Several serovars have caused these events, showing that different BPSs can be contaminated by distinct <jats:italic>Salmonella<\/jats:italic> serovars. The aim of this study was to characterize the genomic diversity of <jats:italic>Salmonella<\/jats:italic> isolates obtained from BPSs in Central Chile to understand their genomic relatedness. A whole\u2010genome SNP\u2010based phylogenetic analysis of 22 <jats:italic>Salmonella<\/jats:italic> isolates from 12 locations revealed that <jats:italic>S.<\/jats:italic> Typhimurium isolates clustered based on the BPS that they were originally isolated from, and the same was established for <jats:italic>S<\/jats:italic>. Enteritidis isolates. Furthermore, our genomic analysis shows that animals from different species (i.e., a chicken, a duck and a pig) carried genetically related <jats:italic>S.<\/jats:italic> Typhimurium strains within the same BPS. Moreover, some of these genetically related isolates were obtained in different years (2013 and 2014), indicating that farm\u2010specific <jats:italic>Salmonella<\/jats:italic> can persist in BPSs for multiple years and that interspecies transmission is plausible in this environment. Understanding the dynamics of interspecies transmission of <jats:italic>Salmonella<\/jats:italic> serovars within a contaminated BPS is fundamental to the design of mitigation strategies to reduce outbreaks of human <jats:italic>Salmonella<\/jats:italic> associated with backyard production systems.<\/jats:p>","DOI":"10.1111\/zph.12526","type":"journal-article","created":{"date-parts":[[2018,9,28]],"date-time":"2018-09-28T01:39:26Z","timestamp":1538098766000},"page":"1008-1014","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Genomics of <i>Salmonella<\/i> contaminating backyard production systems reveals persistence and transmission of genetically related <i>Salmonella<\/i> on a farm basis"],"prefix":"10.1111","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6280-2215","authenticated-orcid":false,"given":"Magaly","family":"Toro","sequence":"first","affiliation":[{"name":"Instituto de Nutrici\u00f3n y Tecnolog\u00eda de los Alimentos Universidad de Chile Santiago Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D\u00e1cil","family":"Rivera","sequence":"additional","affiliation":[{"name":"Escuela de Medicina Veterinaria, Facultad de Ciencias de la Vida Universidad Andres Bello  Santiago Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Viviana","family":"Toledo","sequence":"additional","affiliation":[{"name":"Escuela de Medicina Veterinaria, Facultad de Ciencias de la Vida Universidad Andres Bello  Santiago Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reinaldo","family":"Campos\u2010Vargas","sequence":"additional","affiliation":[{"name":"Centro de Biotecnolog\u00eda Vegetal, Facultad de Ciencias de la Vida Universidad Andres Bello  Santiago Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc W.","family":"Allard","sequence":"additional","affiliation":[{"name":"U.S. Food and Drug Administration Center for Food Safety and Applied Nutrition College Park, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5609-2237","authenticated-orcid":false,"given":"Christopher","family":"Hamilton\u2010West","sequence":"additional","affiliation":[{"name":"Departamento de Medicina Preventiva, Facultad de Ciencias Veterinarias y Pecuarias Universidad de Chile Santiago Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8231-9397","authenticated-orcid":false,"given":"Andrea I.","family":"Moreno\u2010Switt","sequence":"additional","affiliation":[{"name":"Escuela de Medicina Veterinaria, Facultad de Ciencias de la Vida Universidad Andres Bello  Santiago Chile"},{"name":"Millennium Nucleus on Interdisciplinary Approach to Antimicrobial Resistance Santiago Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,9,27]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0950268817002175"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0055254"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.3201\/eid2106.140999"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2164-9-75"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1089\/cmb.2012.0021"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.3201\/eid2210.150765"},{"key":"e_1_2_8_8_1","unstructured":"Center for Disease Control and Prevention(2016).Eight multistate outbreaks of human Salmonella infections linked to live poultry in backyard flocks (Final Update).
