为了进一步开发与应用元宝枫籽油,研究了元宝枫籽油对高脂膳食小鼠脂代谢及肠道健康的影响。将60只小鼠分为空白组、模型组、元宝枫籽油高剂量组〔1 200 mg/(kg·d)〕和低剂量组〔600 mg/(kg·d)〕,连续灌胃60 d。实验结束后,测定小鼠生长状况、血脂水平、盲肠微环境指标和盲肠内容物短链脂肪酸及微生物菌群。结果表明:与模型组相比,元宝枫籽油高剂量组能显著降低小鼠体质量、腰围、Lee′s指数、腹腔脂肪质量,显著降低小鼠盲肠内容物中游离氨、氨态氮、硫化氢和pH,显著增加盲肠内容物中丁酸 ...

动物肠道中寄生着数以亿计的微生物,参与到动物机体中如代谢和免疫等重要的生理过程中。然而,在粪便等复杂样本中包含着大量微生物,无法通过纯培养技术进行研究,无法评估样本中的微生物多样性。通过宏基因组学技术可以对微生物群总DNA进行分析,使其成为目前研究复杂样本微生物结构和功能的重要工具。并且伴随高通量测序技术和生物信息学的进步,对微生物的分析流程也在不断地被改进。本文比较了在宏基因组学中普遍应用的标志基因扩增子分析和全宏基因组分析,对宏基因组技术在几类野生脊椎动物肠道微生物领域中的应用进行综述 ...

高原鼠兔和高原鼢鼠是青藏高原的两种优势小型哺乳动物,其肠道微生物在宿主高原适应性方面发挥着重要作用,同时,作为野生动物,它们的肠道微生物也可能携带抗生素抗性基因并将其传播给人类,造成抗生素药物失效。因此,对这两个物种肠道微生物组和抗生素抗性基因的研究十分重要。本研究通过16S rRNA基因测序,定量PCR等技术获得两物种肠道菌群特征并检测到了抗生素抗性基因。结果发现,在门水平上,高原鼢鼠肠道拟杆菌门(Bacteroidetes)的相对丰度更高;而高原鼠兔肠道厚壁菌门(Firmicutes)和放线菌门 ...

Natural training enclosure design schematic. We selected 12 sika deer including six adults and six sub‐adults. Key considerations in the design of the natural training were to divide the training spatial ground into two parts (30 × 30 m small areas for isolation of new individuals and large areas measuring 200 × 600 m for free walking), and the ...
