Revisiting Old Ionophore Lasalocid as a Novel Inhibitor of Multiple Toxins
Toxins, 2020 The ionophore lasalocid is widely used as a veterinary drug against coccidiosis. We found recently that lasalocid protects cells from two unrelated bacterial toxins, the cytotoxic necrotizing factor-1 (CNF1) from Escherichia.

Lasalocid awareness and sampling in Scotland [PDF]
International Journal of Environmental Health Research, 2010 Lasalocid is an ionophore antibiotic extensively used as a coccidiostat in poultry production. Lasalocid should not be fed to egg-laying hens as it accumulates in the eggs, and residues have often been found in eggs. Other ionophores are toxic to humans, but the exact level of lasalocid toxicity to humans has not been established. Approximately 250 egg

Spectroscopic, Spectrometric and Computational Studies of New Lasalocid Derivatives and Their Complexes with Selected Metal Cations [PDF]
Molecules, 2023 A series of five esters of lasalocid with neopentyl alcohol (LasNeo), geraniol (LasGeran), 2-ethylhexanol (LasEtHex), eicosanol (LasEico) and vanillyl alcohol (LasVanil) were synthesized and studied by NMR, FT-IR and ESI-MS.

Trends in Veterinary Drug Residues in US Cattle: Analysing USDA Sampling Data [PDF]
Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.National US residue monitoring data (2021–2023) were analysed to characterise veterinary drug residue detections in cattle. Detection patterns varied by cattle type, with dairy cows accounting for the highest number of detections and a consistent group of commonly used drugs responsible for most violative and non‐violative findings.

New Hydrophilic Derivatives of Lasalocid and Their Complexes with Selected Metal Cations [PDF]
Molecules, 2023 Two new esters of lasalocid, that are more hydrophilic, with glucose (LasGlu) and xylitol (LasX), have been synthesized, and their complexation of monovalent cations has been studied by various spectrometric and spectroscopic methods, such as ESI mass ...

Structural Basis of Sequential Enantioselective Epoxidation by a Flavin‐Dependent Monooxygenase in Lasalocid A Biosynthesis [PDF]
Angewandte Chemie, Volume 137, Issue 24, June 10, 2025.Lsd18 is a flavin‐dependent monooxygenase from Streptomyces lasalocidi that performs two enantioselective epoxidations during lasalocid A biosynthesis. X‐ray crystal structures of Lsd18 bound to a substrate and product analogue illuminate how this enzyme performs multiple epoxidations on the same substrate molecule and how it controls stereoselectivity.

Screening of Chemical Residues and Antimicrobial Resistance in Dehydrated Chicken Feet Intended as Dog Treats: A Pilot Study [PDF]
Veterinary Medicine International, Volume 2026, Issue 1, 2026.The pet population is steadily increasing worldwide, and treats, which account for approximately 15% of the pet food market, are the fastest‐growing segment of the pet food industry. However, the widespread use of antimicrobials in poultry farms may pose a direct risk to pets’ health, leading to the emergence of antimicrobial resistance.

Assessment of the application for modification of the terms of the authorisation of the feed additive consisting of Bacillus velezensis ATCC PTA‐6737 (PB6) for all pigs, all poultry species for fattening or reared for laying/breeding, laying hens, minor poultry species for laying and ornamental birds (Kemin Europa N.V.) [PDF]
EFSA Journal, Volume 24, Issue 5, May 2026.Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the preparation consisting of viable spores of Bacillus velezensis ATCC PTA‐6737 (tradename PB6). PB6 is currently authorised for use as a zootechnical additive (functional group: gut flora stabilisers) for all poultry
