Decoding the Black Box of Fish Vaccines Efficacy in Basic and Applied Contexts
ABSTRACT Vaccines are the frontline defense in aquaculture, yet predicting their real‐world performance remains a tricky puzzle. Unlike terrestrial veterinary vaccines, fish vaccines largely operate through “Black Box” processes, where we observe the outcomes but rarely understand the underlying immune mechanisms. Laboratory trials, though informative,

Toxicity of extracellular products of Vibrio anguillarum.
Vibrio anguillarum produced heat labile(70°C, 10 min) exotoxin lethal to goldfish, Japanese eel, ayu and mouse when injected. The extracellular products(ECP)from cellophane plate cultures(nutrient agar or BHI agar)at 20°Cor 25°Cfor 18-36 h were toxic, but not in 24 h BHI broth culture at 25°C.

HlyU Is a Positive Regulator of Hemolysin Expression in Vibrio anguillarum [PDF]
ABSTRACT The two hemolysin gene clusters previously identified in Vibrio anguillarum , the vah1 cluster and the rtxACHBDE cluster, are responsible for the hemolytic and cytotoxic activities of V. anguillarum in fish.

ABSTRACT In this study, we investigated the immunomodulatory effects of St. John's Wort (Hypericum perforatum) oil on the growth performance, immune responses and resistance against Lactococcus garvieae in rainbow trout (Oncorhynchus mykiss). The plant oil was incorporated into feeds at concentrations of 1, 3, and 5 g kg−1, designated as K1, K3, and K5,

ABSTRACT Spring viremia of carp virus (SVCV) is a contagious pathogen associated with significant mortality and economic losses in freshwater aquaculture. Although reverse transcription quantitative PCR (RT‐qPCR) enables rapid detection, it does not distinguish between infectious and non‐infectious viral particles, which may lead to overestimation of ...

Comparative Serology of the Marine Fish Pathogen Vibrio anguillarum [PDF]
The different serotyping systems, based on thermostable O antigens, reported for Vibrio anguillarum and V. ordalii were compared by quantitative agglutination, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and subsequent silver staining or Western blotting (immunoblotting) of purified lipopolysaccharide (LPS), using polyclonal rabbit ...

Abstract Fish vaccination has been practiced globally for several decades and is increasingly recognized as a cornerstone of sustainable disease management in aquaculture, offering an effective alternative to antibiotic and chemotherapeutic use. This PRISMA‐ScR guided Scoping Review synthesized evidence from 173 peer‐reviewed studies and reports to ...

An extracellular protease produced by Vibrio anguillarum.
The toxicity of extracellular products (ECP) of Vibrlo anguillarum proved to consist in a protease. The extracellular protease was purified by precipitation with ammonium sulfate and gel filtration, and it showed the following characteristics:1. The LD ??

Serum Antibody against Vibrio anguillarum in cultured Rainbow Trout (Oncorhynchus mykiss)
In order to determine the concentration of the antibodies against the pathogenic Vibrio anguillarum, three hundred blood samples were taken from 9-12 month old cultured rainbow trout (Oncorhynchus mykiss) in 4 farms in the north and west region of Fars ...
