description The virulence factors of pathogens are expressed once they overcome the physiological mechanisms of immune response by the organism, Escherichia coli (E. coli) is a bacterium that is considered a public health problem worldwide due to the high prevalence of resistance and pathogenicity mechanisms expressed, it is mainly related to intestinal infections and is transmitted in the food chain; the genetic determinants encoding virulence factors are transferred between different species or the same, through the mechanism of horizontal gene transfer. The present review aims to describe virulence factors and genes encoding them in E. coli strains isolated from production animals and food products. The databases Medline, Lilacs, ScienceDirect, Scopus, SciELO, and Dialnet were searched using a combination of validated keywords in English (gene, virulence, virulence factor, infection, horizontal gene transfer, mutation, and production animals). Different virulence mechanisms were identified in different production environments, which vary according to the animal and bacterial species. The genes with the highest circulation were Stx1, Stx2 coding for toxins, Saa for adhesins, ehxA for enterohemolysin, eaeA for intimin, and IpfA for fimbriae. Microbiological surveillance and control in the food and animal production area are of great importance to avoid possible disease outbreaks in susceptible populations, due to the effect of virulence factors.

El objetivo de la presente revisión es describir factores de virulencia y genes que los codifican en cepas de E. coli aisladas de animales de producción y de productos alimenticios. En las bases de datos Medline, Lilacs, ScienceDirect, Scopus, SciELO y Dialnet, se realizó búsqueda utilizando una combinación de palabras claves validadas en inglés (gen, virulence, virulence factor, infection, horizontal gene transfer, mutation and production animals). En diferentes ambientes de producción se identificó la presencia de diferentes mecanismos de virulencia que varían según la especie animal y bacteriana, los genes con mayor circulación con Stx1, Stx2 codificantes de toxinas, Saa de adhesinas, ehxA de enterohemolisina, eaeA de intimina, IpfA de fimbrias. La vigilancia y control microbiológico en el área alimenticia y de producción animal es de gran importancia para evitar posibles brotes de enfermedades en población susceptible, por efecto de los factores de virulencia.application/pdftext/xmlspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_agricultura/article/view/13795/11915https://revistas.uptc.edu.co/index.php/ciencia_agricultura/article/view/13795/12387Copyright (c) 2022 Diana Paola López Velandiahttp://creativecommons.org/licenses/by/4.0http://purl.org/coar/access_right/c_abf2Ciencia y Agricultura; Vol. 19 No. 2 (2022): Mayo-AgostoCiencia y Agricultura; Vol. 19 Núm. 2 (2022): Mayo-Agosto2539-0899Escherichia coliFood ChainGenesPolymerase Chain ReactionVirulenceCadena AlimentariaEscherichia coliGenesReacción En Cadena De La PolimerasaVirulenciaGenes and expression of virulence factors in Escherichia coli isolated from production animals.Genes y expresión de factores de virulencia en Escherichia coli aislada en animales de produccióninfo:eu-repo/semantics/articleImagenhttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1Sáenz Rojas , Sebastián AlejandroTorres Caycedo , Maris InésLópez Velandia, Diana Paola001/10683oai:repositorio.uptc.edu.co:001/106832025-07-18 11:01:10.766metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
