摘要: 本研究旨在利用宏基因组学深入分析上海某鸽场青年鸽(RP)和产鸽(LP)粪便样品的微生物菌群差异。结果显示,肉鸽肠道菌群的优势菌门为厚壁菌(Firmicutes)、变形菌(Proteobacteria)和放线菌(Actinobacteria)。RP组中双歧杆菌(Bifidobacterium)、棒状杆菌(Corynebacteriun)、嗜冷杆菌(Psychrobacter)、链球菌属(Streptococcus)含量显著高于LP组,而LP组金黄色葡萄球菌属(Staphyloccus)、短状杆菌属(Brachybacterium)、库特氏菌属(Kurthia)和埃希氏菌属(Escherichia)含量显著高于RP组。LEfSe分析显示,LP和RP组的差异表达基因主要富集于5个KEGG通路。抗生素耐药基因(antibiotic resistance genes,ARGs)鉴定显示,肉鸽体内存在198种ARGs,其中多重耐药类ARGs流行率40%以上,说明该场肉鸽抗生素耐药情况较严重。本研究为后续深入研究肠道菌群与健康养殖、抗生素耐药机制等提供了科学数据。

Abstract: In this study, metagenomics was used to explore the fecal microbiota differences between the young pigeons (RP) and older pigeons (LP). The results showed that Firmicutes, Proteobacteria and Actinobacteria were the dominant bacterias. The contents of Bifidobacterium, Corynebacteriun, Psychrobacter and Streptococcus in RP group were significantly higher than those in LP group, while the relative abundance of Staphyloccus, Brachybacterium, Kurthia and Escherichia in LP group were significantly higher than those in RP group. Further LEfSe analysis showed that the differentially expressed genes in the two groups were enriched in 5 KEGG pathways. Antibiotic resistance genes (ARGs) analyzation showed that a total of 198 ARG,were identified. And the prevalence rate of multi-drug ARGs was more than 40%, which indicated that the antibiotic resistance problem in pigeon is seriously. The current study provided scientific datas for further researches on gut microflora and healthy breeding, and mechanism of antibiotic resistance mechanism.
