title: Analysis of intraspecific sequence variation among eight isolates of the rumen symbiont, Isotricha prostoma (Ciliophora), from two continents.
abstract: The internally transcribed spacer regions 1 and 2 (ITS-1 and ITS-2) and the 5.8S ribosomal RNA gene of Isotricha prostoma were examined for intraspecific sequence variation. There were no differences in the ITS-1/5.8S/ITS-2 region among cattle and sheep isolates of I. prostoma from Australia, Canada, and the United States, indicating that this region is 100% conserved among eight isolates from two continents.
