    • Determination of molecular phylogenetics of Vibrio parahaemolyticus strains by multilocus sequence typing 
      González Escalona, Narjol; Martínez Urtaza, Jaime; Romero Ormazábal, Jaime; Espejo Torres, Romilio; Jaykus, Lee-Ann; De Paola, Angelo (AMER SOC MICROBIOLOGY, 2008-04)
      Vibrio parahaemolyticus is an important human pathogen whose transmission is associated with the consumption of contaminated seafood. There is a growing public health concern due to the emergence of a pandemic strain causing ...
    • Diversity of Non-O157 shiga toxin-producing escherichia coli isolated from cattle from central and southern Chile 
      Díaz, Leonela; Gutiérrez, Sebastián; Moreno Switt, Andrea; Herve Lelievre, Luis; Hamilton-West Miranda, Christopher Norman; Padola, Nora Lía; Navarrete Wallace, Paola Alejandra; Reyes Jara, Angélica Sofía; Meng, Jianghong; González Escalona, Narjol; Toro Ibaceta, Magaly Alejandra (MDPI, 2021)
      Simple Summary Cattle are the main reservoir of Shiga toxin-producing E. coli (STEC), foodborne pathogens that cause severe disease and outbreaks. However, not all STEC cause human illnesses or have the same virulence ...
    • Epidemiology of Vibrio parahaemolyticus outbreaks, Southern Chile 
      Harth, Erika; Matsuda, Luis; Hernández, Cristina; Rioseco, Maria L.; Romero Ormazábal, Jaime; González Escalona, Narjol; Martínez Urtaza, Jaime; Espejo Torres, Romilio (2009)
      Disease outbreaks caused by Vibrio parahaemolyticus in Puerto Montt, Chile, began in 2004 and reached a peak in 2005 at 3,600 clinical cases. Until 2006, every analyzed case was caused by the serovar O3:K6 pandemic strain. ...
    • Genomic analysis of the diversity, antimicrobial resistance and virulence potential of clinical campylobacter ... 
      Bravo, Verónica; Katz Zondek, Assaf; Porte, Lorena; Weitzel, Thomas; Varela, Carmen; González Escalona, Narjol; BlondelI, Carlos J. (Public Library Science, 2021)
      Campylobacter jejuni and Campylobacter coli are the leading cause of human gastroenteritis in the industrialized world and an emerging threat in developing countries. The incidence of campylobacteriosis in South America ...
    • Polymorphism and gene conversion of the 16S rRNA genes in the multiple rRNA operons of Vibrio parahaemolyticus 
      González Escalona, Narjol; Romero Ormazábal, Jaime; Espejo Torres, Romilio (ELSEVIER SCIENCE BV, 2005-05-15)
      The genome sequence of a strain of Vibrio parahaemolyticus holds 11 copies of rRNA operons (rrn) with identical 16S rRNA genes (rrs). Conversely, the species type strain contains two rrs classes differing in 10 nucleotide ...
    • Quantitative reverse transcription polymerase chain reaction analysis of Vibrio cholerae cells entering the ... 
      González Escalona, Narjol; Fey, Axel; Hofle, Manfred G.; Espejo Torres, Romilio; Guzmán, Carlos A. (BLACKWELL, 2006-04)
      We performed a comparative analysis of the Vibrio cholerae strain El Tor 3083 entering the viable but non-culturable (VBNC) state and starvation after incubation in artificial seawater (ASW) at 4 and 15 degrees C respectively. ...
    • Vibrio parahaemolyticus diarrhea, Chile, 1998 and 2004 
      González Escalona, Narjol; Cachicas, Viviana; Acevedo, Claudia; Rioseco, María; Vergara, Juan; Cabello, Felipe C.; Romero Ormazábal, Jaime; Espejo Torres, Romilio (CENTER DISEASE CONTROL, 2005-01)
      Analysis of clinical isolates of Vibrio parahaemolyticus from outbreaks in Chile in the cities of Puerto Montt in 2004 and Antofagasta in 1998 indicated that 23 of 24 isolates from Puerto Montt and 19 of 20 from Antofagasta ...
    • Whole-genome phylogenetic analysis reveals a wide diversity of Non-O157 STEC isolated from ground beef and ... 
      Gutiérrez Lillo, Sebastián Aldo; Díaz Ruiz, Leonela Isamar; Reyes Jara, Angélica Sofía; Yang, Xun; Meng, Jianghong; González Escalona, Narjol; Toro Ibaceta, Magaly Alejandra (Frontiers Media, 2021)
      Shiga toxin-producing Escherichia coli (STEC) causes foodborne outbreaks that can lead to complications such as hemolytic uremic syndrome. Their main reservoir is cattle, and ground beef has been frequently associated with ...
