Resumen:
Host-rumen-microbe interactions are essential components of many physiological processes, and therefore can
affect ruminant health. Classical knowledge of rumen microbiology is based on culture-dependent methodologies,
which only account for 10–20% of the rumen bacterial communities. While, the advancement in DNA
sequencing and bioinformatics platforms provide novel approaches to investigate the composition and dynamics
of the rumen microbiota. Recent studies demonstrated that the ruminal ecosystem is highly diverse and harbors
numerous microbial communities. The composition of these microbial communities are affected by various
environmental factors such as nutrition and different management strategies. Disturbance in the microbial
ecology of the rumen is associated with the development of various diseases. Despite the flow of recent rumenbased
studies, rumen microbiota is still not fully characterized. This review provides an overview of recent
efforts to characterize rumen microbiota and its potential role in rumen health and disease. Moreover, the recent
effects of dietary interventions and probiotics on rumen microbiota are discussed.
