    • Bacterial counts in spleen 

      BARQUERO-CALVO, ELIAS; Chacón-Díaz, Carlos; Chaves-Olarte, Esteban; Moreno, Edgardo (Bio-protocol, 2013-11-05)
      Bacterial loads can be determined as colony forming units (CFU) at any point of the infection by culturing spleen homogenates on agar plates. This is a reliable method for comparing the kinetics of infection in various ...
    • Brucella β 1,2 cyclic glucan is an activator of human and mouse dendritic cells 

      Moreno, Edgardo; Martirosyan, Anna; Pérez-Gutierrez, Camino; Banchereau, Romain; Dutartre, Helene; Lecine, Patrick; Dullaers, Melissa; MELLO, Marielle; salcedo, suzana; Muller, Alexandre; Leserman, Lee; Levy, Yves; Zurawski, Gerard; Zurawski, Sandy; Moriyon, Ignacio; Klechevsky, Eynav; Banchereau, Jacques; Oh, SangKon; Gorvel, Jean-Pierre (PLoS Pathogens, 2012-11-15)
      Bacterial cyclic glucans are glucose polymers that concentrate within the periplasm of alpha-proteobacteria. These molecules are necessary to maintain the homeostasis of the cell envelope by contributing to the osmolarity ...
    • Brucellosis caused by the wood rat pathogen Brucella Neotomae: two case reports 

      Arnuy, Ernesto; Rojas, Norman; Villalobos-Vindas, Juan M.; BARQUERO-CALVO, ELIAS; Chacón-Díaz, Carlos; Chaves-Olarte, Esteban; Guzman-Verri, Caterina; Moreno, Edgardo (Journal of Medical Case Reports, 2017-12-19)
      Background: Brucellosis is a chronic bacterial disease caused by members of the genus Brucella. Among the classical species stands Brucella neotomae, until now, a pathogen limited to wood rats. However, we have identified ...
    • Depletion of complement enhances the clearance of Brucella abortus in mice 

      González-Espinoza, Gabriela; BARQUERO-CALVO, ELIAS; Lizano-González, Esteban; Alfaro-Alarcón, Alejandro; Arias-Gómez, Berny; Chaves-Olarte, Esteban; Moreno, Edgardo; Lomonte, Bruno; Chacón-Díaz, Carlos (American Society for Microbiology, 2018-08-06)
      Brucellosis is a bacterial disease of animals and humans. Brucella abortus barely activates the innate immune system at the onset of infection, and this bacterium is resistant to the microbicidal action of complement. Since ...
    • Persistence of Brucella abortus in the bone marrow of infected mice 

      Gutiérrez-Jiménez, Cristina; HYSENAJ, LISIENA; Alfaro-Alarcón, Alejandro; Mora-Cartín, Ricardo; Gorvel, Jean-Pierre; Arce-Gorvel, Vilma; Moreno, Edgardo; BARQUERO-CALVO, ELIAS (Journal of Immunology Research, 2018-12-03)
      Brucellosis is a zoonotic bacterial infection that may persist for long periods causing relapses in antibiotic-treated patients. The ability of Brucella to develop chronic infections is linked to their capacity to invade ...
    • Sex influence on the susceptibility of Swiss mice to Trypanosoma cruzi [Influencia del sexo en la susceptibilidad de ratones Swiss a Trypanosoma cruzi] 

      Zeledón, Rodrigo; Mena-Marín, Ana Laura; Morales, Juan Alberto; Pereira, Mauricio; Urbina-Villalobos, Andrea (Boletin de Malariologia y Salud Ambiental, 2012-10-07)
      Some authors have reported that female mice are more resistant to Trypanosoma cruzi infections than male mice. In order to test this hypothesis we did a comparative study using four isolates of T. cruzi from Costa Rica in ...
    • The potential use of Rattus norvegicus (Mammalia, Muridae) in experimental infections with metacercariae of Paragonimus mexicanus (Digenea, Troglotematidae) 

      Dolz, Gaby; Hernández-Chea, Roderico; Jiménez Rocha, Ana Eugenia; Rubi, Randall (Universidad Nacional, Costa Rica, 2017-01-15)
      Seven Wistar rats (Rattus norvegicus) were experimentally infected with Paragonimus mexicanus metacercariae, obtained from organs and tissues of freshwater crabs (Brachyura: Pseudothelphusidae) collected from the Caribbean ...
