| No relation was shown by neutralization or complement-fixation tests to arboviruses isolated in Australia [7] . Strains of bovine ephemeral fever isolated in Australia, South Africa and Japan were shown indistinguishable [7] , [12] , [19] . | Three recently registered viruses isolated in Australia, were shown to be antigenically related to BEF virus by CF, IFA, and NT. Those three viruses, Adelaide River, Berrimah and Kimberly, plus BEF virus now comprise the newly- formed BEF serogroup. For additional information, see Reference [32] and the registration cards for Adelaide River, Berrimah and Kimberly viruses. | |
