| description | Salmonella Typhimurium Monophasic variant (STVM), has become a problem in public health globally due to its sudden rise of dominant clones and fast spread. In Colombia, the National Institute of Health reported the circulation of this variant since 2015, ranked sixth among the 20 Salmonella serovars isolated with the highest frequency. Our aim was to characterize genotypically the STVM Colombian isolates confirming the clone-type spreading nationwide. In this study, we included a whole-genome sequencing dataset of 21 Colombian clinical isolates of STVM that were analyzed by using bioinformatics and comparative genomics tools. Our results suggest high genomic plasticity in STVM strains mediated by the acquisition of mobile and conjugative genetic elements, conferring heavy metal tolerance and antibiotic resistance. Moreover, the absence of genes involved in adhesion, invasion, and colonization processes suggest an adaptation process of the new serovar, independently of clonal lineage, source, or geographical origin. |

Salmonella Typhimurium variante Monofásica (STVM) se ha convertido en un problema de salud pública a nivel global, por la sucesiva aparición de clones dominantes y rápida diseminación. En Colombia, el Instituto Nacional de Salud, reporta la circulación de esta variante para el año 2015, posicionada en sexto lugar entre los 20 serovares aislados con mayor frecuencia de Salmonella spp. El objetivo del presente trabajo fue caracterizar genotípicamente los aislamientos de STVM colombianos confirmando el tipo de clon circulante a nivel nacional. En el presente estudio se incluyeron los genomas completos de 21 aislamientos clínicos colombianos de STVM, que se analizaron mediante herramientas computacionales y de genómica comparativa. Los resultados sugieren una alta plasticidad genómica en cepas de STVM mediada por la adquisición de elementos genéticos móviles y conjugativos que confieren tolerancia a metales pesados y resistencia a antibióticos. También, se observó la ausencia de genes involucrados en procesos de adhesión, invasión y colonización, reflejando procesos de adaptación de la nueva serovariedad independiente del linaje clonal, fuente u origen geográfico.
