| experimental infection of culicoides brevitarsis from south-east queensland with three serotypes of bluetongue virus. | laboratory-reared c. brevitarsis (biting midges) were fed on sheep which had been experimentally infected with bluetongue serotype 1 (csiro 156), bluetongue serotype 20 (csiro 19) or bluetongue serotype 21 (csiro 154), or on cattle experimentally infected with bluetongue serotype 20 (csiro 19). approximately 77 000 c. brevitarsis were exposed to sheep and 9000 to cattle. the average percentage feeding on sheep was 54% and on cattle 47%. in attempts to transmit virus by bite 3360 c. brevitarsis w ... | 1985 | 2998313 |
| 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 |
| 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 |
