山羊肠道微生物群发育与多样性分析
Development and diversity of the intestinal microbiota of goat
摘要
Abstract
To understand the development and diversity of the gut microbial community,two goats were random select-ed from different goat farms in Jiangsu Province,China.Fecal specimens of each goat were sampled in 1,3,5,10,20,30,40,45,50,60,70,80 and 90 days of age.All the samples were analyzed by metagenomic sequencing,and the re-sults indicated that the member and abundance of the goat gut microbiota was varies constantly with the goat age and in-fluenced by sucking and feeding.The gut microbiota of 40-days old lactating goats finally stabilized at about 600 species,and the 90-days old weaned goat intestinal bacterial population finally stabilized at around 1 500 species.Among the more than 80 core members,Bacteroides fragilis,Escherichia coli and Butyricicoccus pullicaecorum were the dominant bacte-ria in the gut of lactating lambs,while Prevotella ruminicola and Firmicutes bacterium were the dominant bacteria of weaned goat intestinal bacterial population.It was very noteworthy that some zoonotic bacteria,such as Shigella sonnei,Shigella boydii,Shigella flexneri,Shigella dysenteriae,Salmonella enterica,Salmonella bongori,Clostridiales bac-terium,Lactococcus garvieae and Helicobacter pylori,etc.were detected in goats,and this leads us to wonder if goats are the reservoirs of these microbes.关键词
