Aplicación de la técnica PMA-qPCR para detectar viabilidad de Escherichia coli productor de toxina Shiga (STEC) en hamburguesas de carne vacuna.
(2019-11)El PMA (propidium monoazide) es un colorante fotoreactivo que se intercala en el ADN bacteriano de las células muertas e inhibe su amplificación. Su selectividad se fundamenta en que la membrana bacteriana es impermeable ... -
Combination of organic acids and low-dose gamma irradiation as antimicrobial treatment to inactivate Shiga toxin-producing Escherichia coli inoculated in beef trimmings: Lack of benefits in relation to single treatments
(Plos ONE, 2020-03-26)The aim of this study was to assess the efficacy of lactic acid (LA), caprylic acid (CA), high- (HDI) and low- (LDI) dose gamma irradiation and LDI combined with LA or CA on the inactivation of a pool of Shiga toxin-producing ... -
Estrategias de intervención para mitigar el impacto de Escherichia coli productor de toxina Shiga en la cadena cárnica bovina.
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2021)Shiga toxin-producing Escherichia coli (STEC) are foodborne pathogens that can cause bloody diarrhea, hemorrhagic colitis and hemolytic uremic syndrome. The meat contaminated with STEC impacts on the public health due to ... -
Frequency, characterization and genotypic analysis of Shiga toxin-producing Escherichia coli in beef slaughterhouses of Argentina = Frecuencia, caracterización y análisis genotípico de Escherichia coli productor de toxina Shiga en frigoríficos de carne bovina de Argentina
(2018-06-22)The objectives of this study were: (1) to estimate STEC frequency in hide and carcass samples taken from beef slaughterhouses supplying the domestic market in Argentina, (2) to establish the pheno-genotypic characteristics ... -
Inactivation of Shiga toxin-producing Escherichia coli in fresh beef by electrolytically-generated hypochlorous acid, peroxyacetic acid, lactic acid and caprylic acid
(Elsevier, 2019-07-05)Several studies have been conducted to verify the decontamination potential of electrolyticallygenerated hypochlorous acid, peroxyacetic acid, lactic acid and caprylic acid against Shiga toxin-producing Escherichia coli ... -
Risk factors for shiga toxin-producing Escherichia coli-associated human diseases
(American Society for Microbiology, 2014)We have reviewed the risk factors for the occurrence of Shiga toxin-producing Escherichia coli (STEC)-associated human diseases. The analysis of STEC surveillance data and trends shows differences in frequency and severity ... -
Validación de irradiación para reducir la presencia de Escherichia coli productor de toxina Shiga en carne picada fresca.
(2019-09)Escherichia coli productor de toxina Shiga (STEC) es el agente causal de diarreas con o sin sangre y, en los casos más severos, del Síndrome Urémico Hemolítico. La carne picada ha sido descripta como uno de los principales ... -
Whole-Genome Sequencing Applied to the Molecular Epidemiology of Shiga Toxin-Producing Escherichia coli O157:H7 in Argentina
(American Society for Microbiology, 2016-10-07)Shiga toxin-producing Escherichia coli strains are worldwide associated with sporadic human infections and outbreaks. In this work, we report the availability of high-quality draft whole-genome sequences for 19 O157:H7 ...
