The rumen microbiota of reindeer (Rangifer tarandus) with clinical manifestations of necrobacteriosis

Necrobacteriosis is an infectious disease that affects many species of domestic and wild mammals, birds, and humans. The main clinical manifestations of the disease are associated with the development of purulent-necrotic lesions of the skin, mucous membranes, internal organs, and extremities as a result of infection of the host organism by strictly anaerobic pathogenic fuzobacteria, the Fusobacterium necrophorum . For reindeer herding, the problem of necrobacteriosis among other diseases of reindeer is one of the most significant, since it brings the most significant damage to the economic activity of the population of the Russian Arctic. This paper for the first time shows the obtained results on rumen microbiota composition differences between the clinically healthy Rangifer tarandus reindeer of the Russian Arctic and reindeer with necrobacteriosis. The purpose of the study was to characterize the distinctive features of rumen microbiota in the reindeer with the clinical manifestations of necrobacteriosis...
