    • Capsicumicine, a new bioinspired peptide from red peppers prevents staphylococcal biofilm in vitro and in vivo via a matrix anti-assembly mechanism of action 

      Von Borowski, Rafael Gomes; Chat, Sophie; Schneider, Rafael de Oliveira; Nonin-Lecomte, Sylvie; Bouaziz, Serge; Giudice, Emmanuel; Zimmer, Aline Rigon; Gnoatto, Simone Cristina Baggio; Macedo, Alexandre José; Gillet, Reynald (2021) [Journal article]
      Staphylococci are pathogenic biofilm-forming bacteria and a source of multidrug resistance and/or tolerance causing a broad spectrum of infections. These bacteria are enclosed in a matrix that allows them to colonize medical ...

    • Effects of zinc transporters on Cryptococcus gattii virulence 

      Schneider, Rafael de Oliveira; Padilha, Camila Diehl; Santos, Francine Melise dos; Piffer, Alicia Corbellini; Garcia, Ane Wichine Acosta; Kulmann, Marcos Iuri Roos; Schrank, Augusto; Silva, Lívia Kmetzsch Rosa e; Vainstein, Marilene Henning; Staats, Charley Christian (2015) [Journal article]
      Zinc is an essential nutrient for all living organisms because it is a co-factor of several important proteins. Furthermore, zinc may play an essential role in the infectiousness of microorganisms. Previously, we determined ...

    • Homeostase de zinco na virulência de cryptococcus gattii e na interação com hospedeiro 

      Schneider, Rafael de Oliveira (2016) [Thesis]
      A imunidade nutricional é um importante mecanismo de defesa do hospedeiro. A mesma é caracterizada pela privação de nutrientes durante interação patógeno e hospedeiro, mostrando-se essencial tanto para eliminar quanto para ...

    • Metabolismo de zinco em Cryptococcus gattii : caracterização de mecanismos regulatórios de transporte 

      Schneider, Rafael de Oliveira (2012) [Dissertation]
      Cryptococcus gattii é uma levedura basidiomicética causadora da criptococose, doença que acomete diferentes órgãos de pacientes imunocompetentes, entre eles, pulmões, pele e sistema nervoso central. Durante o processo ...

    • Pathogenic diversity amongst serotype C VGIII and VGIV Cryptococcus gattii isolates 

      Rodrigues, Jéssica; Fonseca, Fernanda L.; Schneider, Rafael de Oliveira; Godinho, Rodrigo M. da C.; Firacative, Carolina; Maszewska, Krystyna; Meyer, Wieland; Schrank, Augusto; Staats, Charley Christian; Silva, Lívia Kmetzsch Rosa e; Vainstein, Marilene Henning; Rodrigues, Márcio L.
