    • Characterization of genomic island 3 and genetic variability of Chilean field strains of Brucella abortus 
      Céspedes, Sandra; Salgado, Paulina; Valenzuela, Patricio; Vidal, Roberto; Oñate, Angel A. (2011)
      One of the capabilities developed by bacteria is the ability to gain large fragments of DNA from other bacteria or to lose portions of their own genomes. Among these exchangeable fragments are the genomic islands (GIs). ...
    • Distribution of classical and nonclassical virulence genes in enterotoxigenic Escherichia coli isolates ... 
      Del Canto, Felipe; Valenzuela, Patricio; Cantero, Lidia; Bronstein, Jonathan; Blanco, Jesús E.; Blanco, Jorge; Prado Jiménez, Valeria; Levine, Myron; Nataro, James; Sommerfelt, Halvor; Vidal, Roberto (2011)
      Enterotoxigenic Escherichia coli (ETEC) is an important cause of diarrhea. Three adhesins (Tia, TibA, EtpA), an iron acquisition system (Irp1, Irp2, and FyuA), a GTPase (LeoA), and an autotransporter (EatA) are ETEC ...
    • Genes related to long polar fimbriae of pathogenic Escherichia coli strains as reliable markers to identify ... 
      Torres, Alfredo G.; Blanco, Miguel; Valenzuela, Patricio; Slater, Terry M.; Patel, Shilpa D.; Dahbi, Ghizlane; López, Cecilia; Barriga, Ximena Fernández; Blanco, Jesús E.; Gomes, Tânia A.T.; Vidal Álvarez, Roberto; Blanco, Jorge (2009)
      Lpf (stands for long polar fimbriae) is one of the few adhesive factors of enterohemorrhagic Escherichia coli O157:H7 associated with colonization of the intestine. E. coli O157:H7 strains possess two lpf loci encoding ...
    • Identification of coli surface antigen 23, a novel adhesin of enterotoxigenic Escherichia coli 
      Del Canto, Felipe; Botkin, Douglas J.; Valenzuela, Patricio; Popov, Vsevolod; Ruiz-Perez, Fernando; Nataro, James P.; Levine, Myron M.; Stine, O. Colin; Pop, Mihai; Torres, Alfredo G.; Vidal, Roberto (2012)
      Enterotoxigenic Escherichia coli (ETEC) is an important cause of diarrhea, mainly in developing countries. Although there are 25 different ETEC adhesins described in strains affecting humans, between 15% and 50% of the ...
