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
Cap, Mariana; Carbonari, Claudia Carolina; D’Astek, Beatriz A.; Zolezzi, Gisela; Deza, Natalia; Palladino, Pablo Martin; Masana, Marcelo Oscar; Chinen, Isabel; Rivas, Marta (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 ... -
Genetic features of human and bovine Escherichia coli O157: H7 strains isolated in Argentina
Masana, Marcelo Oscar; Pianciola, Luis; D’Astek, Beatriz A.; Mazzeo, Melina Leonor; Chinen, Isabel; Rivas, Marta (2016-02-15)Shiga toxin-producing Escherichia coli (STEC) are important food-borne pathogens associated with human diseases. In Argentina, O157:H7 is the dominant serotype in hemolytic uremic syndrome (HUS) cases. Previously, we have ... -
Genotypic Characterization of Non-O157 Shiga Toxin–Producing Escherichia coli in Beef Abattoirs of Argentina
Masana, Marcelo Oscar; D’Astek, Beatriz A.; Palladino, Pablo Martin; Galli, Lucia; Del Castillo, Lourdes; Carbonari, Claudia Carolina; Leotta, Gerardo A.; Vilacoba, E.; Irino, K.; Rivas, Marta (2011-12)The non-O157 Shiga toxin–producing Escherichia coli (STEC) contamination in carcasses and feces of 811 bovines in nine beef abattoirs from Argentina was analyzed during a period of 17 months. The feces of 181 (22.3%) bovines ... -
High pressure treatments combined with sodium lactate to inactivate Escherichia coli O157:H7 and spoilage microbiota in cured beef carpaccio
Masana, Marcelo Oscar; Barrio, Yanina Ximena; Palladino, Pablo Martin; Sancho, Ana Maria; Vaudagna, Sergio Ramon (Elsevier, 2014-10-22)High-pressure treatments (400 and 600 MPa) combined with the addition of sodium lactate (1 and 3%) were tested to reduce Escherichia coli O157:H7 (STEC O157) and spoilage microbiota contamination in a manufactured cured ... -
High pressure treatments combined with sodium lactate to inactivate Escherichia coli O157:H7 and spoilage microbiota in cured beef carpaccio
Masana, Marcelo Oscar; Barrio, Yanina Ximena; Palladino, Pablo Martin; Sancho, Ana Maria; Vaudagna, Sergio Ramon (2015-04)High-pressure treatments (400 and 600 MPa) combined with the addition of sodium lactate (1 and 3%) were tested to reduce Escherichia coli O157:H7 (STEC O157) and spoilage microbiota contamination in a manufactured cured ... -
Risk factors for shiga toxin-producing Escherichia coli-associated human diseases
Rivas, Marta; Chinen, Isabel; Miliwebsky, Elizabeth; Masana, Marcelo Oscar (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 ... -
Subtyping of Escherichia coli O157:H7 Strains Isolated from Human Infections and Healthy Cattle in Argentina
Del Castillo, Lourdes; D’Astek, Beatriz A.; Miliwebsky, Elizabeth; Carbonari, Claudia Carolina; Palladino, Pablo Martin; Deza, Natalia; Chinen, Isabel; Manfredi, Eduardo; Leotta, Gerardo A.; Masana, Marcelo Oscar; Rivas, Marta (Mary Ann Liebert, Inc., 2012-05-02)Shiga toxin–producing Escherichia coli (STEC) cause nonbloody (NBD) and bloody diarrhea (BD), and hemolytic uremic syndrome (HUS). Cattle have been described as their main reservoir. STEC O157:H7 is recognized as the ... -
Whole-Genome Sequencing Applied to the Molecular Epidemiology of Shiga Toxin-Producing Escherichia coli O157:H7 in Argentina
Masana, Marcelo Oscar; Carbonari, Claudia Carolina; Fittipaldi, Nahuel; Teatero, Sarah; Athey, Taryn B.T.; Pianciola, Luis; Melano, Roberto G.; Rivas, Marta; Chinen, Isabel (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 ...
