Background: The anti-biofilm efficacy of dalbavancin (DAL) has been evaluated in static models. The comparative activity of DAL alone and with rifampicin (RIF) against biofilm-embedded methicillin-resistant Staphylococcus aureus (MRSA) was evaluated using an in vitro pharmacokinetic/pharmacodynamic (PK/PD) model.
Methods: Two MRSA strains (HUB-4, HUB-5) were evaluated with the Calgary Device System and the dynamic CDC-Biofilm Reactor over 144 h.
Aims: To evaluate if microbial load from diabetic foot ulcers (DFUs) can help in predicting outcomes.
Methods: A multicenter prospective cohort study was performed in an outpatient setting (September 1, 2017-January 31, 2019) in diabetic patients with DFU.Quantitative cultures from DFU tissue biopsies at a baseline visit were obtained; high and low microbial loads were defined as ≥6logCFU/mL and <6logCFU/mL, respectively.
Objectives: To characterize the mechanisms of antimicrobial resistance and the prevalence of the polysaccharide capsule among urogenital and respiratory Haemophilus parainfluenzae isolates.
Methods: Antimicrobial susceptibility was tested by microdilution. Fifty-five MDR strains were subjected to WGS and were phylogenetically compared with all the available H.
Haemophilus parainfluenzae (HPAR) is a Gram-negative bacterium that can become an opportunistic urogenital pathogen. Recently, multidrug resistant (MDR) strains have emerged. We aim to analyse the epidemiology of HPAR at Hospital Universitari de Bellvitge between 2013 and 2017 to determine its putative role in sexually transmitted infections (STI).

The objectives of this work were to characterise a new capsular operon of extensively drug-resistant (XDR) H. parainfluenzae clinical isolates and study their resistance mechanisms using whole-genome sequencing.

Methods: Using an in vitro pharmacodynamic biofilm model, this study evaluated the comparative efficacy of ceftolozane/tazobactam against MDR/extensively drug-resistant (XDR) P.
