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 ...200818973445

flavivirus isolations from mosquitoes collected from western cape york peninsula, australia, 1999-2000.after the 1st appearance of japanese encephalitis virus (je) on mainland australia in 1998, a study was undertaken to investigate whether je had become established in enzootic transmission cycles on western cape york peninsula. adult mosquitoes were collected during the late wet season from kowanyama and pormpuraaw in april 1999, and pormpuraaw and barr's yard in april 2000. despite processing 269,270 mosquitoes for virus isolation, no isolates of je were obtained. however, other flaviviruses co ...200314710742
natural exposure of horses to mosquito-borne flaviviruses in south-east queensland, australia.in 2011 an unprecedented epidemic of equine encephalitis occurred in south-eastern (se) australia following heavy rainfall and severe flooding in the preceding 2-4 months. less than 6% of the documented cases occurred in queensland, prompting the question of pre-existing immunity in queensland horses. a small-scale serological survey was conducted on horses residing in one of the severely flood-affected areas of se-queensland. using a flavivirus-specific blocking-elisa we found that 63% (39/62) ...201324048209
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 ...19826299258
a case of murray valley encephalitis in a 2-year-old australian stock horse in south-east queensland.this report summarises the findings from a case of naturally-occurring murray valley encephalitis in a 2-year-old filly presenting with acute onset of depression and weakness. serum samples tested at the onset of clinical signs were negative for hendra and kunjin virus antibodies, but positive for murray valley encephalitis virus (mvev) using igm-capture elisa (1 : 300 dilution). a virus neutralisation assay performed 4 weeks later confirmed a titre of 1 : 160. sera collected in the weeks preced ...201525708787
