We experimentally treated semi-free-ranging red-capped mangabeys (\n            <jats:italic>Cercocebus torquatus<\/jats:italic>\n            ) in Nigeria with antiparasitic drugs and examined subsequent changes in glucocorticoid production and individual behaviour. Because both parasites and stress impact energy balance and health, we measured (i) behavioural time re-allocation via activity budgets, (ii) social relationships (e.g. social connectivity and dominance hierarchy stability) and (iii) body condition. We collected triplicate faecal samples (\n            <jats:italic>n<\/jats:italic>\n            = 441) from 49 individuals prior to and following treatment. Cortisol levels fluctuated in parallel with parasite abundance. Elevations in cortisol, but not parasitism, were related to reduced body condition. Behaviour also shifted according to infection status, with uninfected individuals spending more time foraging and less time resting and vigilant compared with when they were infected. Time spent feeding, travelling or socializing did not differ between pre- and post-treatment time periods. Group cohesion, but not dominance stability, changed following treatment, suggesting parasite-induced social avoidance. Together, these findings show a coordinated response to infection that promotes host tolerance through stress and energy conservation, reduces transmission risk and increases protection when infected hosts are vulnerable.\n          <\/jats:p>","DOI":"10.1098\/rspb.2016.1201","type":"journal-article","created":{"date-parts":[[2016,7,27]],"date-time":"2016-07-27T09:08:18Z","timestamp":1469610498000},"page":"20161201","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["Changes in physiological stress and behaviour in semi-free-ranging red-capped mangabeys (\n            <i>Cercocebus torquatus<\/i>\n            ) following antiparasitic treatment"],"prefix":"10.1098","volume":"283","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1664-5180","authenticated-orcid":false,"given":"Sagan","family":"Friant","sequence":"first","affiliation":[{"name":"Nelson Institute for Environmental Studies, University of Wisconsin\u00ad\u2013Madison, Madison, WI 53706, USA"},{"name":"Department of Pathobiological Sciences, School of Veterinary Medicine, University of Wisconsin\u00ad\u2013Madison, Madison, WI 53706, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toni E.","family":"Ziegler","sequence":"additional","affiliation":[{"name":"Wisconsin National Primate Research Centre, University of Wisconsin\u00ad\u2013Madison, Madison, WI 53706, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tony L.","family":"Goldberg","sequence":"additional","affiliation":[{"name":"Nelson Institute for Environmental Studies, University of Wisconsin\u00ad\u2013Madison, Madison, WI 53706, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"175","published-online":{"date-parts":[[2016,7,27]]},"reference":[{"key":"e_1_3_7_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/280361a0"},{"key":"e_1_3_7_3_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1092528"},{"key":"e_1_3_7_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature04246"},{"key":"e_1_3_7_5_2","doi-asserted-by":"publisher","DOI":"10.1890\/08-1763.1"},{"key":"e_1_3_7_6_2","doi-asserted-by":"publisher","DOI":"10.7882\/AZ.2012.008"},{"key":"e_1_3_7_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0169-4758(99)01484-2"},{"key":"e_1_3_7_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2656.2010.01742.x"},{"key":"e_1_3_7_9_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1214935"},{"key":"e_1_3_7_10_2","article-title":"Heterogeneity in pathogen transmission: mechanisms and methodology","author":"VanderWaal KL","journal-title":"Funct.
