“…campbellii is a pernicious pathogen in aquaculture, affecting farm stocks of fish, shrimps and mollusks worldwide (Austin and Zhang, 2006 ; Haldar et al, 2011 ; Wang et al, 2015 ). Diseases caused by V. campbellii include skin ulcers, vasculitis, gastrointestinal disorders and eye lesions in fish (Austin and Zhang, 2006 ; Shen et al, 2017 ) and the so-called “luminescent vibriosis” in crustaceans and mollusks, often involving mass mortality and extensive economic loss (Travers et al, 2009 ; Darshanee Ruwandeepika et al, 2012 ; Lio-Po, 2016 ). This disease owes its name to the bioluminescence displayed by its causative agents, primarily V .…”

Vibrio campbellii is a major pathogen in aquaculture. It is a causative agent of the so-called “luminescent vibriosis,” a life-threatening condition caused by bioluminescent Vibrio spp. that often involves mass mortality of farmed shrimps. The emergence of multidrug resistant Vibrio strains raises a concern and poses a challenge for the treatment of this infection in the coming years. Inhibition of bacterial cell-to-cell communication or quorum sensing (QS) has been proposed as an alternative to antibiotic therapies. Aiming to identify novel QS disruptors, the 9H-fluroen-9yl vinyl ether derivative SAM461 was found to thwart V. campbellii bioluminescence, a QS-regulated phenotype. Phenotypic and gene expression analyses revealed, however, that the mode of action of SAM461 was unrelated to QS inhibition. Further evaluation with purified Vibrio fischeri and NanoLuc luciferases revealed enzymatic inhibition at micromolar concentrations. In silico analysis by molecular docking suggested binding of SAM461 in the active site cavities of both luciferase enzymes. Subsequent in vivo testing of SAM461 with gnotobiotic Artemia franciscana nauplii demonstrated naupliar protection against V. campbellii infection at low micromolar concentrations. Taken together, these findings suggest that suppression of luciferase activity could constitute a novel paradigm in the development of alternative anti-infective chemotherapies against luminescent vibriosis, and pave the ground for the chemical synthesis and biological characterization of derivatives with promising antimicrobial prospects.

“…Polyculture between shrimp and tilapia has been applied in many countries, including Brazil (Junior et al, 2012), Philippines , Thailand , and Mexico (Hernández-Barraza et al, 2012;. Several publications have demonstrated that this combination results in a positive interaction during grow out, and that adding tilapia to shrimp ponds can significantly reduce shrimp disease and mortality (Erwiantono et al, 2020;Jaspe & Caipang, 2011;Lio-Po, 2017;.…”

Indonesia is an archipelago state that consists of thousand islands, and around 70% of the area is covered with water. With this advantage, Indonesia has become the third major world aquaculture producer (FAO, 2022). Shrimp, tilapia and seaweeds are the main products contributing to the increase of gross domestic product (GDP), gross regional domestic product (GRDP) and the volume of national aquaculture production from 2010 to 2018 (Oktopura et al., 2020). The Coastal environment offers a huge potential area for aquaculture, nationally involving more than 800.000 brackish water farmers. Total shrimp production was 0.88 million ton in 2022 of which 27.1% was exported, only second to tilapia (1.17 million ton), representing an export value of around 2.04 billion US dollars (MMAF, 2022). With strong demand and high prices, shrimp farming has become the most valuable aquaculture sector, and this encouraged shrimp farmers to increase their production.However, a combination of poor water management, increasing density and high levels of commercial feed during intensification has caused serious land and environmental degradation. Disease outbreaks have caused repeated farming failures resulting in many shrimp farmers suffering from financial problems and quitting shrimp farming altogether. Alternative species for shrimp farmingShifting to other species has been a commonly used strategy to minimize economic losses since shrimp farming has become a high-risk industry. Shrimp and milkfish have traditionally dominated brackish water pond production . Grouper and seabass are also produced in brackish water, but in intensive, tank based, systems because these species need specific requirements to grow normally. Smallholder farmers cannot access the financial and technical resources required to farm these two species.Farming tilapia in brackish water is becoming more preferred in the coastal areas. To date, the majority of tilapia are produced in fresh water, and brackish water farming contributes only 3.3% of total production. Fisheries extension services in Central Java have recently reported that the number of tilapia farmers in brackish water ponds is increasing. The rapid growth of tilapia in brackish water has also encouraged many milkfish farmers to shift to tilapia farming, particularly in East and Central Java. The selling price for tilapia in many

Aims This study describes the physicochemical and genomic characterization of phage vB_Vc_SrVc9 and its potential for phage therapy application against a pathogenic Vibrio campbellii strain. Methods and Results A lytic phage vB_Vc_SrVc9 against V. campbellii was isolated from shrimp farm sediment, and characterized physicochemical and genomically. The use of vB_Vc_SrVc9 phage increased the survival in brine shrimp Artemia franciscana and reduced presumptive V. campbellii to nondetectable numbers. Genomic analysis showed a genome with a single contig of 43·15 kb, with 49 predicted genes and no tRNAs, capable of recognizing and generating complete inhibition zones of three Vibrio sp. Conclusions To our knowledge vB_Vc_SrVc9 is a lytic phage that could be used against Vibrio infections, reducing vibrio presence without any apparent impact over the natural microbiota at the family level in 28 libraries tested. Significance and Impact of the Study vB_Vc_SrVC9 is a novel phage and ecofriendly alternative for therapeutic applications and biotechnological purposes because is stable at different environmental conditions, has the potential to eliminate several strains, and has a short latent period with a good burst size. Therefore, the use of phages, which are natural killers of bacteria, represents a promising strategy to reduce the mortality of farmed organisms caused by pathogenic bacteria.
