Special Issue: Vaccines against Antibiotic-Resistant Bacteria: From Bench to Bedside.

The emergence and global dissemination of bacterial strains from numerous species with resistance to multiple antibiotic classes has increased in recent years, both in the healthcare and the community setting [...

Identification of differences in gene expression implicated in the Adherent-Invasive phenotype during infection of intestinal epithelial cells.

Introduction: Adherent-invasive (AIEC) is strongly associated with the pathogenesis of Crohn's disease (CD). However, no molecular markers currently exist for AIEC identification. This study aimed to identify differentially expressed genes (DEGs) between AIEC and non-AIEC strains that may contribute to AIEC pathogenicity and to evaluate their utility as molecular markers.

Fecal carriage of extended-spectrum beta-lactamase-producing Enterobacterales in healthy Spanish schoolchildren.

Background: Extended-spectrum ß-lactamase-producing Enterobacterales (ESBL-E) are a serious threat among emerging antibiotic resistant bacteria. Particularly, the number of cases of ESBL-E infections reported in children has been increasing in recent years, and approved antibiotic treatments for this age group are limited. However, information regarding the prevalence of colonization in European children, risk factors associated with colonization, and the characteristics of the colonizing strains is scarce.

Role of peptidoglycan recycling enzymes AmpD and AnmK in virulence features.

is an important causative agent of hospital acquired infections. In addition to acquired resistance to many currently-available antibiotics, it is intrinsically resistant to fosfomycin. It has previously been shown that AmpD and AnmK contribute to intrinsic fosfomycin resistance in due to their involvement in the peptidoglycan recycling pathway.
