Multistrain models predict sequential multidrug treatment strategies to result in less antimicrobial resistance than combination treatment [PDF]

, 2016
Background Combination treatment is increasingly used to fight infections caused by bacteria resistant to two or more antimicrobials. While multiple studies have evaluated treatment strategies to minimize the emergence of resistant strains for single ...

Live to cheat another day: bacterial dormancy facilitates the social exploitation of beta-lactamases [PDF]

, 2015
The breakdown of antibiotics by β-lactamases may be cooperative, since resistant cells can detoxify their environment and facilitate the growth of susceptible neighbours. However, previous studies of this phenomenon have used artificial bacterial vectors

Antibiotic residues and antibiotic-resistant bacteria in pig slurry used to fertilize agricultural fields [PDF]

, 2020
Pig manure may contain antibiotic residues, antibiotic-resistant bacteria or pathogens, which may reach the environment upon fertilization. During this study, 69 antibiotic residues belonging to 12 classes were quantified in 89 pig slurry samples.

Antimicrobial Biophotonic Treatment of Ampicillin-Resistant Pseudomonas aeruginosa with Hypericin and Ampicillin Cotreatment Followed by Orange Light

Pharmaceutics, 2019
Bacterial antibiotic resistance is an alarming global issue that requires alternative antimicrobial methods to which there is no resistance. Antimicrobial photodynamic therapy (APDT) is a well-known method to combat this problem for many pathogens ...
