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.

Trends in Veterinary Drug Residues in US Cattle: Analysing USDA Sampling Data. [PDF]

Vet Med Sci
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.
