The determination of veterinary antibiotics in live animals and animal products
… in human medicine. The contributions of veterinary medicine and agriculture to antibiotic resistance are still being investigated.”1 Hence, there is pressure on analytical scientists to detect and confirm the presence of antimicrobials in foods of animal origin. The aminoglycosides and …

The effects and fate of selected veterinary antibiotics in two Missouri anaerobic swine lagoons
… of concern has emerged regarding the presence of antibiotics in the environment and the increase in antibiotic-resistant bacterial infections. This has prompted researchers to study the effects and fate of antibiotics in the environment. Little work has been conducted, however, on the effects and …

Degradation and transport of veterinary antibiotics and estrogens in a vegetated buffer strip system
Knowledge of veterinary antibiotic (VA) and estrogenic hormone persistence in soil is critical to understanding environmental risks associated with these potential contaminants. Understanding sorption and transport of the VAs sulfamethazine (SMZ) and lincomycin (LIN) and the estrogenic hormones …

Pleuromutilin and its Application Towards Bidentate Antibiotics: Triazoles, Linker Chemistry, and Serendipitous Discoveries
… (AMR) crisis. Classes of antibiotics continually face ineffectiveness as resistance mechanisms in microbes develop and propagate. The semi-synthetic derivatization of natural product antibiotics has provided many of our treatments, but new treatments are a constant …

Environmental Fate of Animal Manure-associated Antibiotics and Seed-coated Pesticide in Soils
… systems. The environmental persistence of veterinary antibiotics applied to agricultural fields during manure fertilization could lead to increased antibiotic resistance. New generation, neonicotinoid pesticides pose a threat to aquatic ecosystem health due high water mobility and increased …

Transport and fate of veterinary sulfonamide antibiotics in soil
Sulfonamide antibiotics is one group of important pharmaceuticals in the veterinary medicine market. Discharge of antibiotics from wastewater treatment plants lead to their presence in river and groundwater. In agricultural regions, application of animal manure on crop lands is a major …

Impact of Manure Land Management Practices on Manure Borne Antibiotic Resistant Elements (AREs) in Agroecosystems
… antimicrobials used in the U.S. are involved in veterinary medicine, primarily with livestock rearing. Animal manure land application integrates livestock farming and agroecosystems. This manure contains antibiotic resistant elements (AREs) (resistant bacteria, resistance genes, and veterinary …

Illuminating controls on solute and water transport in the critical zone
… to plots containing manure spiked with eight veterinary antibiotics with a range of mobility, and quantified transport to suction lysimeters (30 and 90 cm). We showed that low preferential flow (<20%) eliminates the influence of compound chemical properties and, contrary to conventional …

Impact of Manure Management Practices on the Environmental Fate of Antibiotics in Manure-Applied Fields
Antibiotics and antibiotic resistance genes from animal manure applied to soil as fertilizer are now among the most concerned contaminants in soil. The widespread use of antibiotics in livestock might amplify the risk of developing antibiotic resistance, causing once treatable diseases to turn …

Sorption Characteristics of Veterinary Ionophore Antibiotics Monensin and Lasalocid and Soil Clay Constituents Kaolinite, Illite and Montmorillonite
<p>Monensin and Lasalocid are veterinary ionophore antibiotics used for therapeutic and non-therapeutic treatment of livestock. Manure containing un-metabolized compounds is in turn used as beneficial amendment for agricultural crops, thus, these compounds may be available for transport through …
