From gut to mud: dissemination of antimicrobial resistance between animal and agricultural niches

Environmental Microbiology, Volume 24, Issue 8, Page 3290-3306, August 2022., 2022
Summary With increasing reports on antimicrobial resistance (AMR) in humans, animals and the environment, we are at risk of returning to a pre‐antibiotic era. Therefore, AMR is recognized as one of the major global health threats of this century. Antibiotics are used extensively in farming systems to treat and prevent infections in food animals or to ...

The pharmacokinetic/pharmacodynamic paradigm for antimicrobial drugs in veterinary medicine: Recent advances and critical appraisal

Journal of Veterinary Pharmacology and Therapeutics, Volume 44, Issue 2, Page 172-200, March 2021., 2021
Abstract Pharmacokinetic/pharmacodynamic (PK/PD) modelling is the initial step in the semi‐mechanistic approach for optimizing dosage regimens for systemically acting antimicrobial drugs (AMDs). Numerical values of PK/PD indices are used to predict dose and dosing interval on a rational basis followed by confirmation in clinical trials. The value of PK/

Structural insights into the mechanism of overcoming Erm-mediated resistance by macrolides acting together with hygromycin-A

Nature Communications, 2023
The ever-growing rise of antibiotic resistance among bacterial pathogens is one of the top healthcare threats today. Although combination antibiotic therapies represent a potential approach to more efficiently combat infections caused by susceptible and ...

Look and Outlook on Enzyme-Mediated Macrolide Resistance

Frontiers in Microbiology, 2018
Since their discovery in the early 1950s, macrolide antibiotics have been used in both agriculture and medicine. Specifically, macrolides such as erythromycin and azithromycin have found use as substitutes for β-lactam antibiotics in patients with ...

Reducing Antimicrobial Use by Implementing Evidence-Based, Management-Related Prevention Strategies in Dairy Cows in Switzerland

Frontiers in Veterinary Science, 2021
The aim of this study was to reduce antimicrobial use (AMU) on dairy farms that implemented evidence-based management strategies. The study not only examined whether these strategies led to a reduction in AMU in practice, but also examined the influence ...

Pathomechanisms and Clinical Implications of Myasthenic Syndromes Exacerbated and Induced by Medical Treatments

Frontiers in Molecular Neuroscience, 2020
Myasthenic syndromes are typically characterized by muscle weakness and increased fatigability due to an impaired transmission at the neuromuscular junction (NMJ).

Impact of ribosomal modification on the binding of the antibiotic telithromycin using a combined grand canonical monte carlo/molecular dynamics simulation approach. [PDF]

PLoS Computational Biology, 2013
Resistance to macrolide antibiotics is conferred by mutation of A2058 to G or methylation by Erm methyltransferases of the exocyclic N6 of A2058 (E. coli numbering) that forms the macrolide binding site in the 50S subunit of the ribosome.

Genetic analysis of methicillin‐susceptible Staphylococcus aureus clinical isolates: High prevalence of multidrug‐resistant ST239 with strong biofilm‐production ability

Journal of Clinical Laboratory Analysis, Volume 34, Issue 11, November 2020., 2020
Biofilm formation involves first, adhesion to surfaces mediated by the expression of different microbial surface components recognizing adhesive matrix molecules (MSCRAMMs) and second, production of polysaccharide intercellular adhesion (PIA) which mediates cell to cell adhesion. Biofilm protects the bacteria from host defenses and prevents delivery of
