β-Lactam Antibiotics Enhance the Pathogenicity of Methicillin-Resistant Staphylococcus aureus via SarA-Controlled Lipoprotein-Like Cluster Expression

mBio, 2019
Methicillin-resistant Staphylococcus aureus (MRSA) resists nearly all β-lactam antibiotics that have a bactericidal activity. However, whether the empirically used β-lactams enhance MRSA pathogenicity in vivo remains unclear.

Evaluation of a Product Intended for Microbiological Control in Animal Production, and Its Combination With Halquinol

Animal Research and One Health, EarlyView.
Activo Liquid and Halquinol inhibit Salmonella and Escherichia coli in culture media. Activo Liquid exhibits bactericidal action, whereas HA is bacteriostatic, and their combination results in positive or indifferent interactions. This combination effectively inhibits E. coli throughout digestion simulation, thus reducing the required concentrations of

Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

Animal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

A systematic scoping review of metrics utilized to measure antibiotic consumption in hospital settings

British Journal of Clinical Pharmacology, EarlyView.
Abstract Antimicrobial stewardship (AMS) programs were introduced to promote the judicious use of antimicrobials and to combat antimicrobial resistance. Quantifying antibiotic consumption is an important part of AMS initiatives to achieve these objectives.
