哺乳动物的肠道微生物对宿主的新陈代谢是无价的，但很少有研究人员研究野生哺乳动物在自然条件下的肠道微生物动力学。本研究旨在通过调查两种野生狐猴肠道微生物组的自然变异来填补这一知识空白，这两种野生狐猴是狐猴和灰狐猴。还将野生卡塔与圈养种群进行比较，以辨别物种内栖息地的影响。从马达加斯加和维也纳动物园收集的粪便样本中提取肠道微生物DNA，并进行测序。野生和圈养的卡塔有不同的微生物群落，这可能是由于它们种群之间的饮食和发育的差异。由于微生物丰度的变化，而不是组成的变化，野生卡塔和白纹伊蚊也有不同的肠道微生物群。在每一种狐猴中，个体之间以及从旱季到雨季的差异都很大。种内和时间上的微生物变化需要更多的研究，饮食的变化可能是原因之一。(C)2015年5.卡格尔股份公司，巴塞尔
Mammalian gut microbes are invaluable to the host's metabolism, but few researchers have examined gut microbial dynamics under natural conditions in wild mammals. This study aims to help fill this knowledge gap with a survey of the natural variation of the gut nnicrobiome in 2 wild lemur species, Lemur catta and Propithecus verreauxi. The wild L. catta were also compared to a captive population to discern the effect of habitat within a species. Gut microbial DNA was extracted from fecal samples collected in Madagascar and the Vienna Zoo and sequenced. The wild and captive L. catta had distinct microbial communities, likely due to differences in diet and development between their populations. The wild L. catta and P. verreauxi also had distinct gut microbiomes, due to a change in microbial abundance, not composition. Within each lemur species, there was abundant variation between individuals and from the dry to the wet season. The intraspecific and temporal microbial variation requires more investigation, with changes in diet a likely contributor. (C) 2015 5. Karger AG, Basel
