| Abstract (English): | Escherichia coli is a well-known foodborne pathogen that has been associated with serious human disease. Shiga toxin-producing E. coli (STEC) is a subset of the bacteria that produces the cytotoxin Shiga toxin. Ruminants are the most well-known reservoir of STEC; however, pigs have also been reported to harbor this pathogen, becoming a potential risk for humans. The objective of this review was to analyze the prevalence and characterization of pathogenic E. coli in pigs through a systematic literature review following the PRISMA guidelines in four indexed databases (Scopus, PubMed, EBSCO and Web of Science). In total, 39 studies were obtained for the review. STEC was isolated in 87.17% of the studies with an average prevalence of 28%. The most isolated serogroup was O157 and the most prevalent virulence gene was Stx2. It is necessary to expand research into the presence of pathogenic E. coli in pigs and develop prevention and control strategies in the production and supply chain of their products.

| Abstract (Spanish): | Escherichia coli es un conocido patógeno transmitido por los alimentos que ha sido asociado con enfermedades graves en humanos. E. coli productora de toxina Shiga (STEC) es un subconjunto de la bacteria que produce la citotoxina Toxina Shiga. Los rumiantes son el reservorio más conocido de STEC; sin embargo, se ha reportado que los cerdos también pueden llegar a albergar este patógeno, convirtiéndose en un riesgo potencial para el humano. El objetivo de esta revisión fue analizar la prevalencia y caracterización de E. coli patógena en porcinos a través de una revisión sistemática de literatura siguiendo las directrices PRISMA en cuatro bases indexadas (Scopus, PubMed, EBSCO y Web of Science). Se obtuvieron 39 estudios para la revisión. STEC fue aislado en 87.17% de los estudios con una prevalencia promedio de 28%. El serogrupo más aislado fue O157 y el gen de virulencia con mayor prevalencia fue Stx2. Se requiere ampliar las investigaciones sobre la presencia de E. coli patógena en porcinos y desarrollar estrategias de prevención y control en la cadena de producción y suministro de sus productos.
