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.
