Removal of antibiotics from contaminated waters using natural zeolite
… antibiotics, namely chlortetracycline (CTC), oxytetracycline (OTC), ofloxacin (OFL), and enrofloxacin (ENR), on natural zeolite was investigated. The impact of pH and natural organic matter (NOM) on the sorption process was examined, and the maximum sorption capacity was calculated using the …

Pharmacokinetic Profiles of Oxytetracycline in Yellow Perch (Perca flavescens) as Determined by Plasma Concentration Following Different Routes of Administration
Oxytetracycline (OTC) is one of two antibiotics currently available and approved by the U.S. Food and Drug Administration for use as a chemotherapeutic agent in food fish and is widely used in the aquaculture industry. Previous pharmacokinetic studies of OTC have been conducted in cold water and …

The Pharmacokinetics of Oxytetracycline in Dogs With Normal and Impaired Renal Function
… total body clearance. The pharmacokinetics of oxytetracycline (OTC) were compared before and after the induction of renal failure in three experiments: single intravenous dose (11 dogs), single intravenous and oral dose (8 dogs), and multiple oral doses (10 dogs). Animals were replicated in …

ADSORPTION OF ANTIBIOTICS BY VERMICULITE
… antibiotics, namely chlorotetracycline (CTC), oxytetracycline (OTC), ofloxacin (OFL), and enrofloxacin (ENR), onto natural vermiculite has been studied using batch (static) and column (dynamic) adsorption techniques. The Langmuir and Freundlich isotherm models were initially used to explain the …

Natural transformation and growth inhibition of azotobacter vinelandii in the presence of adsorbed oxytetracycline
… resistance in the soil microbial community. Oxytetracycline (OTC) is a commonly used antimicrobial in large-scale livestock production systems that can persist in the environment. To better understand how adsorbed antimicrobials could affect antimicrobial resistance, the mechanism of OTC …

Use of High Pressure Liquid Chromatography to Detect and Quantify Oxytetracycline Marks in Walleye Otoliths and Dorsal Spines
<p>Oxytetracycline (OTC) is used to chemically mark calcified structures in walleye Stizostedion vitreum fry and fingerlings. Current visual methods for detection of these marks are subjective, and biologists are unable to quantify the amount of OTC in a sample. The goal of this study was to …

A Hydrodynamic Method for Measuring Aqueous Nanoparticle Surface Interactions
… are also environmentally important. Caffeine, oxytetracycline (OTC), and quinine were selected to use as models because of their environmental importance and chemical properties that can be exploited in the system. All of these chemicals are found in the environment; thus, how they interact …

The effects of fish waste and oxytetracycline on the microbenthos
Fish feed, feces and oxytetracycline (OTC) were added to sediment microcosm tanks in 1990, and the physical and biological changes in the benthic environment were followed over a period of 28 days. The main objective was to study the response of the microfauna (benthic microbial and protozoan …

The role of antibiotics metaphylaxis on developmental dynamics of fecal microbiota and persistence of antimicrobial resistome in piglets
… free acid (CCFA), Ceftiofur hydrochloride (CHC), Oxytetracycline (OTC), and Procaine Penicillin G (PPG) at label dose and route. Individual fecal swabs were collected immediately before antimicrobial administration (control = day 0), and again on days 1, 3, 7, and 14 after dosing. Additionally, a …

Pharmacokinetic Studies and Tissue Residue Analysis of Oxytetracycline in Summer Flounder (Paralichthys dentatus) Maintained at Different Production Salinities and States of Health
… allowing for inland intensive fish culture. Oxytetracycline (OTC) is one of two available FDA-approved antibiotics for use in foodfish in the United States. Oxytetracycline was chosen for these studies because it is excreted primarily unchanged through the urine and the absorption, …
