原麝和林麝冬夏两季粪便真菌菌群多样性

肠道微生物群对宿主健康的影响取决于饮食、环境和宿主等因素。本研究通过Illumina MiSeq平台对冬、夏两季林麝和原麝粪便真菌ITS1区段进行测序,探究原麝和林麝肠道真菌菌群结构特性及季节因素对其多样性的影响。结果表明,林麝和原麝肠道真菌组成中子囊菌门Ascomycota均为优势菌门,它们的相对丰度随物种和季节因素改变差异不显著。但原麝和林麝肠道真菌在α-多样性指数和β-多样性差异显著,表明林麝和原麝肠道真菌结构存在较大差异。此外,研究还表明原麝冬季肠道真菌多样性高于夏季,且菌群丰富度存在显著差异。受季节因素影响,原麝肠道真菌中被孢霉门Mortierellomycota存在显著差异。该研究是国内外首次对原麝肠道真菌组成进行探究,这些结果为改善麝种群的饲养水平提供了理论依据,并为更科学地人工饲养奠定了基础。

Fungal diversity of Siberian musk deer and forest musk deer feces in winter and summer

The influence of gut microbiota on host health depends on factors such as diet, environment, and host. Illumina MiSeq platform was used to sequence the ITS segment of the fecal fungi of Siberian musk deer and forest musk deer in winter and summer in order to explore the structural characteristics of fungal community and determine the influence of seasonal factors on the fungal diversity. The results showed that Ascomycota in the feces of forest musk deer and Siberian musk deer was dominant, and the relative abundance was not significantly differernt in both animal species and nearly unchanging seasonally. However, the both animals showed great differences in fungal α-diversity and β-diversity. It was also showed that the diversity of fungi in the feces of Siberian musk deer and forest musk deer in winter was higher than that in summer, and there were significant differences in the richness of the microbiota. Seasonally, the relative abundances of Mortierellomycota in the gut fungi of Siberian musk deer were significantly different. This is the first report on the composition of the fungal community in the feces of Siberian musk deer, providing reference for searching the nutritional level of musk deer.
