Exposure of a Tropical Soil to mg/kg of Oxytetracycline Elicits Hormetic Responses in the Catabolic Activities of its Microbial Community
Many farmers in developing countries protect their crops with oxytetracycline and fertilize their farmlands with manure from animals that received this drug as growth promoter. In this study, a tropical soil was exposed ...
Residue depletion of oxytetracycline (OTC) and 4-epi-oxytetracycline (4-epi-OTC) in broiler chicken’s claws by liquid chromatography-tandem mass spectrometry (LC-MS/MS)
(Taylor and Francis Ltd., 2017)
© 2016 Informa UK Limited, trading as Taylor & Francis Group. Antibiotics are widely used in poultry production for the treatment of bacterial diseases. However, residues may remain in products and by-products destined for ...
UV-vis, IR and 1H NMR spectroscopic studies and characterization of ionic-pair crystal violet-oxytetracycline
The present study shows the formation and characterization of the ionic-pair between the antibiotic oxytetracycline and the dye crystal violet in ammonia solution pH 9.0 ± 0.2 extracted into chloroform. The characterization ...
Pharmacokinetic study of long-acting oxytetracycline in cows. Estudio cinético de oxitetraciclina de larga acción en bovinos de Iechería
Pharmacokinetics of a long-acting formula of oxytetracycline (OTC) in one formulation of dymetylacetomide, was studied in seven-cows after i.m. administration (20 mg/kg of body weight). Serum OTC concentration was measured ...
Extraction and Determination of Oxytetracycline Hydrochloride and Oxolinic Acid in Fish Feed by Derivative Spectrophotometry of First Order
In this work is proposed the extraction and determination of oxytetracycline (OTC) and oxolinic acid (OA) in fish feed by first-derivative spectrophotometry. The extractions are carried out by parallel modality, where OTC ...

A Critical Review of Properties and Analytical Methods for the Determination of Oxytetracyline in Biological and Pharmaceutical Matrices
(Taylor & Francis Inc, 2017-01-01)
Antibiotics have an unquestionable importance in the treatment of many infections. Oxytetracycline is an antibiotic belonging to the class of tetracyclines, available for use in human and veterinary medicine. Development ...
Diversity and antimicrobial susceptibility of oxytetracycline-resistant isolates of Stenotrophomonas sp. and Serratia sp. associated with Costa Rican crops
Aims: to ameliorate the identification, evaluate the diversity, and determine the antimicrobial sensitivity of 19 oxytetracycline-resistant isolates of Stenotrophomonas sp. and Serratia sp. associated with Costa Rican ...
Determination of Oxytetracycline from Salmon Muscle and Skin by Derivative Spectrophotometry
A method was developed for the identification and quantification of oxytetracycline residues present in salmon muscle and skin using UV-Vis derivative spectrophotometry. With this method, it was possible to reduce the ...
