Multilocus Sequence Typing of Vancomycin-Resistant Enterococcus faecium isolate...
Ramos, Sónia; Jones-Dias, Daniela; Caniça, Manuela; Capelo-Martinez, José Luís; Igrejas, Gilberto; Poeta, PatríciaVancomycin-resistant enterococci (VRE) first appeared in the late 1980s in a few European countries. In the last two decades, however, vancomycin-resistant Enterococcus faecium (VREfm) as became an emergent and challenging nosocomial problem. Specific clonal groups of E. faecium show an enhanced capacity to disseminate in the nosocomial setting. These strains can be assigned to distinct clonal groups or complex...
Multilocus Sequence Typing for characterization of potential risk ESBLs-produci...
Ramos, Sónia; Caniça, Manuela; Igrejas, Gilberto; Jones-Dias, Daniela; Capelo-Martinez, José Luís; Poeta, PatríciaInfections caused by Escherichia coli harboring extended-spectrum beta-lactamases (ESBL) have a tremendous impact on public health, because of treatment complications. ESBL-producing E. coli are increasingly reported in healthy food-producing animals that can spread to humans either by direct contact or, more importantly, through the food chain. Here we describe a molecular survey aimed at determining the popul...

Amaral, J.S.; Ribeiro, António E.; Alves, Sofia; Gonçalves, Alexandre; Poeta, PatríciaHerbs and spices have been used for centuries in culinary for seasoning and flavouring purposes. More recently, there has been a growing interest regarding the use of some plants and its essential oils (EO) for their activity against foodborne pathogens and foodspoilage bacteria. Due to its potential in extending the self-life of foods and its better acceptability by consumers who demand more “natural” foods, t...
