There is an increasing number of emerging infectious agents, although not zoonotic, that affect farmed tilapines worldwide. Most recently, the emergence of a new virus, tilapia lake virus (TiLV), has diverted global attention to it while little or no research is being done on the other viruses of possible equal importance. These other viruses have reportedly been associated with relatively high mortalities (20-100%) in several cases of natural disease outbreaks or laboratory challenges. The objective of this review is to highlight viral infections of tilapines that may have been neglected by the scientific community but are also requiring systematic investigation. The viral infections in this review include infectious pancreatic necrosis virus (IPNV, Aquabirnavirus), nervous necrosis virus (VNN, Betanodavirus), tilapia larvae encephalitis virus (TLEV, Herpesvirus), and the Iridovirus infections namely Bohle iridovirus (BIV, Ranavirus) infectious spleen and kidney necrosis virus (ISKNV, Megalocytivirus), Lymphocystivirus and another Iridovirus-like infection. This review summarizes current scientific knowledge on viral infections that affect tilapines and highlights diagnosis methods for disease surveillance and discusses the future visions for disease control.

CRISPR-based platform for rapid, sensitive and field-deployable detection of scale drop disease virus in Asian sea bass (Lates calcarifer)

Thanwarat Sukonta, Saengchan Senapin, Watcharachai Meemetta, Thawatchai Chaijarasphong

Summary: A novel detection platform for SDDV based on CRISPR-Cas12a and recombinase polymerase amplification technology has been developed, showing high sensitivity and specificity for rapid and accurate diagnosis of SDDV. This user-friendly method can be completed within an hour at room temperature, potentially serving as a valuable tool for combating large-scale epidemics in fish farming communities.

Autogenous vaccination in aquaculture: A locally enabled solution towards reduction of the global antimicrobial resistance problem

Andrew C. Barnes, Oleksandra Silayeva, Matt Landos, Ha Thanh Dong, Angela Lusiastuti, Le Hong Phuoc, Jerome Delamare-Deboutteville

Summary: Antimicrobial resistance is a global crisis, especially in aquaculture where antibiotics are often used without proper information and record-keeping. Vaccination with autogenous vaccines may be a cost-effective solution to reduce antibiotic use, particularly in low- and middle-income countries with limited veterinary support.

Impacts of oxygen and ozone nanobubbles on bacteriophage in aquaculture system

Le Thanh Dien, Nguyen Vu Linh, Thao Thu Mai, Saengchan Senapin, Sophie St-Hilaire, Channarong Rodkhum, Ha Thanh Dong

Summary: Injection of ozone nanobubbles into water reduces bacterial load, improves dissolved oxygen, and modulates the fish innate immune system. This study investigates the effect of oxygen and ozone nanobubbles on a specific phage and finds that ozone nanobubbles can eradicate the phage while improving its adherence to fish body surfaces and penetration into internal organs. The use of ozone nanobubbles shows potential in reducing viral load in aquaculture.

Comparative Genomics of a Polyvalent Escherichia-Salmonella Phage fp01 and In Silico Analysis of Its Receptor Binding Protein and Conserved Enterobacteriaceae Phage Receptor

Ignacio Vasquez, Julio Retamales, Barbara Parra, Vimbai Machimbirike, James Robeson, Javier Santander

Summary: In this study, we sequenced and described the complete genome of the polyvalent phage fp01, which has 109,515 bp and 158 coding sequences (CDSs). The phage fp01 has genes with high similarity to Escherichia coli, Salmonella enterica, and Shigella sp. phages. The receptor-binding protein gp108 was identified as potentially responsible for fp01 polyvalent characteristics.

Comparative Genomic Analysis of Virulent Vibrio (Listonella) anguillarum Serotypes Revealed Genetic Diversity and Genomic Signatures in the O-Antigen Biosynthesis Gene Cluster

Vimbai Irene Machimbirike, Ignacio Vasquez, Trung Cao, Joy Chukwu-Osazuwa, Oluwatoyin Onireti, Cristopher Segovia, Pongsak Khunrae, Triwit Rattanarojpong, Marije Booman, Simon Jones, Manuel Soto-Davila, Brian Dixon, Javier Santander

Summary: This study investigates the genetic differences and evolution of the most common fish pathogen Vibrio anguillarum serotype O1. The O1 strain has two chromosomes and two typical plasmids. Furthermore, the O1 strain displays resistance to colistin sulphate, which differs from the O2 serotype and may be attributed to the ugd gene. The study also reveals that the genetic heterogeneity in the O-antigen biosynthesis gene cluster is characterized by the absence or presence of unique genes, which could result in differences in immune evasion mechanisms among serotypes.

Immunological response of 35 and 42 days old Asian seabass (Lates calcarifer, Bloch 1790) fry following immersion immunization with Streptococcus iniae heat-killed vaccine

Nguyen Tien Vinh, Ha Thanh Dong, Nguyen Giang Thu Lan, Pakkakul Sangsuriya, Krishna R. Salin, Satid Chatchaiphan, Saengchan Senapin

Summary: In this study, the immune responses of Asian seabass fry at 35 and 42 days post-hatching to a heat-killed Streptococcus iniae vaccine were investigated. It was found that fish at both stages could produce specific antibodies against the pathogen, with the 42-day fry showing a faster response. These findings suggest that early vaccination of Asian seabass fry between 35 and 42 days post-hatching is feasible.

Diet-egg relationships and equilibration of fatty acids in eggs of southern flounder, Paralichthys lethostigma

Hunter S. Bailey, Ashley N. Fincannon, Lee A. Fuiman

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
