Potential Antibacterial Activity of Marine Macroalgae against Pathogens Relevant for Aquaculture and Human Health

Journal of Pure and Applied Microbiology, 2017
The exploitation of macroalgal biomass, as a source of antibacterial drugs, would result into the valuable transformation of waste into an economic resource. Ethanol and water extracts or polysaccharides, from nine DNA-barcoded macroalgae (2 Chlorophyta,

Daphnia‐associated bacterial communities correlate with diet quantity, environmental conditions, and epidemic size across natural outbreaks

Limnology and Oceanography, Volume 70, Issue 8, Page 2053-2066, August 2025.
Abstract Zooplankton‐associated microbiomes play an important role for host health, and contribute to ecosystem processes such as nutrient cycling. Yet, few studies have assessed how environmental gradients and biotic interactions, including parasitism and diet, may shape the microbiome composition of wild zooplankton. Here, we analyzed the microbiomes

Binding of haemin by the fish pathogen Photobacterium damselae subsp. piscicida [PDF]

Diseases of Aquatic Organisms, 2002
Whole cells of virulent (DI 21 and B 51) and avirulent (ATCC 29690 and EPOY 8803-II) strains of Photobacterium damselae subsp. piscicida, grown under iron-supplemented or iron-restricted conditions, were able to bind haemin. Iron limitation resulted in an increased binding of haemin by DI 21, B 51 and ATCC 29690 cells but did not affect the haemin ...

Experimental Challenge of Chinook Salmon (Oncorhynchus tshawytscha) With Tenacibaculum maritimum and Tenacibaculum dicentrarchi Fulfils Koch's Postulates

Journal of Fish Diseases, Volume 48, Issue 6, June 2025.
ABSTRACT The bacterial skin disease tenacibaculosis, caused by Tenacibaculum species, affects numerous economically important marine fish, including salmonids. This study reports the ability of three Tenacibaculum maritimum strains, belonging to different molecular O‐AGC types, and a single Tenacibaculum dicentrarchi strain to induce tenacibaculosis in

A Novel Genomic Island Encodes Vibrioferrin Synthesis in the Marine Pathogen Photobacterium Damselae Subsp. Damselae

Microbial Pathogenesis
In this study, we identified and analyzed a novel genomic island (GI), named pddGI-1, located on chromosome II of certain strains of the marine pathogen Photobacterium damselae subsp. damselae (Pdd). This GI shares structural similarities with other GIs found in Vibrio species, such as the Vibrio seventh pandemic island-II (VSP-II) of V. cholerae.

Flatfish lesion detection based on part segmentation approach and lesion image generation

Journal of the World Aquaculture Society, Volume 56, Issue 3, June 2025.
Abstract The flatfish is a major farmed species consumed globally in large quantities. However, due to the densely populated farming environment, flatfish are susceptible to lesions and diseases, making early lesion detection crucial. Traditionally, lesions were detected through visual inspection, but observing large numbers of fish is challenging ...

Recent Advances in Functionalized Isocyanide Synthesis and Natural Products Containing the Isocyano Functional Group and Their Biological Properties

ChemistrySelect, Volume 10, Issue 16, April 25, 2025.
One important strategy to increase the versatility of isocyanides is to employ functionalized isocyanides. It should be mentioned that after being functionalized, isocyanides can precisely regulate their reactivity during a chemical reaction. Natural occurring isocyanides exhibit distinct biosynthetic pathways, and understanding these pathways sheds ...

Monitoring Fish Bacterial Pathogens of Wild Fish Species From the South China Sea by Applying Next‐Generation Sequencing on Gill Tissue

Journal of Fish Diseases, Volume 48, Issue 2, February 2025.
ABSTRACT The classic epidemiological triangle model of host—environment—pathogen is recently being reshaped into a tetrahedron, with the growing understanding of the importance of the microbiome in this array. The gills, being a gateway into the fish body, bearing an important role in fish homeostasis, host a complex microbiome that reflects the ...
