Although the majority of human non\u2010typhoidal <jats:italic>Salmonella enterica<\/jats:italic> (<jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content>) cases are the result of foodborne infections or person\u2010to\u2010person transmission, <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> infections may also be acquired by environmental and occupational exposure to animals. While a considerable number of studies have investigated the presence of <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> in farm animals and meat\/carcasses, very few studies have investigated the risk of <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> colonization in humans as a result of direct animal exposure. We investigated asymptomatic <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> colonization in 204 backyard chicken farms, 204 farmers and 306 matched individuals not exposed to chicken farming, in southern Vietnam. Pooled chicken faeces, collected using boot or handheld swabs on backyard chicken farms, and rectal swabs from human participants were tested. <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> colonization <jats:italic>prevalence was<\/jats:italic> 45.6%, 4.4% and 2.6% for chicken farms, farmers and unexposed individuals, respectively. Our study observed a higher prevalence of <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> colonization among chicken farmers (4.4%) compared with age\u2010, sex\u2010 and location\u2010 matched rural and urban individuals not exposed to chickens (2.9% and 2.0%). A total of 164 chicken <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> strains and 17 human <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> strains were isolated, and 28 serovars were identified. <jats:italic>Salmonella<\/jats:italic> Weltevreden was the predominant serovar in both chickens and humans. <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> isolates showed resistance (20\u201340%) against tetracycline, chloramphenicol, sulfamethoxazole\u2010trimethoprim and ampicillin. Our study reflects the epidemiology of <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> colonization in chickens and humans in the Mekong delta of Vietnam and emphasizes the need of larger, preferably longitudinal studies to study the transmission dynamics of <jats:styled-content style=\"fixed-case\">NTS<\/jats:styled-content> between and within animal and human host populations.<\/jats:p>","DOI":"10.1111\/zph.12270","type":"journal-article","created":{"date-parts":[[2016,5,6]],"date-time":"2016-05-06T16:56:47Z","timestamp":1462553807000},"page":"94-99","source":"Crossref","is-referenced-by-count":21,"title":["Non\u2010Typhoidal <i>Salmonella<\/i> Colonization in Chickens and Humans in the Mekong Delta of Vietnam"],"prefix":"10.1111","volume":"64","author":[{"given":"N.
