Abnormalities in red blood cell production and pathogenesis of anemia in the progression of rock bream iridovirus (RBIV) [PDF]

Virus Research
Rock bream iridovirus (RBIV), belonging to Megalocytivirus, causes severe mortality in rock bream. Almost all deaths associated with RBIV are accompanied by splenic enlargement and anemia.

Risk of Spread of Megalocytivirus pagrus1 (Infectious Spleen and Kidney Necrosis Virus) From Frozen Fillets. [PDF]

J Fish Dis
ABSTRACT Infectious spleen and kidney necrosis virus (ISKNV) is a significant threat to global aquatic food security by causing large‐scale mortality in the aquaculture of tilapia (Oreochromis niloticus) and mandarin fish (Siniperca chuatsi). ISKNV is a genogroup of Megalocytivirus pagrus1, along with RSIV and TRBIV, and their recent listing as WOAH ...

Genomic Analysis of Megalocytivirus Genomes Reveals Widespread Recombination. [PDF]

Genome Biol Evol
Abstract Megalocytiviruses are pathogens of global significance that can lead to substantial economic losses in aquaculture. Recombination among megalocytiviruses is typically assumed to be rare, although it has been relatively understudied.

Microbiome and Pathobiome Characterization in Farmed Barramundi (Lates calcarifer) During and Post Scale Drop Disease Outbreaks. [PDF]

J Fish Dis
ABSTRACT Large‐scale double‐digest RAD sequencing (ddRADseq) datasets generated for genotyping are increasingly available in aquaculture, yet their unmapped reads remain largely unexplored for pathogen surveillance. Here, we evaluated the utility and limitations of repurposing unmapped ddRADseq reads to examine pathogen‐associated and disease ...

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 ...

Divergent survival and viral shedding patterns of red sea bream iridovirus in black sea bream and Japanese sea bass. [PDF]

J Fish Biol
Abstract In open marine aquaculture, rearing diverse fish species in adjacent net pens facilitates the waterborne spread of red sea bream iridovirus (RSIV). This study systematically evaluated the horizontal transmission dynamics of RSIV in black sea bream (BSB, Acanthopagrus schlegelii) and Japanese sea bass (JS, Lateolabrax japonicus) under immersion

Improved multiplex PCR method for the detection of diverse Megalocytivirus in the Korea [PDF]

, 2021
Megalocytivirus is a genus of piscine viruses that belongs to the Iridoviridae family, and this family comprises red seabream iridovirus (RSIV), turbot reddish body iridovirus (TRBIV), and infectious spleen and kidney necrosis virus. RSIV causes high mortality and economic losses in the rock bream (Oplegnathus fasciatus) Korean aquaculture industry ...

Improving tilapia biosecurity through a value chain approach

Reviews in Aquaculture, Volume 15, Issue S1, Page 57-91, February 2023., 2023
Abstract Tilapia aquaculture is a major source of animal protein, with global production reaching over 6 million tonnes in 2020. The rapid growth of the tilapia sector has led to a number of emerging disease threats and subsequent production losses. Risk analysis can provide a targeted approach for improving biosecurity in the tilapia sector.
