| congenital bovine epizootic arthrogryposis and hydranencephaly in australia. distribution of antibodies to akabane virus in australian cattle after the 1974 epizootic. | at the end of the 1974 epizootic of bovine congenital arthrogryposis and hydranencephaly in south-eastern new south wales, an australia-wide serological survey (about 4,000 serums) was made to determine the ditribution of cattle possessing serum neutralising antibodies against akabane virus. eighty per cent of the serums from cattle in northern australia (western australia, northern territory, and queensland) were positive. a detailed study in the epizootic area in new south wales (particularly ... | 1976 | 1016149 |
| bluetongue, epizootic haemorrhagic disease of deer and related viruses: current situation in australia. | since 1975 3 serotypes of bluetongue (bt) virus (btv) have been identified in australia: btv1 (csiro156), btv20 (csiro19) and btv21. at present 2 further bt viruses (dpp90 and dpp192) have been isolated from the blood of healthy cattle in the northern territory (nt) and are undergoing identification. there is serological evidence for btv15 infection in western australia (wa) and the nt, and a background level of serological activity to btv serotypes 1 to 17. in addition, over 50 isolations of ep ... | 1985 | 2989863 |
| epidemiology of bluetongue in australia: the vertebrate hosts. | ruminants became established in australia after european settlement which commenced in the late 18th century. bluetongue (bt) disease has never been suspected in cattle or sheep in this country. the species of ruminants found to have antibodies to bt and epizootic haemorrhagic disease (ehd) viruses are cattle, buffaloes, deer, goats and sheep. no antibodies have been found in pigs, horses, marsupials (kangaroos and wallabies) or humans, even in areas of high prevalence of bt and ehd infection. t ... | 1985 | 2989897 |
| vectors of bluetongue virus in australia. | two of the 5 serotypes of bluetongue virus (btv) known from australia have been isolated from field collected insects. serotype 20 was isolated in 1975 from a mixed pool of 214 insects containing several culicoides species. serotype 1 has been isolated from c. (avaritia) fulvus sen & das gupta collected at beatrice hill in the northern territory and from c. (avaritia) brevitarsis kieffer collected at peachester in southeast queensland. all other isolates of bluetongue (bt) group viruses have bee ... | 1985 | 2989850 |
| characterisation of wongorr virus, an australian orbivirus. | sequence analyses of vp3 gene segments of wongorr virus isolates from the northern territory of australia were compared with the cognate gene segments from picola and paroo river viruses. previous serological investigations had demonstrated some relationships between these viruses, however vp3 gene sequence and phylogenetic analyses placed these viruses within the same serogroup which was distinct from other described orbivirus serogroups. a polymerase chain reaction (pcr) was developed for the ... | 1996 | 8879140 |
| phylogenetic characterisation of bluetongue viruses from naturally-infected insects, cattle and sheep in australia. | the polymerase chain reaction was used to detect the presence of bluetongue virus (btv) in a number of clinical and insect samples collected in the northern territory of australia. sequence analyses of the amplified btv genes differentiated endemic australian and exotic viruses. two potential exotic btv were detected as a result of pcr analyses of blood from sentinel animals and of the insect vector, culicoides wadai. the detection of btv in c wadai was the first direct demonstration of the pres ... | 1994 | 8048903 |
| isolation of arboviruses from insects collected at beatrice hill, northern territory of australia, 1974-1976. | between october 1974 and may 1976, 57 596 mosquitoes, 169 957 culicoides, 5923 lasiohelea and 1043 phlebotomines were collected for virus isolation at beatrice hill (lat. 12 degrees 39's.,long. 131 degrees 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: culex annuli ... | 1984 | 6152599 |
| equine onchocerciasis in queensland and the northern territory of australia. | investigations were conducted on the taxonomy, distribution in the carcase, pathology and transmission of onchocerca spp. in equids from queensland and the northern territory. examination of small groups of horses and ponies revealed high infection rates with o. cervicalis, while lesser numbers were infected with o. gutturosa. o. reticulata was not found. neither of the australian species is likely to be of economic importance to the horsemeat industry. the findings support the belief that o. ce ... | 1983 | 6639515 |
