The paper investigates the prevalence of ampicillin-susceptible Enterococcus faecium and E. lactis isolates with low cephalosporin MICs in Spain and Portugal, finding widespread occurrence and diverse genetic factors.

The paper characterizes the spread and resistance mechanisms of vancomycin-resistant Enterococcus faecium in Spanish hospitals, identifying a dominant lineage and plasmid-mediated resistance gene transmission.

This study isolates and characterizes a novel Gardnerella species from the female urinary microbiome, supported by phylogenetic, genomic, and phenotypic evidence.

This paper evaluates a real-time FT-IR ATR workflow for typing carbapenemase-producing Klebsiella pneumoniae isolates, showing high accuracy and enabling rapid outbreak detection.

This study performs a comprehensive pangenome analysis of 153 Gardnerella genomes to uncover genetic diversity, virulence factors, and antibiotic resistance genes, highlighting the need for precise species-level identification.

The paper identifies bacteriocin distribution patterns in Enterococcus faecium and Enterococcus lactis genomes using a tailored database and reveals associations with antibiotic resistance and mobile genetic elements.

This study characterizes K. pneumoniae in poultry production, revealing its genetic diversity, antibiotic resistance, and biocide tolerance across the farm-to-fork chain.

This study analyzes the phylogenetic structure and evolution of Klebsiella pneumoniae clonal groups 14 and 15 using genomic data, revealing independent evolutionary trajectories and the role of plasmids and accessory genomes in their diversification.

The paper analyzes optrA-carrying Enterococcus faecalis genomes to identify common genetic features and a chromosomal hotspot for optrA acquisition across diverse hosts and regions.

This paper validates Fourier Transform Infrared (FT-IR) spectroscopy as a cost-effective method for K-type characterization of Klebsiella pneumoniae, achieving resolution comparable to whole-genome sequencing.
