Genetic characterization of non-O157 verocytotoxigenic escherichia coli isolated from raw beef products using multiple-locus variable-number tandem repeat analysis
(Mary Ann Liebert, 2011-09)
Verocytotoxigenic Escherichia coli (VTEC) can produce serious human illness linked to the consumption of contaminated food, mainly of bovine origin. There is growing concern about non-O157 VTEC serotypes, which in some ...
Distribution of saa gene variants in verocytotoxigenic Escherichia coli isolated from cattle and food
(Elsevier Science, 2006-04)
The pathogenesis of verocytotoxigenic Escherichia coli (VTEC) infection in humans is multifactorial, given that verocytotoxins are the principal virulence factor. Most strains causing serious diseases possess the eae gene ...
Interventions to reduce verocytotoxigenic Escherichia coli in ground beef in Argentina: A simulation study
(Elsevier Science, 2010-04)
A stochastic simulation model was used to assess the effects of measures implemented in the agri-food-chain to reduce the contamination of ground beef with verotoxigenic Escherichia coli (VTEC). A published risk assessment ...
Occurrence of subtilase cytotoxin and relation with other virulence factors in verocytotoxigenic Escherichia coli isolated from food and cattle in Argentina
(Sociedade Brasileira de Microbiologia, 2011-04)
We investigated the presence of the gene of subtilase cytotoxin (SubAB), described in certain highly virulent verocytotoxigenic E. coli strains, in isolates from Argentina and its relation with other virulence factors. The ...
Quantitative risk assessment for verocytotoxigenic Escherichia coli in ground beef hamburgers in Argentina
(Elsevier Science, 2009-04)
A quantitative risk assessment was developed for verocytotoxigenic Escherichia coli (E. coli VTEC) following hamburger consumption. The assessment considers initial contamination levels, cross-contamination and decontamination ...
Intraserotype diversity among Argentinian verocytotoxigenic Escherichia coli detected by random amplified polymorphic DNA analysis
(Society for General Microbiology, 2006-05)
Most cases of diarrhoea-associated haemolytic uraemic syndrome (HUS) are caused by verocytotoxin-producing Escherichia coli (VTEC). Argentina has the highest worldwide incidence of HUS, but with a lower incidence of VTEC ...
Genetic diversity of O157:H7 and non-O157 verocytotoxigenic Escherichia coli from Argentina inferred from multiple-locus variable-number tandem repeat analysis (MLVA)
(Elsevier Gmbh, 2010-04)
Although serotype O157:H7 has been implicated in most cases of haemolytic-uraemic syndrome (HUS), there is growing concern about non-O157 serotypes of verocytotoxigenic Escherichia coli (VTEC). Multiple-locus variable-number ...
Molecular characterization of Verocytotoxigenic Escherichia coli O157:H7 isolates from Argentina by Multiple-Loci VNTR Analysis (MLVA)
(Sociedade Brasileira de Microbiologia, 2009-12)
The aim of this work was to adapt described MLVA protocols to the molecular typing and characterization of VTEC O157:H7 isolates from Argentina. Nine VNTR loci were amplified by PCR showing diversity values from 0.49 to ...
