title: Occurrence of the Rumen Ciliate Oligoisotricha bubali in Domestic Cattle (Bos taurus).
abstract: Oligoisotricha bubali, previously observed twice in water buffalo, was detected in rumen contents of domestic cattle (Bos taurus) in two different areas of Tennessee. Concentrations ranged from <1 to 35% of the total protozoa in unweaned calves and up to 72% in older animals in feedlot. In contrast to the other genera of holotrichs, both total numbers and percent composition of O. bubali increased when animals were fed a corn silage-concentrate diet.
