- Genomic diversity of Enterobacteriaceae on food-processing surfaces: an overlooked non-clinical setting with public health implicationsPublication . Peixoto, Andreia; Nova, Lúcia; Mourão, Joana; Matos, Cátia; Santos, Susana; Rodrigues, João; Saraiva, Margarida; Correia, Cristina Belo; Batista, Rita; Peixe, Luísa; Novais, Carla; Antunes, PatríciaBacterial hazards on contaminated surfaces in food-processing environments pose significant food safety risks. Hygiene monitoring of surfaces in direct or indirect contact with food typically relies on a limited set of bacterial indicators, such as Enterobacteriaceae counts. However, their genomic diversity remains poorly characterised. The aim of this study was to provide a comprehensive genomic characterisation of Enterobacteriaceae recovered from food-contact surfaces after cleaning and disinfection with biocides in foodservice units. Diverse strains were identified, with some STs shared across samples and/or foodservices. - A diverse Enterobacteriaceae population persists on food-contact surfaces even after cleaning and disinfection with biocides, with evidence of cross-contamination. - These surfaces represent critical points of contact for strains that are genetically similar to those circulating in food, environment, and human clinical sources, including strains carrying clinically relevant AMR genes. - Further research is needed to understand the factors driving their persistence and dissemination in foodservice environments, aiming to enhance food safety risk management protocols and protect public health.
- Leishmaniasis retrospective analysis of cases diagnosed in the National Institute of Health between 2020 and 2024Publication . Reis, Tânia; Vilares, Anabela; Ferreira, Idalina; Martins, Susana; Gargaté, Maria JoãoAim: To describe the demographic characteristics of leishmaniasis cases, in patients with clinical symptoms, whose laboratory diagnosis was confirmed between 2020 and 2024 at the National Reference Lab of Parasitic and Fungal Infections.
- REVIVE - Leishmania infantum detected in Sergentomyia minuta in the Algarve region, PortugalPublication . Vilares, Anabela; Amaro, Fátima; Reis, Tânia; Martins, Susana; Alves, Maria João; Gargaté, Maria João; REVIVE TeamLeishmaniasis caused by Leishmania donovani represents a major public health concern in Mediterranean countries, with phlebotomine sand flies serving as the primary vectors for the transmission of Leishmania parasites [1]. In Portugal, REVIVE is a national surveillance network operating under the Ministry of Health since 2008, initially targeting mosquitoes, with its scope expanded to include ticks in 2011 and sand flies in 2016. The primary objectives of REVIVE are to identify the existing species in Portugal, establish which pathogens are circulating among them and provide alerts for prevention and control measures when necessary.
