POTENCY OF VIBRIO ISOLATES FOR BIOCONTROL OF VIBRIOSIS IN TIGER SHRIMP (PENAEUS MONODON) LARVAE

Biotropia: The Southeast Asian Journal of Tropical Biology, 2011
This study was carried out to obtain Vibrio isolates able to function as biocontrol of vibriosis in shrimp hatchery. Thirty one Vibrio isolates were isolated from tiger shrimp larvae and hatchery environments, i.e.

Nanotechnology‐Based Immunostimulants in Aquaculture: Mechanisms, Advances and Practical Applications

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Nano‐immunostimulants improve fish health through targeted and controlled delivery of immunostimulatory compounds. Biodegradable polymeric and lipid‐based nanocarriers enhance immune responses, bioavailability and disease resistance while reducing antibiotic dependence and environmental impact.

Exploring Antibacterial Activity of Fish Protein Hydrolysate In Vitro Against Vibrio Strains and Disease Resistance to V. harveyi in Turbot (Scophthalmus maximus)

Aquaculture Nutrition
This study was to investigate the in vitro antimicrobial activity of fish protein hydrolysate (FPH) against Vibrio harveyi, V. anguillarum, and V. scophthalmi, as well as the nonspecific immunity, intestinal microbiota, and disease resistance to V ...

A Single‐Nucleotide Substitution Generates a de Novo Promoter That Activates a Latent Metabolic Bypass in Escherichia coli

Molecular Microbiology, Volume 126, Issue 3, Page 244-251, September 2026.
A chromosomal mutation allows bypass of deletion of the Escherichia coli fabH gene. The bypass results from creation of a new promoter that drives increased madA transcription, resulting in increased synthesis of acetyl‐acyl carrier protein by decarboxylation of malonyl‐acyl carrier protein.

Nutritional Value of Biofloc Meal for White Cachama (Piaractus orinoquensis): Effects of Inclusion Level on Digestibility, Growth Performance, and Protein Retention

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Biofloc technology (BFT) offers a sustainable aquaculture strategy; however, the value of its byproduct, biofloc meal (BFM), as a feed ingredient requires validation for key species. This study evaluated the use of BFM from a tilapia–molasses system as a feed ingredient for white cachama (Piaractus orinoquensis) juveniles.

Transcriptional regulation of lux genes transferred into Vibrio harveyi

Journal of Bacteriology, 1990
Past work has shown that transformed Escherichia coli is not a suitable vehicle for studying the expression and regulation of the cloned luminescence (lux) genes of Vibrio harveyi. Therefore, we have used a conjugative system to transfer lux genes cloned into E. coli back into V. harveyi, where they can be studied in the parental organism.

Tracing Genomic Divergence of Vibrio Bacteria in the Harveyi Clade [PDF]

Journal of Bacteriology, 2018
To investigate the mechanisms underlying speciation in the genus Vibrio , we provided a well-assembled reference of genomes and performed systematic genomic comparisons among three evolutionarily closely related species.

Epinephrine Enhances Virulence‐Associated Traits of Vibrio alginolyticus and Increases Mortality in Sciaenops ocellatus (Linnaeus, 1766)

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Stress hormones released during aquaculture handling and environmental disturbances can influence host–pathogen interactions, yet their effects on marine bacterial pathogens remain largely unexplored. This study examined how the stress hormone epinephrine affects the virulence of Vibrio alginolyticus isolated from diseased red drum (Sciaenops ...

Protective effect of mangrove (Rhizophora apiculata) leaves extract in shrimp (Penaeus monodon) larvae against bio-luminescent disease-causing Vibrio harveyi bacteria

Spanish Journal of Agricultural Research, 2018
Application of chemicals for monitoring if Vibrio outbreaks can enhance resistance in mangrove (Rhizophora apiculata) leaves extract was tested against bioluminescence disease-causing Vibrio harveyi bacteria.
