Helicobacter pylori have coevolved with mankind since its origins, adapting to different human groups. In America, H. has evolved into several subpopulations. We analysed the genome of 154 Colombian strains along 1,091 from worldwide populations discern ancestry and adaption people. Population structure was inferred FineStructure ChromoPainter. Phylogenetic relationship relative effect recombination were analysing core SNPs. Also, a Fst index calculated identify gene variants strongest...

Helicobacter pylori infection has been associated with various gastrointestinal disorders, including chronic gastritis, peptic ulcers, dyspepsia, and gastric cancer. This study aimed to compare the effectiveness of four invasive diagnostic methods for detecting H. in 297 patients premalignant lesions In this cross-sectional study, evaluated included Giemsa stain, vitro culture, rapid urease test, polymerase chain reaction. Patients were recruited between 2016 2019 Ibagué, a case definition...

Abstract Background: A substantial portion of the genetic predisposition for breast cancer is explained by multiple common variants relatively small effect. subset these variants, which have been identified mostly in individuals European and Asian ancestry, combined to construct a polygenic risk score (PRS) predict risk, but prediction accuracy existing PRSs Hispanic/Latinx (H/L) remain low. We assessed performance several PRS panels with without addition H/L specific among self-reported...

Introducción. El cáncer colorrectal es una carga para la salud pública en Colombia y el mundo. Estudios de asociación genética han identificado regiones cromosómicas asociadas a esta enfermedad, mostrando riesgo variable entre poblaciones, debido historia demográfica ancestría genética. Objetivo. Estudiar que aportan 20 marcadores al Colombia, empleando 955 casos 972 controles del consorcio CHIBCHA, analizando conjuntamente efecto global local. Metodología. Las muestras se genotipificaron...

We present the complete genome sequences of three Helicobacter pylori strains isolated from patients who resided in Tolima Department, Colombia, diagnosed with chronic gastritis. The genomes an average length 1.6 Mbp and 1,546 genes correspond to different H. subpopulations.

Abstract Helicobacter pylori have coevolved with mankind since its origins, adapting to different human groups. In America H. has evolved in several subpopulations specific for regions or even countries. this study we analyzed the genome of 163 Colombian strains along 1,113 that represent worldwide populations better discern ancestry and adaption people. Population structure was inferred FineStructure chromosome painting identifying proportion ancestries isolates. Phylogenetic relationship...
