Persistence of mcr-1-carrying E. coli in rabbit meat production: Challenges bey...
Ribeiro-Almeida, M; Mourao, J; Rodrigues, IC; de Carvalho, AP; da Costa, PM; Peixe, L; Antunes, PatríciaColistin, a last-resort antibiotic in human medicine, has been banned in European food animal production to mitigate antimicrobial resistance. This study investigates the long-term effects of the colistin ban on the occurrence and genomic features (WGS) of colistin-resistant, mcr-carrying Escherichia coli across intensive rabbit farms (8 farms, similar to 600 animals/farm, fecal and farm environmental samples) ...
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...
Tolerance to arsenic contaminant among multidrug-resistant and copper-tolerant ...
Mourao, J; Rebelo, A; Ribeiro, S; Peixe, L.; Novais, Carla; Antunes, PatríciaEmergence and expansion of frequent multidrug-resistant (MDR) major Salmonella clones/serotypes has been a significant threat in the last years. Metal compounds, such as copper, commonly used in animal-production settings, have been pointed out as possible contributors for the selection of such strains/clones. However, the scarcity of studies limits our understanding of the impact of other metal environmental c...
Atypical Non-H2S-Producing Monophasic Salmonella Typhimurium ST3478 Strains fro...
Mourao, J; Rebelo, A; Ribeiro, S; Peixe, L.; Novais, Carla; Antunes, PatríciaPoultry products are still an important cause of Salmonella infections worldwide, with an increasingly reported expansion of less-frequent serotypes or atypical strains that are frequently multidrug-resistant. Nevertheless, the ability of Salmonella to survive antimicrobials promoted in the context of antibiotic reducing/replacing and farming rethinking (e.g., organic acids and copper in feed/biocides) has been...
Imported poultry meat as a source of extended-spectrum cephalosporin-resistant ...
Campos, J; Mourao, J; Silveira, L; Saraiva, M; Correia, CB; Macas, AP; Luisa Peixe; Antunes, PatríciaExtended-spectrum cephalosporin (ESC)-resistant Salmonella have been described at a low level in the EU, nevertheless the increasing importation of poultry meat could be an important source of epidemic strains carrying ESC resistance genes. This study evaluated ESC resistance and its genetic platform among Salmonella isolates from poultry meat products imported into Portugal as well as clonal relatedness of the...

Coherent state transforms for spaces of connections
Ashtekar, A; Lewandowski, J; Marolf, D; Mourao, J; Thiemann, TThe Segal-Bargmann transform plays an important role in quantum theories of linear fields. Recently, Hall obtained a non-linear analog of this transform for quantum mechanics on Lie groups. Given a compact, connected Lie group G with its normalized Haar measure mu(H), the Hall transform is an isometric isomorphism hem L(2)(G, mu(H)) to H(G(C)) boolean AND L(2)(G(C), v), where G(C) the complexification of G, H(G...
