A One-Year Systematic Study to Assess the Microbiological Profile in Oysters fr...
Rodrigues, Inês C; Santos-Ferreira, Nânci; Silva, Daniela; da Silva, Carla Chiquelho; Inácio, Ângela S.; Nascimento, Maria São JoséAs filter-feeding animals farmed in water bodies exposed to anthropogenic influences, oysters can be both useful bioremediators and high-risk foodstuffs, considering that they are typically consumed raw. Understanding the dynamic of bacterial and viral load in Pacific oyster (Crassostrea gigas) tissues, hemolymph, outer shell surface biofilm, and farming water is therefore of great importance for microbiologica...
Genotypic and Phenotypic Characterization of Pathogenic Escherichia coli, Salmo...
Batista, Rita; Saraiva, Margarida; Lopes, Teresa; Silveira, Leonor; Coelho, Anabela; Furtado, Rosália; Castro, Rita; Correia, Cristina BeloBirds are potential carriers of pathogens affecting humans and agriculture. Aiming to evaluate the occurrence of the top three most important foodborne pathogens in free-living birds in Portugal, we investigated 108 individual fecal samples from free-living birds and one pooled sample of gull feces (n = 50) for the presence of Escherichia coli (pathogenic and non-pathogenic), Salmonella spp. and Campylobacter s...
Molecular evidence of the close relatedness of clinical, gull and wastewater is...
Varela, Ana Rita; Manageiro, Vera; Ferreira, Eugénia; Guimarães, M. Augusta; da Costa, Paulo Martins; Caniça, Manuela; Manaia, Célia M.Escherichia coli with reduced susceptibility to quinolones isolated from different environmental sources (urban wastewater treatment plants, n = 61; hospital effluent, n = 10; urban streams, n = 9; gulls, n = 18; birds of prey, n = 17) and from hospitalised patients (n = 28) were compared based on multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). The habitats with the most diversifi...
