Journal ArticleDOI
Escherichia coli as Commensal and Pathogenic Bacteria Among Food-Producing Animals: Health Implications of Extended Spectrum β-lactamase (ESBL) Production.
Sónia Ramos,Vanessa Silva,Maria de Lurdes Enes Dapkevicius,Manuela Caniça,María Teresa Tejedor-Junco,Gilberto Igrejas,Patrícia Poeta +6 more
TL;DR: The prevalence of antimicrobial resistance in these commensal bacteria (or others, such as enterococci) can be a good indicator for the selective pressure caused by the use of antimacterial agents, providing an early warning of the emergence of antim antibiotic resistance in pathogens.
Journal ArticleDOI
Enterococci, from Harmless Bacteria to a Pathogen.
TL;DR: The dimension of the emergence of enterococcal resistance to key antimicrobial agents, the dissemination of this resistance, and its significance in terms of public health are discussed with the aim of raising awareness of the need to devise and implement surveillance programs and more effective antibiotic stewardship.
Journal ArticleDOI
Genetic characterisation of antibiotic resistance and virulence factors in vanA-containing enterococci from cattle, sheep and pigs subsequent to the discontinuation of the use of avoparcin.
TL;DR: Although gelatinase and haemolytic activity were not detected, the hyl and cylB virulence genes were found within the VRE strains isolated and were identified as Enterococcus faecium.
Journal ArticleDOI
Clonal diversity of ESBL-producing Escherichia coli in pigs at slaughter level in Portugal.
Sónia Ramos,Nuno Silva,Daniela Dias,Margarida Sousa,José Luis Capelo-Martínez,Francisco P. Brito,Manuela Caniça,Gilberto Igrejas,Patrícia Poeta +8 more
TL;DR: The frequent presence of CTX-M-producing E. coli in pigs at slaughter level, most of them belonging to CC10, commonly recovered from clinical samples, is observed.
Journal ArticleDOI
First report on MRSA CC398 recovered from wild boars in the north of Portugal. Are we facing a problem
Margarida Sousa,Nuno Silva,Vera Manageiro,Sónia Ramos,António Coelho,David Gonçalves,Manuela Caniça,Carmen Torres,Gilberto Igrejas,Patrícia Poeta,Patrícia Poeta,Patrícia Poeta +11 more
TL;DR: It is a matter of concern when MRSA and some specific lineages of S. aureus are taken as commensal habitants of the skin and nose of wild animals and are characterized with resistance to various antimicrobial agents in clinical use.
