| 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 |
| the occurrence of antibody to bluetongue virus in new south wales. i. statewide surveys of cattle and sheep. | two state-wide surveys were carried out in 1978 to detect bluetongue (blu) virus antibody in cattle and sheep sera in new south wales (nsw). the first survey showed that blu group antibody in cattle 18-24 months old was confined to the coastal regions (east of the great dividing range) and the hunter valley. however, in the second survey, of cattle more than 5 years old, reactors were much more widely distributed over the north-eastern third of the state and into the western division with preval ... | 1988 | 2856014 |
| the occurrence of antibody to bluetongue virus in new south wales. ii. coastal region and age distribution surveys. | three surveys of cattle for bluetongue (blu) antibody were conducted over the years 1978-1980 in coastal areas of new south wales. in each survey the samples were identified by age. the prevalence of blu-group antibody, demonstrated in a gel diffusion precipitin test, was highest in the north and decreased progressively to the south. antibody prevalence increased with age. however, according to variations in prevalence by age and region, it was concluded that the activity of relevant viruses was ... | 1988 | 2856015 |
| bluetongue and related viruses in new south wales: isolations from, and serological tests on samples from sentinel cattle. | sentinel cattle at a number of localities in northern and central coastal new south wales were sampled over the summer and autumn seasons of the years 1979, 1980 and 1981. a total of 118 orbiviruses were isolated; 99 were of the palyam group, 15 were of the epizootic haemorrhagic disease (ehd) of deer group, and 4 of the bluetongue group. the palyam group viruses were identified by serotype as 68 bunyip creek, 23 csiro village, 7 d'aguilar and one was not typed. the ehd viruses were identified a ... | 1988 | 2856016 |
| serological studies of australian and papua new guinean cattle and australian sheep for the presence of antibodies against bluetongue group viruses. | following isolation of a virus (csiro19) from insects in australia and its identification as bluetongue virus serotype 20 (btv20), a nationwide survey of antibodies in cattle and sheep sera was undertaken. initial studies using the serum neutralization (sn) test showed that the distribution of btv20 antibodies in cattle was confined to the northern part of australia. group-reactive antibody tests (agar gel diffusion precipitin, agdp, and complement-fixation, cf) showed group-reactive cattle sera ... | 1983 | 6306901 |
| bluetongue and douglas virus activity in new south wales in 1989: further evidence for long-distance dispersal of the biting midge culicoides brevitarsis. | | 1995 | 7661825 |
| bluetongue and douglas virus activity in new south wales in 1989: further evidence for long-distance dispersal of the biting midge culicoides brevitarsis. | infection of cattle with bluetongue and douglas viruses was detected on the central and southern coast of new south wales from january to april 1989. bluetongue virus infection was found well south of areas of expected occurrence. evidence is presented to support wind-borne dispersal of infected vectors, culicoides brevitarsis, southwards from the hunter valley. | 1995 | 7779035 |
| laboratory and field studies of an antigen capture elisa for bluetongue virus. | an improved bluetongue antigen capture elisa (btace) technique was evaluated for its ability to detect the full range of 24 bluetongue (blu) serotypes. the btace detected all 24 serotypes in cell culture fluids, including eight serotypes where the representative strains originated from both australia and also from the south african reference collection. the amount of infectious virus required to obtain a positive btace result varied between 100-1000 tcid50. this was approximately 10-fold more se ... | 2000 | 10716347 |
| models for the dispersal in australia of the arbovirus vector, culicoides brevitarsis kieffer (diptera: ceratopogonidae). | culicoides brevitarsis is the main biting midge responsible for the transmission of bluetongue and akabane viruses to livestock in australia. models are given for its dispersal after winter from endemic areas at the southern limit of its distribution in new south wales (nsw); the models might also be applicable elsewhere. model 1 shows that dispersal can be explained by distance from a key point just outside the endemic area in mid-northern/northern coastal nsw. the model provides probability da ... | 2000 | 11087955 |
| population genetic structure and potential incursion pathways of the bluetongue virus vector culicoides brevitarsis (diptera: ceratopogonidae) in australia. | culicoides brevitarsis is a vector of the bluetongue virus (btv), which infects sheep and cattle. it is an invasive species in australia with an assumed asian/south east asian origin. using one mitochondrial marker (i.e., part of the cytochrome oxidase subunit i gene) and six nuclear markers, we inferred population genetic structure and possible incursion pathways for australian c. brevitarsis. nine mitochondrial haplotypes, with low nucleotide sequence diversity (0.0-0.7%) among these, were ide ... | 2016 | 26771743 |
