摘要: 本研究旨在了解患呼吸道疾病羊鼻腔及其所在羊舍地面表层堆积物的微生物多样性,分析羊患呼吸道疾病与羊生活环境中菌群结构之间的联系,为羊呼吸系统疾病的预防和治疗提供参考。本课题采集宁夏回族自治区银川市某羊养殖场羊鼻腔拭子及羊舍地面表层堆积物,以健康羊鼻腔拭子及健康羊所在羊舍地面表层堆积物为对照,进行16S rRNA基因测序,通过生物信息学技术分析健康羊鼻腔及其生活环境与患呼吸道疾病羊鼻腔及其生活环境中微生物菌群的群落结构及多样性。结果显示:与健康羊鼻腔及其生活环境中微生物相比,患呼吸道疾病羊鼻腔及其生活环境中微生物菌群的多样性和丰富度均降低。健康羊鼻腔与患呼吸道疾病羊鼻腔具有不同的群落结构,二者之间具有极显著的差异(P<0.01),寡养单胞菌属(Stenotrophomonas)是健康羊鼻腔中主要的菌属,莫拉菌属(Moraxella)、伯杰菌属(Bergeyella)和丝状杆菌属(Filobacterium)是患呼吸道疾病羊鼻腔中的优势菌属。此外,支原体属(Mycoplasma)、波氏杆菌属(Bordetella)和曼氏杆菌属(Mannheimia)等细菌性病原在患呼吸道疾病羊鼻腔的相对丰度也明显增加。健康羊所在羊舍地面表层堆积物与患呼吸道疾病羊所在羊舍地面表层堆积物的菌群结构也具有显著差异(P<0.05),厚壁菌门(Firmicutes)是患呼吸道疾病羊所在羊舍地面表层堆积物中的优势菌门。结果提示,患呼吸道疾病羊鼻腔及其生活环境中微生物菌群结构及空间分布发生了显著变化,但羊生活环境中微生物群落结构与羊患呼吸道疾病无直接关联,患呼吸道疾病羊鼻腔中莫拉菌属、伯杰菌属和丝状杆菌属等病原菌相对丰度的增加及微生物菌群失衡可能是导致羊患呼吸道疾病的重要因素。

Abstract: This experiment was conducted to understand the microbial diversity of the nasal cavity of sheep with respiratory disease and the surface deposits of their house, and analyze the relationship between the respiratory diseases of sheep and the microbial community composition of their environment. Our study is expected to provide references for prevention and treatment of sheep respiratory diseases. We collected the nasal swabs of sheep and the surface deposits of their house from a sheep farm in Yinchuan, Ningxia. Then, control with nasal swabs and surface deposits of the healthy sheep, 16S rRNA gene sequencing were performed, and the microbial community composition of the nasal cavity and the environment of healthy sheep with respiratory disease were analyzed by bioinformatics. The results showed that the diversity and richness of microbial flora in the nasal cavity and their environment of sheep with respiratory diseases were reduced compared with those healthy sheep. The microbial community composition of the nasal cavity in healthy sheep was significantly different from those sheep with respiratory diseases (P<0.01). Stenotrophomonas is the main genus in the nasal cavity of healthy sheep. Moraxella, Bergeyella and Filobacterium are the predominant genus in the nasal cavity of sheep suffering from respiratory diseases. The microbial community composition in the surface deposits of house between the healthy and the sheep with respiratory diseases also had a significant difference (P<0.05). Firmicutes was the most prominent phyla in diseased sheep. It is concluded that the microbial community composition and relative abundance were changed in the nasal cavity and their environment of sheep with respiratory diseases, but the environment microbial community is not directly related to the respiratory disease of sheep. The imbalance of microbial flora and the increased relative abundance of bacterial pathogens such as Moraxella, Bergeyella, and Filobacterium in diseased sheep may be important factors leading to respiratory diseases in sheep.

Key words: respiratory disease of sheep, nasal microbial community, surface deposits of sheep house, diversity
