The objective of this study was to determine if the odour of hamsters, infected with <jats:italic>Le. infantum<\/jats:italic>, was more attractive than the odour of the same hamsters, before they were infected. The attractiveness of odour collected from individual hamsters (n\u2009=\u200913), before they were infected, was compared in a longitudinal study, with the attractiveness of the odour of the same hamster in a Y-tube olfactometer bioassay, at a late stage of infection. The odour of six of the golden hamsters was significantly more attractive to 50% of the female sand flies at the end of infection compared to before infection and the odour of four of the golden hamsters was significantly more attractive to 75% of the female sand flies at the end of infection. These results strongly indicate that hamsters infected with <jats:italic>Le. infantum<\/jats:italic> become significantly more attractive to a greater proportion of female sand flies as the infection progresses.<\/jats:p>","DOI":"10.1038\/s41598-017-06313-w","type":"journal-article","created":{"date-parts":[[2017,7,17]],"date-time":"2017-07-17T09:08:36Z","timestamp":1500282516000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["After infection with Leishmania infantum, Golden Hamsters (Mesocricetus auratus) become more attractive to female sand flies (Lutzomyia longipalpis)"],"prefix":"10.1038","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0592-6542","authenticated-orcid":false,"given":"T.
