Genetic Competence Drives Genome Diversity in Bacillus subtilis
Brito, Patrícia H; Chevreux, Bastien; Serra, Cláudia R; Schyns, Ghislain; Henriques, Adriano O; Pereira-Leal, José BProkaryote genomes are the result of a dynamic flux of genes, with increases achieved via horizontal gene transfer and reductions occurring through gene loss. The ecological and selective forces that drive this genomic flexibility vary across species. Bacillus subtilis is a naturally competent bacterium that occupies various environments, including plant-associated, soil, and marine niches, and the gut of both ...
Resistência de Clostridium difficile do ribotipo 017 ao imipenemo: contributo d...
Isidro, Joana; Santos, Andrea; Nunes, Alexandra; Borges, Vítor; Silva, Catarina; Vieira, Luís; Mendes, Aristides L; Serrano, MónicaA infeção por Clostridium difficile é a principal causa de diarreia infeciosa associada aos cuidados de saúde. Neste estudo, caracterizámos um conjunto de estirpes clínicas de Clostridium difficile, provenientes de diversos hospitais portugueses, com o objetivo de estudar a resistência aos carbapenemos neste agente patogénico. Um total de 191 estirpes clínicas, isoladas entre 2012 e 2015 de 15 hospitais em Port...
Rethinking the Niche of Upper-Atmosphere Bacteria: Draft Genome Sequences of Ba...
Ramos-Silva, Paula; Brito, Patrícia H; Serrano, Mónica; Henriques, Adriano O; Pereira-Leal, José BHere, we report two genome sequences of endospore-forming bacteria isolated from the rice fields of Comporta, Portugal, identified as Bacillus aryabhattai C765 and Bacillus aerophilus C772. Both species were previously identified in air samples from the upper atmosphere, but our findings suggest their presence in a wider range of environmental niches.
