Rats are ubiquitous in areas of human activity and farms in the Mekong Delta; in addition, trapping and trading of rats for food is common. To correctly assess the human risks due to rat trapping, marketing, and carcass dressing, further studies are needed to establish the routes of transmission and cycle of infection. The widespread presence of these zoonotic pathogens in rats and the abundance of human\u2014rat interactions suggest that surveillance efforts should be enhanced to detect any human cases of\n                    <jats:italic toggle=\"yes\">Bartonella<\/jats:italic>\n                    infection that may arise.\n                  <\/jats:p>","DOI":"10.1089\/vbz.2014.1604","type":"journal-article","created":{"date-parts":[[2015,1,28]],"date-time":"2015-01-28T08:58:16Z","timestamp":1422435496000},"page":"40-47","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":38,"title":["<i>Bartonella<\/i>\n                    Species and Trombiculid Mites of Rats from the Mekong Delta of Vietnam"],"prefix":"10.1177","volume":"15","author":[{"given":"Hoang Kim","family":"Loan","sequence":"first","affiliation":[{"name":"Institute Pasteur","place":["Vietnam"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nguyen Van","family":"Cuong","sequence":"additional","affiliation":[{"name":"Oxford University Clinical Research Unit","place":["Vietnam"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ratree","family":"Takhampunya","sequence":"additional","affiliation":[{"name":"AFRIMS","place":["Thailand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kewalin","family":"Klangthong","sequence":"additional","affiliation":[{"name":"AFRIMS","place":["Thailand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lynn","family":"Osikowicz","sequence":"additional","affiliation":[{"name":"Centre for Disease Control"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bach Tuan","family":"Kiet","sequence":"additional","affiliation":[{"name":"Sub-Department of Animal Health","place":["Vietnam"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Campbell","sequence":"additional","affiliation":[{"name":"Oxford University Clinical Research Unit","place":["Vietnam"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliet","family":"Bryant","sequence":"additional","affiliation":[{"name":"Oxford University Clinical Research Unit","place":["Vietnam"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sommai","family":"Promstaporn","sequence":"additional","affiliation":[{"name":"AFRIMS","place":["Thailand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Kosoy","sequence":"additional","affiliation":[{"name":"Centre for Disease Control"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nguyen Van","family":"Hoang","sequence":"additional","affiliation":[{"name":"Sub-Department of Animal Health","place":["Vietnam"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serge","family":"Morand","sequence":"additional","affiliation":[{"name":"Institute Nationale de la Recherche Agricole","place":["France"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yannick","family":"Chaval","sequence":"additional","affiliation":[{"name":"Institute Nationale de la Recherche Agricole","place":["France"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vo Be","family":"Hien","sequence":"additional","affiliation":[{"name":"Sub-Department of Animal Health","place":["Vietnam"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Carrique-Mas","sequence":"additional","affiliation":[{"name":"Oxford University Clinical Research Unit","place":["Vietnam"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,1,1]]},"reference":[{"key":"e_1_3_3_2_1","unstructured":"American Veterinary Medical Association (AVMA).
