虽然长臂猿（长臂猿科）是典型的一夫一妻制，一妻多夫的群体经常发生。压力与一妻多夫群体中的雄性之间的群体内竞争升高可能会增加对传染病的易感性。为了更好地了解这种相互作用，以及提供第一次全面评估寄生在自由放养的长臂猿，我们的特点是丰富的胃肠道寄生虫，并检查其患病率在男性从14组（10对生活，4多男性）的白手长臂猿（长臂猿大）在考艾国家公园，泰国。从2008年9月至2009年5月，收集了324个粪便样本，从23个单独可识别的雄性长臂猿和筛选胃肠道蠕虫和原虫分离后，通过粪便漂浮，沉淀，免疫荧光抗体检测。共回收了10种寄生虫，包括7种线虫、2种原生动物和1种吸虫。寄生虫的丰富性和物种特异性的患病率进行了检查相对于社会组织（对生活与多男性），男性地位（主要与次要），年龄（亚成年，成年，老年人），粪便糖皮质激素水平，和一年中的时间。寄生虫丰富度和社会人口或生理因素之间没有关系。同样，寄生虫感染的流行率与大多数社会人口因素无关;然而，Ternidens SP.和Balantidium coli季节性变化，鞭虫属随着年龄的增长而下降。此外，观察数据表明，竞争是低的，在这个gigabulum人口，我们的研究结果是一致的，合作防御可能会抵消压力，降低感染的易感性。
Although gibbons (family Hylobatidae) are typically monogamous, polyandrous groups occur regularly. Stress associated with elevated intragroup competition among males in polyandrous groups may increase susceptibility to infectious disease. To better understand this interplay, as well as to provide the first comprehensive assessment of parasitism in free-ranging gibbons, we characterized the richness of gastrointestinal parasites and examined their prevalence in males from 14 groups (10 pair-living, 4 multi-male) of white-handed gibbons (Hylobates lar) at Khao Yai National Park, Thailand. From September 2008 to May 2009, 324 fecal samples were collected from 23 individually recognizable male gibbons and screened for gastrointestinal helminths and protozoa after isolation via fecal floatation, sedimentation, and immunofluorescent antibody detection. A total of 10 parasite species recovered, including seven nematodes, two protozoans, and one trematode. Parasite richness and species-specific prevalence were examined relative to social organization (pair-living vs. multi-male), male status (primary vs. secondary), age (subadult, adult, senior), fecal glucocorticoid levels, and time of the year. No relationship was found between parasite richness and sociodemographic or physiological factors. Similarly, prevalence of infection with parasite species was not associated with the majority of sociodemographic factors; however, Ternidens sp. and Balantidium coli varied seasonally and Trichuris sp. decreased with increasing age. Moreover, observational data suggest that competition is low in this gibbon population, and our findings are consistent with those observations in that cooperative defense may offset stress and reduce susceptibility to infection.
