How do we respond to the threat of multidrug-resistant bacteria? Comparison of antibiotic appraisals from 2016 to 2020 of the French, English, and German HTA agencies.

Antimicrobial resistance (AMR) has become a worldwide growing concern over the past decades. Thus, encouraging manufacturers to develop new antibiotics is needed. We hypothesised that transparency on the regulatory appraisals of antibiotics would provide an incentive to pharmaceutical development.

The role of systemic corticosteroids when treating infections in adult primary care.

Inflammatory response to aggressive infection is responsible not only for symptoms, especially pain, but also for severity, when the inflammatory cascade is violent, and provokes a deleterious cytokine storm. Due to their anti-inflammatory properties, corticosteroids are widely used in ambulatory medical practice. While their beneficial effects on some symptoms, particularly pain, are undeniable, so are the risks associated with their other properties (immunosuppression, neurostimulation, hypermetabolism), even during short-term administration at low doses.

Defining standard and high dosages for β-lactam agents administered by intermittent, prolonged or continuous infusion: a PK/PD simulation study.

Background: The new definitions of antimicrobial susceptibility categories proposed by EUCAST in 2020 require the definition of standard and high dosages of antibiotic. For injectable β-lactams, standard and high dosages have been proposed for short-infusion regimens only.

Objectives: To evaluate dosages for β-lactams administered by prolonged infusion (PI) and continuous infusion (CI).

Swarming of : Through the lens of biophysics.

Swarming is a collective flagella-dependent movement of bacteria across a surface that is observed across many species of bacteria. Due to the prevalence and diversity of this motility modality, multiple models of swarming have been proposed, but a consensus on a general mechanism for swarming is still lacking. Here, we focus on swarming by due to the abundance of experimental data and multiple models for this species, including interpretations that are rooted in biology and biophysics.

The great divide: rhamnolipids mediate separation between and .

The interactions between bacterial species during infection can have significant impacts on pathogenesis. and are opportunistic bacterial pathogens that can co-infect hosts and cause serious illness. The factors that dictate whether one species outcompetes the other or whether the two species coexist are not fully understood.
