Gomes-Sampaio, L. M.; Cláudia-Ferreira, A.; Prata, J. C.; Azevedo, R. M. S.; Pacheco, P.; Campos, Carla; Novais, C.; Peixe, L.; Dinis-Oliveira, R. J.Staphylococcus aureusis the leading bacterial cause of death globally. Nasal carriage of S. aureusincreases the risk of invasive infections, including by methicillin-resistant S. aureus(MRSA) strains, but studies including Portuguese university students (PUS) are scarce. To analyse the prevalence of methicillin-susceptible S. aureus(MSSA) and MRSA among PUS enrolled in different courses/years (1st-4th) at IUCS-...
Novel insights into healthy humans’ faecal carriage of enterococci: Enterococcu...
Almeida-Santos, A. C.; Duarte, B.; Teixeira, M. J.; Tedim, A. P.; Novais, C.; Peixe, L.; Freitas, A. R.Background: Enterococcus lactis (Elts) [former Enterococcus faecium (Efm) clade-B] has been greatly associated with human colonization, but its epidemiology is unknown since this reclassification [1]. We aimed to assess the contemporary faecal carriage of enterococci species among healthy-humans (HH) in Portugal and get novel insights about Efm/Elts differences. Methods: Fifty-one faecal samples (29-women/22-me...

Unraveling the Role of Metals and Organic Acids in Bacterial Antimicrobial Resi...
Rebelo, A; Agostinho Almeida; Peixe, L.; Antunes, Patrícia; Novais, C.Antimicrobial resistance (AMR) has a significant impact on human, animal, and environmental health, being spread in diverse settings. Antibiotic misuse and overuse in the food chain are widely recognized as primary drivers of antibiotic-resistant bacteria. However, other antimicrobials, such as metals and organic acids, commonly present in agri-food environments (e.g., in feed, biocides, or as long-term polluta...

Evolution of Chlorhexidine Susceptibility and of the EfrEF Operon among Enteroc...
Pereira, AP; Antunes, Patrícia; Willems, R; Corander, J; Coque, TM; Peixe, L.; Freitas, AR; Novais, C.Chlorhexidine (CHX) is widely used to control the spread of pathogens (e.g., human/animal clinical settings, ambulatory care, food industry). Enterococcus faecalis, a major nosocomial pathogen, is broadly distributed in diverse hosts and environments facilitating its exposure to CHX over the years. Nevertheless, CHX activity against E. faecalis is understudied. Our goal was to assess CHX activity and the variab...
Diversity of metal and antibiotic resistance genes in Enterococcus spp. from th...
Rebelo, A; Mourao, J; Freitas, AR; Duarte, B; Silveira, E; Sanchez Valenzuela, A; Agostinho Almeida; Baquero, F; Coque, TM; Peixe, L.; Antunes, PatríciaArsenic (As), mercury (Hg), and copper (Cu) are among the major historical and contemporary metal pollutants linked to global anthropogenic activities. Enterococcus have been considered indicators of fecal pollution and antibiotic resistance for years, but its largely underexplored metallome precludes understanding their role as metal pollution bioindicators as well. Our goal was to determine the occurrence, di...

Antunes, Patrícia; Novais, C.; Novais, A; Grosso, F; Ribeiro, TG; Mourao, J; Perovic, SU; Rebelo, A; Ksiezarek, M; Freitas, AR; Peixe, L.Antimicrobial resistance (AMR) is a global societal challenge requiring the contribution of professionals along with general community citizens for their containment. Portugal is one of the European countries where a lack of knowledge on the correct use of antimicrobials and AMR problematic is preeminent. Moreover, youth demotivation to pursue science careers is emerging. To address these problems an innovative...
