Multiple locus variable number tandem repeats (VNTRs) analysis (MLVA) has become a reliable tool, able to establish genetic relationships for epidemiological surveillance and molecular subtyping of pathogens such as verotoxigenic Escherichia coli (VTEC). This emerging pathogen whose primary reservoir is the cattle causes severe disease in humans, such as(More)
Shiga toxin-producing Escherichia coli (STEC) is a foodborne pathogen responsible for severe disease in humans such as hemolytic uremic syndrome (HUS) and cattle, the principal reservoir. Identification of the clones/lineages is important as several characteristics, among them propensity to cause disease varies with STEC phylogenetic origin. At present, we(More)
Dentistry is interested in identifying and controlling adverse events, understood as involuntary injuries to the patient during dental care. The aim of this study was to analyze the adverse events reported to the Office of the Clinical Director at the School of Dentistry at Pontificia Universidad Javeriana (Colombia) during 2011-2012. It was an(More)
Verotoxin-producing E. coli (VTEC) O157:H7 is the dominant serotype isolated from patients with HUS and, Argentina has the highest rate of HUS in the world. Molecular typing had allowed to identify subpopulations related to the origin and virulence of O157:H7 strains. Our aim was to perform a genetic characterization of 43 O157:H7 strains isolated in(More)
The aim of this study was to investigate the prevalence of diarrheagenic E. coli strains in vegetables from the humid Pampa region, Argentina, and to determine the occurrence of serotypes and virulence genes in the isolates. A total of 373 fresh vegetable samples obtained from 41 different geographical points were examined. E. coli was detected in 38.6% of(More)
