Article Abstract
Fosfomycin susceptibility testing with Sensititre, Vitek2, Etest, Mic Strip Test and disk diffusion methodologies was compared versus reference agar dilution method (AD) with 78 clinical isolates of KPC-producing Klebsiella pneumoniae. All methodologies showed a Categorical Agreement and Essential Agreement of ≤69% and ≤72%, respectively, revealing a very low concordance with AD.
Objective: Escherichia coli is isolated in most of uncomplicated community-acquired urinary tract infections (UTI) and fosfomycin is one of the treatments of choice. We analyzed the evolution of fosfomycin resistance in extrahospitalary E. coli urinary isolates and whether age and extended spectrum beta-lactamase (ESBL) production were associated to antibiotic resistance.
Aerococcus urinae is an uncommon uropathogen that mainly affect the elderly with predisposing conditions. Aim of the present study was to investigate the clinical and microbiological characteristics of patients with urinary tract infections (UTIs) by A. urinae and determine the antimicrobial susceptibility patterns of the isolates, over the last 3 years at our institution.

The study aimed to assess the high-pressure processing (HPP) impact on antibiotic resistance gene transfer in from food and food processing environments, both in vitro (in microbiological medium) and in situ (in carrot juice), using the membrane filter method. Survival, recovery, and frequency of antibiotic resistance gene transfer analyses were performed by treating samples with HPP at different pressures (200 MPa and 400 MPa). The results showed that the higher pressure (400 MPa) had a significant effect on increasing the transfer frequency of genes such as , encoding fosfomycin resistance, and , , , responsible for tetracycline resistance, both in vitro and in situ.
This study reports the finding of 3 ST8-t008-SCC IVa (2B) methicillin-resistant (MRSA) strains in fresh cheese purchased within a single market in Costa Rica. In line with the finding of the resistance genes , , (C), and (A) in their genomes, these bacteria showed phenotypic resistance to multiple β-lactams and erythromycin. In addition, they carry genes for acquired resistance to aminoglycosides () and fosfomycin (), and genes for a myriad of virulence factors, including adhesins, hemolysins, and exotoxins.

Objectives: While Escherichia coli phylogroup-A is typically associated with commensal strains, some isolates can harbour virulence and exhibit multidrug-resistant (MDR) phenotypes. We report the draft genome of a rare instance of carbapenem, fosfomycin and colistin resistant E. coli phylogroup-A, isolated as part of routine screening of a human patient in a clinical setting in Ireland.
