Two unidentified viral isolates from the tick, Ornithodoros coriaceus, the probable vector of the causative agent of epizootic bovine abortion, did not cause any untoward reactions in pregnant heifers which were experimentally inoculated or which were exposed to bites of O coriaceus that had been infected with cultures of the two isolates. Seemingly, neither viral isolate is involved in the cause of epizootic bovine abortion.
