Bacterial load and dynamics: exploring their potential as biomarkers for postmo...
Teixeira, Maria J.; Barbosa, Daniel J.; Dinis-Oliveira, Ricardo Jorge; Freitas, Ana R.Background: Establishing the postmortem interval (PMI), the time since death, is vital in forensic investigations but remains challenging due to multiple factors like the cause of death, body location, and environmental conditions [1]. Traditional PMI estimation methods include Algor Mortis, Rigor Mortis, and Livor Mortis, along with complementary approaches from entomology, botany, and microbiology, though all...
Identification of linezolid-resistant Enterococcus spp. in calves: findings fro...
Ribeiro, Alícia; Teixeira, Maria J.; Pinho, Luís; Campos, Carla; Novais, Carla; Peixe, Luísa; Brito, Nuno V.; Quinteira, Sandra; Miranda, CarlaBackground: Antimicrobial resistance (AMR) is a global health threat requiring a One Health approach, as antibiotic-resistant bacteria can spread between animals and humans. Enterococcus spp., particularly E. faecium (Efm) and E. faecalis (Efs), are key AMR indicators due to their role as gut commensals and their potential as reservoirs of resistance genes. They are also opportunistic pathogens that can cause s...
Essential oils from croton species: chemical composition, in vitro and in silic...
Morais, Selene M.; Cossolosso, Danyelle S.; Silva, Antonio A. S.; Moraes Filho, Manoel O. de; Teixeira, Maria J.; Campello, Claudio CabralChemotherapy treatment of leishmaniasis is based on the use of pentavalent antimonials, but these drugs present low efficacy and high toxicity. In the search for new antileishmanial agents, essential oils (EOs) from four Croton species (C. argyrophylloides, C. jacobinensis, C. nepetifolius and C. sincorensis) were evaluated against Leishmania infantum chagasi, L. amazonensis and L. braziliensis. EOs were analyz...
Avaliação microbiológica de embalagens e materiais de embalagem para uso alimentar
Santos, Isabel; Teixeira, Maria J.; Carneiro, Luísa; Poças, Fátima; Mena, CristinaO papel da embalagem alimentar pode ser abordado segundo duas perspetivas diferentes. Por um lado, a embalagem desempenha um papel muito importante na proteção e na conservação dos alimentos, contribuindo assim para a sua qualidade e segurança. Por outro lado, a embalagem não deve contribuir com perigos físicos, químicos ou microbiológicos, que condicionem a qualidade e segurança dos alimentos. De acordo com o ...
