emerging Diseases, 2019
Summary In late 2018, unusual patterns of very high mortality (>50% production) were reported in intensive tilapia cage culture systems across Lake Volta in Ghana. Samples of fish and fry were collected and analysed from two affected farms between October 2018 and February 2019.

Potentially new emerging diseases on two species of Indonesian freshwater aquaculture: giant gourami (Osphronemus gourami) and Asian catfish (Pangasius hypophthalmus) [PDF]

E3S Web of Conferences, 2021
Disease outbreaks and mortality in giant gourami and Asian catfish (pangasius) culture have been frequently reported during the last decade. Etiological agents of the disease have remained unknown, so it is needed to explore epidemiological studies to ...

The Role of Gut Microbiota in Fish Viral Infection: Mechanisms and Microbiota-Targeted Interventions. [PDF]

Aquac Nutr
Viral diseases represent one of the major threats to the global aquaculture industry. In recent years, the relationship between gut microbiota and viral infections in fish has garnered increasing attention. The gut microbiota contributes critically to fish health and is involved in antiviral defense through immune regulation, secretion of microbial ...

Infectious spleen and kidney necrosis virus induces the reactive oxidative species/Nrf2-mediated oxidative stress response for the regulation of mitochondrion-mediated Bax/Bak cell death signals in GF-1 cells

Frontiers in Microbiology, 2022
Infectious spleen and kidney necrosis virus (ISKNV) infections can trigger host cell death and are correlated with viral replication; however, they have rarely been considered in terms of the host organelle involvement.

First report of Iridovirus (ISKNV) infection in Israeli mariculture gilthead sea bream (Sparus aurata) at the Mediterranean Sea [PDF]

Israeli Journal of Aquaculture - Bamidgeh, 2021
Megalocytiviruses have caused mass mortalities in various farmed fish species, both edible and ornamental. Infectious spleen and kidney necrosis virus (ISKNV) belongs to this family of viruses and induces lethal diseases in cultured fish. Here, we publish the first report describing this epizootic virus affecting the sea bream (Sparus aurata) in the ...

The viral TRAF protein (ORF111L) from infectious spleen and kidney necrosis virus interacts with TRADD and induces caspase 8-mediated apoptosis.

PLoS ONE, 2012
Infectious spleen and kidney necrosis virus (ISKNV) is the type species of the Megalocytivirus genus of the Iridoviridae family. It causes a serious and potentially pandemic disease in wild and cultured fishes.

Outbreak investigation attributes Infectious spleen and kidney necrosis virus as a necessary cause of a mortality epidemic in farmed grouper (Epinephelus spp.) in Bali, Indonesia

Aquaculture Reports, 2021
In 2016, famers reported mass mortality events in hybrid grouper within 2–4 weeks following transfer to sea cages on the northern coast of Bali. The objective was to obtain an aetiological diagnosis using a broad range of traditional and emerging ...
