“…Only intra-serogroup reassortment has been reported (Gorman et al, 1978;Kahlon et al, 1983;Brown et al, 1988) and inter-serogroup reassortment was not demonstrated in reassortment experiments with EHD, bluetongue and Pata viruses (Brown et al, 1988). Experiments in progress with the Eubenangee, Wallal and Warrego serogroup viruses suggest that reassortment occurs within each serogroup, and only between isolates which exhibit high levels of sequence conservation.…”

SUMMARYViruses in the Eubenangee, Wallal and Warrego serogroups oforbiviruses have been isolated primarily in Australia. Several isolates in these three serogroups were examined by gel electrophoresis and blot hybridization of genomic RNA. Conserved and variant genes were identified by the degree of hybridization between cognate genes. The dsRNA profiles of isolates within a serogroup exhibited heterogeneity in polyacrylamide gels, but they were indistinguishable in agarose gels. Isolates within a serogroup generally showed a high level of cross-hybridization in eight segments with cognate segments 2 and 6 exhibiting hybridization signal variants. Although Pata virus has been classified in the Eubenangee serogroup, it was not closely related to other Eubenangee isolates by hybridization. Similarly, Mitchell River virus was not closely related to other members of the Warrego serogroup. The taxonomic status of Pata and Mitchell River viruses should be reviewed, and in the interim they should be placed in the ungrouped set of orbiviruses. Inter-serogroup relatedness was also examined by blot hybridization. Representatives from the Eubenangee, Wallal, Warrego, bluetongue, epizootic haemorrhagic disease and Corriparta serogroups were examined. Several of the serogroups were distantly related, and the low level of relatedness was suggestive of a common ancestry. While many of these serogroups may co-circulate in nature, these data suggest that each serogroup represents a distinct gene pool. The taxonomic significance of these data is discussed.

Corresponding double-stranded RNA segments ofthe related orbiviruses Wallal and Mudjinbarry produced distinctly different RNase T1 fingerprint patterns. No extensive sequence reiteration was observed between segments of Mudjinbarry virus. Fingerprint analysis of the genome of recombinant orbiviruses confirmed segment reassortment as a mechanism of interchange of genetic information. When temperature-sensitive mutants of each virus were crossed in mixed infection, a consistent pattern of segment reassortment was correlated with generation of the wild-type phenotype. Thus, the temperature-sensitive lesion of group II Wallal serogroup mutants was mapped to segment 1. The group I mutant lesion appears to be located in segment 2.

Between October 1974 and May 1976, 57596 mosquitoes, 169957 Culicoides, 5923 Lasiohelea and 1043 phlebotomines were collected for virus isolation at Beatrice Hill (lat. 12�39'S.,long. 131�20'E.) in the Northern Territory of Australia. A total of 94 viruses belonging to 22 different serological groupings was isolated. The following species of insect yielded viruses which were identified and those viruses marked with an asterisk represent a new record of insect host:

Mudjinbarry Virus, an Orbivirus Related to Wallal Virus Isolated from Midges From the Northern Territory of Australia

Abstract: A virus strain (NT14952) isolated from Culicoides marksi collected in the Alligator Rivers area of the Northern Territory of Australia in September 1971 was shown to be an orbivirus anti genically related to but distinct from Wallalvirus. The name 'Mudjinbarry virus' is suggested for it.
