Scientists discover a novel family of toxins used in bacterial competition
Publicado em 18 setembro 2020
Researchers at the University of São Paulo (USP) in Brazil have characterized a novel family of anti-bacterial toxins present in bacteria, including Salmonella enterica. This species uses toxic proteins to kill other bacteria in gut microbiota and facilitate colonization of the infected host’s gut.
The study is published in Cell Reports and featured on the cover of the journal.
The novel family’s founding member is the protein Tlde1 (type VI L,D-transpeptidase effector 1), [...]

Scientists develop an optical fiber made of gel derived from marine algae
Publicado em 28 julho 2020An optical fiber made from agar has been produced at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil. This device is edible, biocompatible and biodegradable. It can be used in vivo for imaging body structure, local delivery of light in phototherapy or optogenetics (eg stimulation of neurons with light to study nerve circuits in a living brain) and localized drug delivery. Another possible application is the detection of microorganisms in specific organs, in which [...]ver notícia
