      High-grain feeding used in the animal production is known to affect the host rumen bacterial community, but our understanding of consequent changes in goats is limited. This study was therefore aimed to evaluate bacterial population dynamics during 20 days adaptation of 4 ruminally cannulated goats to the high-grain diet (grain: hay e ratio of 40:60). The dietary transition of goats from the forage to the high-grain-diet resulted in the significant decrease of rumen fluid pH, which was however still higher than value established for acute or subacute ruminal acidosis was not diagnosed in studied ...

    • Pseudobutyrivibrio xylanivorans adhesion to epithelial cells

      The ruminal bacteria Pseudobutyrivibrio xylanivorans strain 2 (P. xylanivorans 2), that mediates the digestion of plant fiber, is considered an attractive candidate for probiotics. Adherence to the epithelium of the digestive tract of the host is one of the major requirements for probiotics. In this study, we assessed the adhesion of P. xylanivorans 2 to SW480 cells and characterized this process utilizing multiple microscopy approaches. Our results indicate that a multiplicity of infection of 200 CFU/cell allows the highest bacteria to cell binding ratio, with a lower percentage of ...
