    • Expression of the biofilm-associated protein interferes with host protein receptors of Staphylococcus aureus and alters the infective process 

      Cucarella, Carme; Tormo Más, María Ángeles; Knecht, Erwin; Amorena Zabalza, Beatriz Upna; Lasa Uzcudun, Íñigo Upna; Foster, Timothy J.; Penadés, José R. (American Society for Microbiology, 2002)   Artículo / Artikulua  OpenAccess
      The adherence of Staphylococcus aureus to soluble proteins and extracellular-matrix components of the host is one of the key steps in the pathogenesis of staphylococcal infections. S. aureus presents a family of adhesins ...
    • Moonlighting bacteriophage proteins derepress staphylococcal pathogenicity islands 

      Tormo Más, María Ángeles; Mir, Ignacio; Shrestha, Archana; Tallent, Sandra M.; Campoy Sánchez, Susana; Lasa Uzcudun, Íñigo Upna; Barbé, Jordi; Novick, Richard P.; Christie, Gail E.; Penadés, José R. (Nature Research, 2010)   Artículo / Artikulua  OpenAccess
      Staphylococcal superantigen-carrying pathogenicity islands (SaPIs) are discrete, chromosomally integrated units of ∼15 kilobases that are induced by helper phages to excise and replicate. SaPI DNA is then efficiently ...
    • RinA controls phage-mediated packaging and transfer of virulence genes in gram-positive bacteria 

      Ferrer, María Desamparados; Quiles Puchalt, Nuria; Harwich, Michael D.; Tormo Más, María Ángeles; Campoy Sánchez, Susana; Barbé, Jordi; Lasa Uzcudun, Íñigo Upna; Novick, Richard P.; Christie, Gail E.; Penadés, José R. (Oxford University Press, 2011)   Artículo / Artikulua  OpenAccess
      Phage-mediated transfer of microbial genetic elements plays a crucial role in bacterial life style and evolution. In this study, we identify the RinA family of phage-encoded proteins as activators required for transcription ...
    • Role of biofilm-associated protein bap in the pathogenesis of bovine Staphylococcus aureus 

      Cucarella, Carme; Tormo Más, María Ángeles; Ubeda, Carles; Trotonda, María Pilar; Monzon, Marta; Peris, Cristòfol; Amorena Zabalza, Beatriz Upna; Lasa Uzcudun, Íñigo Upna; Penadés, José R. (American Society for Microbiology, 2004)   Artículo / Artikulua  OpenAccess
      Staphylococcus aureus is a common cause of intramammary infections, which frequently become chronic, associated with the ability of the bacteria to produce biofilm. Here, we report a relationship between the ability to ...
    • Role of staphylococcal phage and SaPI integrase in intra- and interspecies SaPI transfer 

      Maiques, Elisa; Ubeda, Carles; Tormo Más, María Ángeles; Ferrer, María Desamparados; Lasa Uzcudun, Íñigo Upna; Novick, Richard P.; Penadés, José R. (American Society for Microbiology, 2007)   Artículo / Artikulua  OpenAccess
      SaPIbov2 is a member of the SaPI family of staphylococcal pathogenicity islands and is very closely related to SaPIbov1. Typically, certain temperate phages can induce excision and replication of one or more of these islands ...
    • SarA is an essential positive regulator of Staphylococcus epidermidis biofilm development 

      Tormo Más, María Ángeles; Martí, Miguel; Valle Turrillas, Jaione Upna; Manna, Adhar C.; Cheung, Ambrose L.; Lasa Uzcudun, Íñigo Upna; Penadés, José R. (American Society for Microbiology, 2005)   Artículo / Artikulua  OpenAccess
      Staphylococcus epidermidis biofilm formation is associated with the production of the polysaccharide intercellular adhesin (PIA)--poly-N-acetylglucosamine polysaccharide (PNAG) by the products of the icaADBC operon. ...
    • Staphylococcus aureus pathogenicity island DNA is packaged in particles composed of phage proteins 

      Tormo Más, María Ángeles; Ferrer, María Desamparados; Maiques, Elisa; Ubeda, Carles; Selva, Laura; Lasa Uzcudun, Íñigo Upna; Calvete, Juan J.; Novick, Richard P.; Penadés, José R. (American Society for Microbiology, 2008)   Artículo / Artikulua  OpenAccess
      Staphylococcus aureus pathogenicity islands (SaPIs) have an intimate relationship with temperate staphylococcal phages. During phage growth, SaPIs are induced to replicate and are efficiently encapsidated into special small ...
    • A super-family of transcriptional activators regulates bacteriophage packaging and lysis in Gram-positive bacteria 

      Quiles Puchalt, Nuria; Tormo Más, María Ángeles; Campoy Sánchez, Susana; Toledo Arana, Alejandro Upna; Monedero, Vicente; Lasa Uzcudun, Íñigo Upna; Novick, Richard P.; Christie, Gail E.; Penadés, José R. (Oxford University Press, 2013)   Artículo / Artikulua  OpenAccess
      The propagation of bacteriophages and other mobile genetic elements requires exploitation of the phage mechanisms involved in virion assembly and DNA packaging. Here, we identified and characterized four different families ...
