      Salmonellosis is one of the most important bacterial zoonotic diseases transmitted through the consumption of contaminated food, with chicken and pig related products being key reservoirs of infection. Although numerous ...
    • Insights into c-di-GMP signaling and the PGA exopolysaccharide biological functions using Salmonella as a model organism 

      Echeverz Sarasúa, Maite Upna (2017)   Tesis doctoral / Doktoretza tesia  OpenAccess
      Salmonella es un patógeno alimentario de gran relevancia clínica capaz de adherirse a superficies y formar comunidades bacterianas embebidas en una matriz que ellas mismas producen denominadas biofilms. Esta matriz ...
    • Lack of the PGA exopolysaccharide in Salmonella as an adaptive trait for survival in the host 

      Echeverz Sarasúa, Maite Upna; García Martínez, Begoña Upna; Sabalza Baztán, Amaia; Valle Turrillas, Jaione Upna; Gabaldón Estevan, Juan Antonio; Solano Goñi, Cristina Upna; Lasa Uzcudun, Íñigo Upna (Public Library of Science, 2017)   Artículo / Artikulua  OpenAccess
      Many bacteria build biofilm matrices using a conserved exopolysaccharide named PGA or PNAG (poly-β-1,6-N-acetyl-D-glucosamine). Interestingly, while E. coli and other members of the family Enterobacteriaceae encode the ...
    • Obtención de un alelo de celulosa sintetasa capaz de producir celulosa en ausencia del activador alostérico c-di-GMP 

      Sabalza Baztán, Amaia (2014)   Trabajo Fin de Máster/Master Amaierako Lana  OpenAccess
      La celulosa es uno de los principales componentes de la matriz extracelular de los biofilms formados por algunas especies bacterianas. Los genes involucrados en su síntesis, en el caso de Salmonella Enteritidis, se ...
    • Salmonella biofilm development depends on the phosphorylation status of RcsB 

      Latasa Osta, Cristina Upna; García Martínez, Begoña Upna; Echeverz Sarasúa, Maite Upna; Toledo Arana, Alejandro Upna; Valle Turrillas, Jaione Upna; Campoy Sánchez, Susana; García del Portillo, Francisco; Solano Goñi, Cristina Upna; Lasa Uzcudun, Íñigo Upna (American Society for Microbiology, 2012)   Artículo / Artikulua  OpenAccess
      The Rcs phosphorelay pathway is a complex signaling pathway involved in the regulation of many cell surface structures in enteric bacteria. In response to environmental stimuli, the sensor histidine kinase (RcsC) ...
    • Simultaneous infections by different Salmonella strains in mesenteric lymph nodes of finishing pigs 

      Garrido, Victoria Upna; Sánchez Alarcón, Samanta Rita; San Román Aberasturi, Beatriz Upna; Zabalza Baranguá, Ana Upna; Díaz Tendero, Yasmín; Frutos, Cristina de; Mainar Jaime, Raúl Carlos; Grilló Dolset, María Jesús (BioMed Central, 2014)   Artículo / Artikulua  OpenAccess
      Background: Salmonellosis is a major worldwide zoonosis, and Salmonella-infected finishing pigs are considered one of the major sources of human infections in developed countries. Baseline studies on salmonellosis ...
