Multifaceted Role of Probiotics in Enhancing Health and Growth of Aquatic Animals: Mechanisms, Benefits, and Applications in Sustainable Aquaculture-A Review and Bibliometric Analysis. [PDF]

Aquac Nutr
Probiotics play a pivotal role in enhancing the health and growth of aquatic animals in aquaculture. These beneficial microorganisms contribute to improved digestion and nutrient absorption by producing digestive enzymes such as amylases, proteases, and lipases, besides providing essential nutrients.

Immersion challenge of three salmonid species (family Salmonidae) with three multilocus sequence typing variants of Flavobacterium psychrophilum provides evidence of differential host specificity. [PDF]

J Fish Dis
Abstract Bacterial coldwater disease (BCWD), caused by Flavobacterium psychrophilum, results in significant losses among multiple salmonid (family Salmonidae) species. Molecular epidemiology and serotyping studies have suggested that some variants are host specific; however, these associations have not been evaluated by cross‐challenging fish species ...

Complete genome sequence and potential pathogenic assessment of Flavobacterium plurextorum RSG-18 isolated from the gut of Schlegel's black rockfish, Sebastes schlegelii. [PDF]

Environ Microbiol Rep
The complete genome was constructed to investigate the genetic potential of RSG‐18 for pathogenicity. Comparative genome analysis with other well‐known flavobacterial fish pathogens revealed that RSG‐18 possesses putative virulence genes associated with protein degradation and resistance to fish phagocytes, as well as various types of secretion systems

Extracellular Vesicles From Xylella fastidiosa Carry sRNAs and Genomic Islands, Suggesting Roles in Recipient Cells. [PDF]

J Extracell Vesicles
ABSTRACT Xylella fastidiosa (Xf) is a Gram‐negative bacterial plant pathogen responsible for severe diseases in a variety of economically important crops. A critical aspect of its virulence is the production of extracellular vesicles (EVs). In this study, we discovered that DNA‐binding proteins and nonribosomal RNA‐binding proteins are abundant in the ...

Dual RNA-Seq of Flavobacterium psychrophilum and Its Outer Membrane Vesicles Distinguishes Genes Associated with Susceptibility to Bacterial Cold-Water Disease in Rainbow Trout (Oncorhynchus mykiss)

Pathogens, 2023
Flavobacterium psychrophilum (Fp), the causative agent of Bacterial Cold-Water disease in salmonids, causes substantial losses in aquaculture. Bacterial outer membrane vesicles (OMVs) contain several virulence factors, enzymes, toxins, and nucleic acids ...

Skin bacteria of rainbow trout antagonistic to the fish pathogen Flavobacterium psychrophilum

Scientific Reports, 2021
Rainbow trout fry syndrome (RTFS) and bacterial coldwater disease (BCWD) is a globally distributed freshwater fish disease caused by Flavobacterium psychrophilum. In spite of its importance, an effective vaccine is not still available.

A review of bacterial disease outbreaks in rainbow trout (Oncorhynchus mykiss) reported from 2010 to 2022. [PDF]

J Fish Dis
Abstract Outbreaks of bacterial infections in aquaculture have emerged as significant threats to the sustainable production of rainbow trout (Oncorhynchus mykiss) worldwide. Understanding the dynamics of these outbreaks and the bacteria involved is crucial for implementing effective management strategies. This comprehensive review presents an update on

Ultraviolet light differentially reduces viability of fish‐ and fish farm‐associated flavobacteria (families Flavobacteriaceae and Weeksellaceae)

North American Journal of Aquaculture, Volume 85, Issue 4, Page 311-323, October 2023., 2023
Abstract Objective Globally, flavobacteria (family Flavobacteriaceae and Weeksellaceae) are leading causes of disease‐related losses in fish‐farms and hatcheries. One route flavobacteria gain access to aquaculture facilities is via source water.

Closing the gap between science and management of cold‐water refuges in rivers and streams

Global Change Biology, Volume 29, Issue 19, Page 5482-5508, October 2023., 2023
We review current understanding of cold‐water refuges, identify gaps between science and management, and evaluate policies aimed at protecting thermally sensitive species. Linking the science and management of cold‐water refuges requires interdisciplinary approaches to understanding complex interactions among physical, ecological, social, and cultural ...

Detection and virulence of Lactococcus garvieae and L. petauri from four lakes in southern California

Journal of Aquatic Animal Health, Volume 35, Issue 3, Page 187-198, September 2023., 2023
Abstract Objective The first objective of the study aimed to detect the presence of Lactococcus petauri, L. garvieae, and L. formosensis in fish (n = 359) and environmental (n = 161) samples from four lakes near an affected fish farm in California during an outbreak in 2020. The second objective was to compare the virulence of the Lactococcus spp.
