Abstract: | The occurrence, morphological properties, urease and alpha-amylase activities of Selenomonas ruminantium were investigated in calves in the period of milk nutrition. The average number of the organisms was found to range between 10(7) and 10(8) per 1 millilitre of rumen contents. The alpha-amylase activity of the Selenomonas strains ranged from 0.1 to 8.8 ncat.ml-1 whereas their urease activity ranged from 6.3 to 261 ncat.ml-1 of nutrient medium. The presence of morphologically typical Selenomonas ruminantium and spontaneous formation of spheroplasts were found by electron microscopic examination. |
