Emergence, Spread of Antimicrobial-Resistant Bacteria and Phylogenetic Relation...
Santos, Dércia; Pinto, Ana Rita; Barata, Rita; Fernandes, Conceição; Guedes, Hugo; Almeida, Gonçalo; Cabecinha, Edna; Monteiro, Sandra M.Coastal environments have been recognized as key reservoirs for antibiotic-resistant bacteria. The present study evaluated marine gastropods, Phorcus lineatus, as potential bioindicators to assess the spread of antibiotic-resistant bacteria. P. lineatus was sampled in four sites, with different anthropogenic pressures, along the northwest Portuguese coastal area. From these specimens, bacteria were isolated and...
Multidrug-Resistant Escherichia coli Accumulated by Freshwater Bivalves: An Und...
Martins, Joana; Gonçalves, Ana; Fernandes, Conceição; Cabecinha, Edna; Monteiro, Sandra Mariza; Guedes, Hugo; Almeida, Gonçalo; Garcia, JulianaAs bioindicators, freshwater bivalves are crucial for the assessment of the contamination impact on different levels of biological integration. Escherichia coli is used as a bioindicator of water fecal contamination, representing a critical global concern, especially with the rise of multidrugresistant (MDR) strains. Phylogenetic diversity, pathotypic characterization, and antibiotic resistance profiles of E. c...
Unveiling the role of taxonomic sufficiency for enhanced ecosystem monitoring
Carreira-Flores, Diego; Rubal, Marcos; Cabecinha, Edna; Diaz-Agra, Guillermo; Gomes, Pedro T.The use of Artificial substrates (AS) as sampling devices addresses challenges in macrofaunal quantitative sampling. While effectively capturing biodiversity patterns, the time-intensitive identification process at the species level remains a substantial challenge. The Taxonomic Sufficiency approach (TS), where only taxa above species level are identified, arises as a potential solution to be tested across diff...
Escherichia coli Phylogenetic and Antimicrobial Pattern as an Indicator of Anth...
Varandas, Simone; Fernandes, Conceição; Cabecinha, Edna; Gomes, Sónia; Silva, Gabriela Jorge da; Saavedra, Maria JoséFreshwater bivalves are widely used as accumulation indicators and monitoring tools for assessing contaminant effects on different levels of biological integration. This pilot study aimed to explore the phylogenetic diversity of Escherichia coli isolated from freshwater mussels (Margaritifera margaritifera and Potomida littoralis) and characterize their phenotypes and antibiotic resistance profiles. Samples wer...

Colonization in artificial seaweed substrates: two locations, one year
Flores, Diego Carreira; Neto, Regina Coelho; Ferreira, Hugo R. S.; Cabecinha, Edna; Díaz-Agras, Guillermo; Rubal, Marcos; Gomes, Pedro T.Artificial substrates have been implemented to overcome the problems associated with quantitative sampling of marine epifaunal assemblages. These substrates provide artificial habitats that mimic natural habitat features, thereby standardizing the sampling effort and enabling direct comparisons among different sites and studies. This paper explores the potential of the “Artificial Seaweed Monitoring System” (AS...
Corredores ecológicos
Freire, Maria da Conceição; Ramos, Isabel Joaquina; Cabecinha, Edna; Faria, Sílvia; Guiomar, NunoEcologia da Paisagem no Contexto Luso-Brasileiro é um livro didático composto por dois volumes. Dando continuidade ao volume I, este volume II é composto por duas partes. Na parte das aplicações são apresentados 14 capítulos nos quais se mostra como a ecologia da paisagem pode ser aplicada nos mais diversos contextos socioambientais em Portugal e no Brasil. A segunda parte deste volume integra três capítulos so...
Antimicrobial susceptibility profiles of multidrug-resistant aeromonads isolate...
Varandas, Simone; Fernandes, Conceição; Gomes, Sónia; Monteiro, Sandra Mariza; Cabecinha, Edna; Teixeira, Amílcar; Saavedra, Maria JoséExtensive use of water and anthropogenic activities contribute to water body pollution. Agricultural, urban, and animal waste, often characterized by numerous toxic and carcinogenic chemicals, pathogenic bacteria, and antibiotics, as well as antibiotic resistance genes (ARGs), loaded with microflora, can contaminate water and enter the food chain, posing a considerable danger to public health [1,2]. The inappro...

Varandas, Simone; Fernandes, Conceição; Gomes, Sónia; Monteiro, Sandra Mariza; Cabecinha, Edna; Teixeira, Amílcar; Saavedra, Maria JoséThe inappropriate use of antibiotics, one of the causes of the high incidence of antimicrobial-resistant bacteria isolated from aquatic ecosystems, represents a risk for aquatic organisms and the welfare of humans. This study aimed to determine the antimicrobial resistance rates among riverine Aeromonas, taken as representative of autochthonous microbiota, to evaluate the level of antibacterial resistance in th...
