Editorial: Fermented Foods-Characterization of the Autochthonous Microbiota

Editorial que introduz o Research Topic “Fermented Foods: Characterization of the Autochthonous Microbiota”, reunindo estudos sobre microbiotas autóctones em alimentos fermentados artesanais e o papel das tecnologias ómicas na compreensão da sua diversidade e função. Destaca avanços na análise de comunidades microbianas e o contributo das fermentações tradicionais para a segurança, qualidade e identidade dos al...

Exploring the Impact of Ultrasound-Assisted Extraction on the Phytochemical Com...

The health benefits of Tamus communis fruits have been associated with their high phenolic content, which comprises several flavonoids. However, the extraction methods might significantly impact these valuable compounds' bioactivity. Therefore, the current study assesses how different extraction techniques affect T. communis extracts' antioxidant, anti-aging, antimicrobial, cytotoxic, anti-inflammatory, and phe...

Emergence, Spread of Antimicrobial-Resistant Bacteria and Phylogenetic Relation...

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...

As 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...

Molecular detection of carbapenemases in Acinetobacter baumannii strains of Por...

Purpose: Carbapenem-resistant Acinetobacter baumannii (CRAB) is an important nosocomial pathogen. The capsular type (K-type) is considered a major virulence factor, contributing to the evasion of host defenses. The global spread and dissemination dynamics between K-types, sequence types (ST), antibiotic resistance genes, and virulence factors remain largely unknown in Portugal. Methods: A collection of 96 CRAB ...

Exploring coaggregation mechanisms involved in biofilm formation in drinking wa...

Aim: Coaggregation, a highly specific cell-cell interaction mechanism, plays a pivotal role in multispecies biofilm formation. While it has been mostly studied in oral environments, its occurrence in aquatic systems is also acknowledged. Considering biofilm formation's economic and health-related implications in engineered water systems, it is crucial to understand its mechanisms. Here, we hypothesized that tra...

Occurrence and diversity of Listeria monocytogenes in Portuguese dairy farms

Listeria monocytogenes is a pathogenic microorganism that causes listeriosis, an infection that usually occurs after consumption of contaminated food and is considered particularly dangerous due to its ability to grow and multiply under adverse conditions. In recent years, there has been an increase in the consumption of unprocessed products, such as raw milk and dairy products, by people of all ages, including...
