Introduction. Shiga toxin-producing Escherichia coli (STEC) is a foodborne pathogen associated with clinical cases of diarrhea in humans. Its main virulence factors are the Shiga toxins (Stx1 and Stx2). Cattle are the main reservoir of STEC, and many outbreaks in humans have been related to the consumpti...
Escherichia coli productor de toxina Shiga (STEC) es un microorganismo zoonótico que coloniza el tracto intestinal de los animales y causa en el hombre diarrea de severidad variable y enfermedades graves, entre ellas, el síndrome urémico hemolítico post-entérico por STEC (SUH-STEC). El SUH-STEC inte...
Resumen Escherichia coli shigatoxigénica (STEC) está involucrada en el desarrollo del síndrome urémico hemolítico, entre otras enfermedades que son de gran importancia para la salud pública e inocuidad alimentaria a nivel mundial. La capacidad de STEC de formar biofilms en los alimentos y en difere...

The presence of Shiga toxin-producing Escherichia coli (STEC) and resistance to beta-lactams in healthy sheep represents a potential public health risk. This study aimed to characterize STEC isolates in sheep feces for toxin production and resistance to beta-lactam antibiotics. In the present study, amon...
Abstract Thrombotic microangiopathies are disorders characterized by nonimmune microangiopathic hemolytic anemia, thrombocytopenia, and multi-systemic failure. They are classified as thrombotic thrombocytopenic purpura, atypical hemolytic-uremic syndrome, and typical hemolytic uremic syndrome. The latter...
Introducción. La definición habitual de síndrome urémico hemolítico causado por Escherichia coli productora de toxina Shiga (STEC-SUH) se basa en la presencia de anemia, plaquetopenia y elevación de los niveles séricos de creatinina, acompañadas o no de proteinuria y/o hematuria. La definic...
Resumen Objetivo: Aislar STEC en las heces del ganado bovino en el municipio de Ulloa, Valle del Cauca y detectar factores de virulencia asociados con la patogénesis. Materiales y métodos: Se tomaron 21 muestras provenientes de bovinos, las cuales fueron tomadas directamente del recto del animal me...
The population interest for fish consumption has increased, mainly due to several beneficial nutritional
properties presented by this food. In this context, oriental culinary also brings different eating habits
as consume raw food, such as sashimi. A relevant food contaminant of fecal origin is Escherich...
The present study was aimed at subtyping of Stx1 and Stx2 genes and characterization of antimicrobial resistance in 106 Shiga toxin-producing Escherichia coli (STEC) strains isolated from cattle and sheep feces. PCR was used to determine the subtypes, and the disk-diffusion method was used to evaluate th...
Enteropathogenic Escherichia coli (EPEC) and Shigatoxigenic E. coli (STEC) strains are among the major pathotypes found in poultry and their products, which are capable of causing human enteric infections. Colistin has been claimed the drug of choice against diseases caused by multidrug-resistant Gram-ne...
