Study on the Gut Microbial Diversity of Leucogeranus leucogeranus and Anser cygnoides in Farmland Habitats Around Poyang Lake
In order to understand the gut microbial diversity of Leucogeranus leucogeranus and Anser cygnoides in the farmland habitats of Poyang Lake,200 fecal samples of Leucogeranus leucogeranus and Anser cygnoides from Wuxing Reclamation Farm and Kangshan Reclamation Farm were examined using high-throughput sequencing technology.The re-sults showed that Firmicutes was the absolute dominant bacteria phylum in the gut microbiota of Leucogeranus leucogera-nus,while Firmicutes and Proteobacteria were the absolute dominant bacteria phylum in the gut microbiota of Anser cygnoi-des.The gut microbial diversity of Leucogeranus leucogeranus was lower than that of Anser cygnoides,and the gut micro-bial structures of the two species were significantly different.Leucogeranus leucogeranus and Anser cygnoides carried a to-tal of 184 species of pathogens,including animal pathogens,zoonotic pathogens,and plant pathogens.The species and quantity of pathogens carried by Leucogeranus leucogeranus were less than those carried by Anser cygnoides.Streptococ-cus gallolyticus subsp.pasteurianus,Enterococcus faecium,and E.casseliflavus were the main pathogens carried by the two species of birds.The results of this study provide a basis for understanding the gut microbial structure of wintering mi-gratory birds in Poyang Lake,and have certain reference value and practical significance for the development of conserva-tion and management strategies for wintering migratory birds.
