- Raw chicken meat is a vehicle of Ampicillin-multidrug-resistant Enterococcus faecium: is it a on health problem?Publication . Novais, Carla; Freitas, Ana R.; Rebelo, Andreia; Ferreira, Carolina; Duarte, Bárbara; Ribeiro, Sofia; Mourão, Joana; Scholes, Christopher; Antunes, Patrícia; Peixe, LuísaResistance to ampicillin-AmpR is associated with Enterococcus faecium-Efm from hospitalized-humans (clade-A1) and at lesser extent with community-based isolates (clade-A2: human and animal strains; clade-B: human-commensal strains). Recently, AmpR combined with specific putative virulence factors were proposed as molecular markers of Efm linked to human infections, which can have an impact in Efm risk assessment in different public health contexts (PMID:29519512). Here we evaluated the occurrence of AmpR-Efm with potential public health impact in chicken-meat samples.
