First Detection of Lactococcus formosensis subsp. formosensis in Rainbow Trout (Oncorhynchus mykiss) in Europe

Journal of Fish Diseases, Volume 49, Issue 4, April 2026.
ABSTRACT Lactococcus garvieae, Lactococcus petauri and Lactococcus formosensis are etiological agents of piscine lactococcosis, a disease reported in Italy since the early 1990s and linked to significant aquaculture losses. To the best of our knowledge, this study reports the first detection of L. formosensis subsp. formosensis in farmed rainbow trout (

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on Hereditary Fructose Intolerance (HFI), or aldolase B deficiency, and fructose malabsorption (intestinal fructose intolerance)

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Hereditary Fructose Intolerance (HFI), also known as aldolase B deficiency, is an inherited metabolic disorder caused by the deficiency of that enzyme, which participates in the fructose metabolism in the liver, kidneys and small intestine. Aldolase B deficiency brings about the accumulation of fructose‐1‐phosphate in these organs, which can ...

Untargeted Profiling of Fungicide Resistance‐Related Extracellular Metabolites of Phytophthora infestans Using Two‐Dimensional Gas Chromatography Coupled With Time‐of‐Flight Mass Spectrometry

Plant Pathology, Volume 75, Issue 2, March/April 2026.
Untargeted extracellular metabolite profiling of fungicide‐resistant and ‐sensitive strains of Phytophthora infestans revealed that several pathways were regulated to develop fungicide resistance, and the resistant strain showed a stronger (time‐ and dose‐dependent) metabolic response under fungicide exposure, and resistance was associated with a ...

α-d-Tagatopyranose

Acta Crystallographica Section E, 2009
The title compound, C6H12O6, also known as d-Tagatose, occurs in its furanose and pyranose forms in solution, but only the α-pyranose form crystallizes out. In the crystal, the molecules form hydrogen bonded chains propagating in [100] linked by
