Journal ArticleDOI
Spread of Extended-Spectrum β-Lactamase CTX-M-Producing Escherichia coli Clinical Isolates in Community and Nosocomial Environments in Portugal
TL;DR: This study suggests that the horizontal transfer of blaCTX-M genes, mediated by plasmids and/or mobile elements, contributes to the dissemination of CTX- M enzymes to community and hospital environments.
Journal ArticleDOI
Patterns and mechanisms of resistance to β-lactams and β-lactamase inhibitors in uropathogenic Escherichia coli isolated from dogs in Portugal
TL;DR: Isolates producing either AmpC or OXA-1 enzymes or producing high levels of TEM-1 beta-lactamases had susceptibility patterns that were difficult to distinguish without IEF and/or amplification of the corresponding specific genes.
Journal ArticleDOI
Occurrence of extended-spectrum β-lactamases among isolates of Salmonella enterica subsp. enterica from food-producing animals and food products, in Portugal.
Lurdes Clemente,Vera Manageiro,Eugénia Ferreira,Daniela Jones-Dias,Ivone Correia,Patrícia Themudo,Teresa Albuquerque,Manuela Caniça +7 more
TL;DR: The presence of bla(CTX-M) genes in Salmonella enterica subsp enterica isolates recovered from poultry and food products of swine origin, in Portugal is reported for the first time.
Journal ArticleDOI
Architecture of Class 1, 2, and 3 Integrons from Gram Negative Bacteria Recovered among Fruits and Vegetables
Daniela Jones-Dias,Vera Manageiro,Eugénia Ferreira,Paula Barreiro,Luís Vieira,Ines B Moura,Manuela Caniça +6 more
TL;DR: The genomic characterization of integron-harboring isolates revealed a high number of mobile genetic elements and clinically relevant antibiotic resistance genes, of which mcr-1, qnrA1, blaGES−11, mphA, and oqxAB are highlighted.
Journal ArticleDOI
Molecular epidemiology and antimicrobial susceptibility of extended- and broad-spectrum β-lactamase-producing Klebsiella pneumoniae isolated in Portugal.
TL;DR: Evidence is provided that the genotypes of K. pneumoniae isolates is changing towards the emergence of ESBL enzymes, and three new enzymes were detected in this period.
