      Lamontagne, Julie; Butler, Heather; Chaves, Esteban; Hunter, Joanna; Schirm, Michael; Paquet, Caroline; Tian, Mei; Kearney, Paul; Hamaidi, Lyes; Chelsky, Danie; Moriyón, Ignacio; Moreno, Edgardo; Paramithiotis, Eustache (American Chemical Society, 2007-08-03)
      Brucella virulence is linked to components of the cell envelope and tightly connected to the function of the BvrR/BvrS sensory-regulatory system. To quantify the impact of BvrR/BvrS on cell envelope proteins, we performed ...

      Lamontagne, Julie; Forest, Anik; Marazzo, Elena; François, Denis; Butler, Heather; Michaud, Jean-François; Boucher, Lyne; Pedro, Ida; Villeneuve, Annie; Sitnikov, Dmitri; Trudel, Sylvie; Nassif, Najib; Boudjelt, Djamila; Tomaki, Fadi; Chaves-Olarte, Esteban; Guzman-Verri, Caterina; Brunet, Sylvain; Côté-Martin, Alexandra; Hunter, Joanna; Moreno, Edgardo; Paramithiotis, Eustache (Universidad Nacional, Costa Rica, 2009-03)
      Macrophages were infected with virulent B. abortus strain 2308 or attenuated strain 19. Intracellular bacteria were recovered at different times after infection and their proteomes compared. The virulent strain initially ...
