Diversity of β-lactamase-encoding genes in Escherichia coli strains isolated fr...
Clemente, Lurdes; Correia, Ivone; Albuquerque, Teresa; Geraldes, Margarida; Matos, Filipa; Themudo, Patrícia; Manageiro, Vera; Jones-Dias, DanielaA rapid development of plasmid-mediated resistance to extended-spectrum cephalosporins has been observed in Enterobacteriaceae worldwide, predominantly due to the dissemination of extended-spectrum beta-lactamases (ESBL) and plasmid-mediated AmpC beta-lactamases (PMAB). The aim of the present study was to evaluate the extension of ESBL- and PMAB-producing E. coli strains isolated from different animal origins ...
Occurrence of extended-spectrum beta-lactamases in Salmonella enterica strains ...
Clemente, Lurdes; Correia, Ivone; Themudo, Patrícia; Albuquerque, Teresa; Manageiro, Vera; Jones-Dias, Daniela; Ferreira, Eugénia; Caniça, ManuelaSalmonella enterica is a zoonotic bacteria transmitted through the food chain and isolates harbouring extended-spectrum beta-lactamases (ESBLs) have emerged worldwide during the last decade, with the CTX-M group being particularly important. The aim of the present study was to determine the antimicrobial susceptibility of S. enterica strains isolated from broilers and food of animal origin and to characterize E...
