| variation in arbovirus infection rates in species of birds sampled in a serological survey during an encephalitis epidemic in the murray valley of south-eastern australia, february 1974. | there was extensive and exuberant breeding of waterbirds before and during an epidemic of arboviral encephalitis in the murray valley of south eastern australia in 1974. as estimated by haemagglutination inhibition tests on 432 bird sera collected between 4th and 13th february, 1974, infection with murray valley encephalitis virus, kunjin virus and possibly other flaviviruses was concentrated in species of the order ciconiiformes (55% positive) and pelecaniformes (41%), compared with only 5% in ... | 1982 | 6299259 |
| kunjin virus: an australian variant of west nile? | kunjin (kun) is a flavivirus in the japanese encephalitis antigenic complex that was first isolated from culex annulirostris mosquitoes captured in northern australia in 1960. it is the etiological agent of a human disease characterized by febrile illness with rash or mild encephalitis and, occasionally, of a neurological disease in horses. kun virus shares a similar epidemiology and ecology with the closely related murray valley encephalitis (mve) virus, the major causative agent of arboviral e ... | 2001 | 11797773 |
| role of enhanced vector transmission of a new west nile virus strain in an outbreak of equine disease in australia in 2011. | in 2011, a variant of west nile virus kunjin strain (wnvkun) caused an unprecedented epidemic of neurological disease in horses in southeast australia, resulting in almost 1,000 cases and a 9% fatality rate. we investigated whether increased fitness of the virus in the primary vector, culex annulirostris, and another potential vector, culex australicus, contributed to the widespread nature of the outbreak. | 2014 | 25499981 |
| viruses recovered from mosquitoes and wildlife serum collected in the murray valley of south-eastern australia, february 1974, during an epidemic of encephalitis. | pools of mosquitoes collected in the murray valley in february, 1974, during an encephalitis epidemic yielded 239 isolates of 11 distinct viruses. these included 39 isolates of mve virus, an incriminated causative agent of encephalitis in man, and 111 isolates of kunjin virus, a probable causative agent. an additional isolate of mve virus was recovered from the serum of a white-faced heron, ardea novaehollandiae. the other 9 viruses comprised the alpha-viruses ross river and sindbis, the flavivi ... | 1982 | 6299258 |
| vector competence of australian mosquito species for a north american strain of west nile virus. | since the establishment of west nile virus (wnv) into the united states, concern has arisen that this virus may also pose a serious threat to australian biosecurity. the vector competence of 19 australian mosquito species for a north american strain of wnv was evaluated. mosquitoes collected from cairns, brisbane, and sydney were exposed to blood containing 10(4.0+/-0.3) cell culture infectious dose(50)/mosquito wnv that was isolated from a crow during the 1999 new york outbreak. mosquitoes were ... | 2008 | 18973445 |
| australian x disease, murray valley encephalitis and the french connection. | epidemics of a severe encephalitis occurred in eastern australia between 1917 and 1925, in which over 280 cases were reported with a fatality rate of 68%. the disease had not been described previously and was called australian x disease. the next epidemic occurred in south-east australia in the summer of 1950-51. the disease was given its name of murray valley encephalitis as this was the area from which most cases were reported. a virus was isolated by eric french in victoria, and about the sam ... | 1995 | 8545982 |
