Objectives: FOX-type enzymes are a lineage of AmpC-type β-lactamases from Aeromonas spp. whose genes have been mobilized to plasmids spreading among Enterobacteriaceae, where they can be responsible for resistance to extended-spectrum cephalosporins and β-lactamase inhibitor combinations. Little is known about the genetic context and plasmid...

Klebsiella pneumoniae strains producing KPC-type carbapenemases (KPC-KP) are challenging multidrug-resistant pathogens due to their extensively drug-resistant phenotypes and potential for epidemic dissemination in health care settings. Colistin is a key component of the combination antimicrobial regimens used for treatment of severe KPC-KP...

Klebsiella quasipneumoniae is a recently described species, formerly identified as K. pneumoniae phylogroup KpII. Information on pathogenic and virulence potential of this species are lacking. We sequenced the genome of a hypermucoviscous K. quasipneumoniae clinical isolate showing a virulence genes content (allABCDRS, kfuABC, and mrkABCDFHIJ)...

Sequencing of the blaKPC-positive strain Proteus mirabilis AOUC-001 was performed using both the MiSeq and PacBio RS II platforms and yielded a single molecule of 4,272,433 bp, representing the complete chromosome. Genome analysis showed the presence of several acquired resistance determinants, including two copies of blaKPC-2 carried on a...
