A relic of the past: current genetic patterns of the palaeoendemic tree Nothofagus macrocarpa were shaped by climatic oscillations in central Chile
Mathiasen, Paula; Venegas-Gonzalez, Alejandro [Univ Mayor, Fac Ciencias, Hemera Ctr Observac Tierra, Escuela Ingn Forestal, Chile]; Fresia, Pablo; Premoli, Andrea C. (Oxford University Press, 2020-10)Background and Aims The Mediterranean-type forest of central Chile is considered a 'biodiversity hotspot' and a relic of a wider ancient distribution produced by past climatic oscillations. Nothofagus macrocarpa. commonly ... -
Pangenome analysis reveals genetic isolation in Campylobacter hyointestinalis subspecies adapted to different mammalian hosts
Costa, Daniela; Levesque, Simón; Kumar, Nitin; Fresia, Pablo; Ferres, Ignacio; Lawley, Trevor D.; Iraola, Gregorio [Univ Mayor, Ctr Integrat Biol, Chile] (NATURE PORTFOLIO, 2021-02-09)Campylobacter hyointestinalis is an emerging pathogen currently divided in two subspecies: C. hyointestinalis subsp. lawsonii which is predominantly recovered from pigs, and C. hyointestinalis subsp. hyointestinalis which ... -
Simurg: simulate bacterial pangenomes in R
Iraola, Gregorio [Univ Mayor, Ctr Integrat Biol]; Ferres, Ignacio; Fresia, Pablo (OXFORD UNIV PRESS, 2020)Motivation: The pangenome concept describes genetic variability as the union of genes shared in a set of genomes and constitutes the current paradigm for comparative analysis of bacterial populations. However, there is a ... -
Urban metagenomics uncover antibiotic resistance reservoirs in coastal beach and sewage waters
Iraola, Gregorio [Univ Mayor, Ctr Biol Integrat, Santiago, Chile]; Fresia, Pablo; Antelo, Veronica; Salazar, Cecilia; Gimenez, Matias; D'Alessandro, Bruno; Afshinnekoo, Ebrahim; Mason, Christopher; Gonnet, Gaston H. (BMC, 2019)BackgroundMicrobial communities present in environmental waters constitute a reservoir for antibiotic-resistant pathogens that impact human health. For this reason, a diverse variety of water environments are being analyzed ...
