Experimental TherapeuticsPharmacokinetics and Time-Kill Study of Inhaled Antipseudomonal Bacteriophage Therapy in MiceInhaled bacteriophage (phage) therapy is a potential alternative to conventional antibiotic therapy to combat multidrug-resistant (MDR) Pseudomonas aeruginosa infections. However, pharmacokinetics (PK) and pharmacodynamics (PD) of phages are fundamentally different from antibiotics and the lack of understanding potentially limits optimal dosing. The aim of this study...
Clinical TherapeuticsBacteriophage-Antibiotic Combinations for Enterococcus faecium with Varying Bacteriophage and Daptomycin SusceptibilitiesConcerns regarding increased prevalence of daptomycin (DAP)-resistant strains necessitate novel therapies for Enterococcus faecium infections. Obligately lytic bacteriophages are viruses that target, infect, and kill bacterial cells. Limited studies have evaluated phage-antibiotic combinations against E....
Editor's Pick Experimental TherapeuticsEvaluation of the Activity of a Combination of Three Bacteriophages Alone or in Association with Antibiotics on Staphylococcus aureus Embedded in Biofilm or Internalized in OsteoblastsStaphylococcus aureus is responsible for difficult-to-treat bone and joint infections (BJIs). This is related to its ability to form biofilm and to be internalized and persist inside osteoblasts. Recently, bacteriophage therapy has emerged as a promising option to improve treatment of such infections, but data on its activity against the specific bacterial lifestyles...
Experimental TherapeuticsEfficacy of Bacteriophages in a Staphylococcus aureus Nondiabetic or Diabetic Foot Infection Murine ModelThis study investigated the in vivo efficacy of three bacteriophages combined compared with linezolid in two mouse models (nondiabetic and diabetic) of Staphylococcus aureus foot infection. In both models, a single injection of bacteriophages in the hindpaw showed significant antibacterial efficacy. Linezolid was as effective as bacteriophages in nondiabetic...
Editor's Pick Challenging Clinical Case in Antimicrobial ResistanceA Dutch Case Report of Successful Treatment of Chronic Relapsing Urinary Tract Infection with Bacteriophages in a Renal Transplant PatientWe report a case of a 58-year-old renal transplant patient who developed a recurrent urinary tract infection with an extended-spectrum β-lactamase (ESBL)-positive Klebsiella pneumoniae strain in the first month posttransplant. Even though it tested susceptible to carbapenems and despite repeated meropenem treatment, his infection recurred. The infection eventually...
Clinical TherapeuticsAntibiotics Stimulate Formation of Vesicles in Staphylococcus aureus in both Phage-Dependent and -Independent Fashions and via Different RoutesBacterial membrane vesicle research has so far focused mainly on Gram-negative bacteria. Only recently have Gram-positive bacteria been demonstrated to produce and release extracellular membrane vesicles (MVs) that contribute to bacterial virulence.
