| antibodies to akabane virus in australia. | neutralising antibody to akabane virus was shown to develop in cattle in northern australia throughout the year and also on the east coast of new south wales in the summer during 1975/1976. other species found to have antibody to akabane virus were buffaloes, horses, camels and sheep, but no antibody was found in domestic chickens, ducks, wallabies or man. the biting midge culicoides brevitarsis has been detected in all the major areas where antibody was demonstrated in this study. | 1978 | 655964 |
| a survey of antibody to aino virus in cattle and other species in australia. | a serological survey of healthy cattle in australia showed that antibodies to aino virus were present in serums from cattle in northern australia and down the east coast as far as central new south wales in 1975, 1976 and 1977, but occurred with a lower frequency than antibodies to akabane virus. in contrast to the findings with akabane virus, no neutralising antibodies to aino virus were detected in serums from camels, dogs or horses. antibodies to both viruses were detected in buffaloes and sh ... | 1978 | 718555 |
| 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 |
| influences of vector biology on transmission of arboviruses and outbreaks of disease: the culicoides brevitarsis model. | the use of a model to appraise arboviral epizootics is described, and examples are given which demonstrated long-distance wind-dispersal of the biting-midge vector culicoides brevitarsis from the same endemic source. vector abundance is characterised by peaks and troughs of abundance, the patterns of which vary between localities and annually. short term climatic effects can change rapidly the age structure of a population, thus increasing the number of midges that can transmit a virus and profo ... | 1995 | 8545983 |
| 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 |
