摘要： BackgroundEndometritis is a uterine infection caused by bacterial pathogens and has detrimental effects on productive and reproductive performance in dairy cows. A large number of studies have demonstrated the association of gut microbiota with infectious diseases. However, the role of gut microbiota in dairy cows with endometritis is still poorly understood.ResultsIn the present study, we characterized the fecal microbial populations in the dairy cows suffering from metritis (n = 10) and healthy cows (n = 9) using the 16 S rRNA gene sequencing. Results revealed an increased abundance of Firmicutes and Bacteroidetes in the affected cows indicating the potential role of these two bacterial taxa in the pathogenesis of endometritis. The Ruminococcaceae_UCG-005 was the predominant genus while Olsenella and Succinivibrio were the most abundant genera in the cows affected with metritis. Further, the association of specific genera from Firmicutes and Bacteroidetes indicated three co-occurrence groups indicating the potential interaction of these genera in modulating the immune response, dysbiosis and inflammatory reaction. In addition, a significantly higher abundance of genes involved in the excretory system was observed in affected cows.ConclusionsOur findings provide evidence of changes in gut microbiota composition in cows suffering from metritis and advocate the need to explore the effect of commensal gut bacteria specifically co-occurring taxa in uterine inflammation and infection.
