Evaluation of the pharmacokinetics, pharmacodynamics, and safety of enrofloxacin administration to pregnant mares
… and approved for use in the horse. Enrofloxacin is a fluoroquinolone antibiotic that is available in both oral and intravenous formulations and is commonly used in veterinary medicine. This fluoroquinolone acts by inhibiting bacterial DNA synthesis. Previous work suggests that the …

The effect of antibiotic treatment on Haemophilus parasuis colonization, disease and immunity
… pigs. Moreover, the effect of the antimicrobial enrofloxacin in reducing H. parasuis colonization in weaned pigs was assessed. It was demonstrated that enrofloxacin was able to affect H. parasuis colonization by temporarily reducing the bacterial load in the upper respiratory tract. However, …

DNA supercoiling with a twist
… DNA. We have shown that it interacts with enrofloxacin, a fluoroquinolone antibiotic which otherwise targets DNA gyrase and topoisomerase IV. Enrofloxacin inhibits DNA relaxation by Vaccinia topoisomerase I. When presented with relaxed DNA, the enzyme executes the reverse reaction, …

Prevalence and Dissemination of Antimicrobial Resistance among Campylobacter jejuni and Campylobacter coli from Meat-Animals
… Campylobacter, use of the fluoroquinolone enrofloxacin (trade name, Baytril) was banned in July 2005. However, the impact of this ban on fluoroquinolone resistance in thermophilic campylobacters from turkeys has not been rigorously evaluated yet. In this study, we investigated prevalence of …

Removal of antibiotics from contaminated waters using natural zeolite
… 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 Langmuir-Freundlich sorption model. The …

ADSORPTION OF ANTIBIOTICS BY VERMICULITE
… 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 adsorption processes. The separation factor …

Antimicrobial use practices and resistance in indicator bacteria in communal cattle in the Mnisi community Mpumalanga South Africa
… were resistant to amoxycillin (3%, 2/71) and enrofloxacin (55%, 39/71), intermediate to erythromycin (38%), and completely susceptible to chlortetracycline and vancomycin. E.coli isolates exhibited resistance to colistin (16%, 13/79), amoxycillin (8%, 6/79), chlortetracycline (8%, 6/79) and …

Einfluss der 2. Novelle der Verordnung über tierärztliche Hausapotheken auf den Antibiotikaeinsatz und die Resistenzentwicklung bei Hunden und Katzen in Deutschland
… Amoxicillin-Clavulansäure, Cefovecin und Enrofloxacin wurden bei Staphylococcus (S.) pseudintermedius, S. aureus und Escherichia (E.) coli festgestellt . Im Gegensatz dazu waren Pasteurella (P.) multocida und beta-hämolytische Streptococcus spp. nur wenig resistent. Tierärzte in …

Fate and Dissemination of Salmonella Reading in Market-age Turkeys at Processing using Oral Gavage Challenge Model
… facilities. Upon arrival, a combination of enrofloxacin, 10 mg/kg, and florfenicol, 20 mg/kg, were orally administered sequentially before comingled placement on fresh pine shavings. Turkeys were challenged with 108 cfu SR by oral gavage on days 4 and 7 post-placement. Subsets were subjected …

Genomic diversity and antimicrobial resistance in Salmonella isolates recovered from diverse sources in Nigeria
… identified 32% of the strains to be resistant to enrofloxacin and marbofloxacin and 34% to gentamicin. Multidrug resistance to other antimicrobials was found in some serovars, and poultry isolates had higher resistance than other species, probably due to greater use of antimicrobials in these …

An exploratory study of Helicobacter suis control strategies
… agents (ampicillin, ceftiofur, clarithromycin, enrofloxacin, gentamicin, lincomycin, metronidazole, tetracycline, and tylosine) against nine H. suis isolates. After 48h microaerobic incubation, minimal inhibitory concentrations (MICs) were determined by software-assisted calculation of bacterial …
