传染病传播是人类和其他动物社会性的代价。然而，人们对社会行为与感染风险之间的联系机制知之甚少。我们进行了一项现场实验，以研究宿主的内在特征，行为和生理如何影响非人灵长类动物感染胃肠道寄生虫。我们测量率再感染的社会群体的红顶白眉猴，Cercocebus torquatus，化疗治疗寄生虫感染。通过测量行为，感染和糖皮质激素水平，我们比较了空间共享，定向接触和生理压力对获得新感染风险的相对影响。我们发现，在邻近网络中，处于中心位置、联系良好且倾向于转换群体的个体感染蠕虫的风险增加。然而，原生动物感染在整个人群中更为均匀。一般来说，在社会网络中的位置，特别是空间共享似乎比生理压力或宿主特征的免疫抑制作用更重要，以确定感染的风险。我们的研究结果表明，野生动物种群内的疾病生态学的未来研究应该集中在网络协会的措施，除了个别主机的特点。(C)2016动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Infectious disease transmission is a cost of sociality in humans and other animals. Nevertheless, the mechanisms linking social behaviour to infection risk are poorly known. We conducted a field experiment to examine how host intrinsic traits, behaviour and physiology affect infection of nonhuman primates with gastrointestinal parasites. We measured rate to reinfection in a social group of red-capped mangabeys, Cercocebus torquatus, following chemotherapeutic treatment for parasite infections. By measuring behaviour, infection and glucocorticoid levels, we compared the relative effects of space sharing, directional contact and physiological stress on risk of acquiring new infections. We found that, within proximity networks, individuals that were central, well connected and had a tendency to switch groups were at increased risk of infection with helminths. Protozoan infections, however, were acquired more uniformly across the population. In general, position in the social network and, in particular, space sharing appears to be more important than the immunosuppressive effects of physiological stress or host traits in determining risk of infection. Our results suggest that future studies of disease ecology within wildlife populations should focus on measures of network association in addition to individual host traits.
