| genetic differentiation of murray valley encephalitis virus in australia and papua new guinea. | the genetic relatedness of ten murray valley encephalitis virus (mve) isolates from australia has been examined by comparing haeiii and taqi restriction digest profiles of cdna to virion rna. the isolates were from the murray valley region of south-eastern australia and from the ord river region of western australia and spanned a period of 23 years (1951-1974). the isolates generated closely similar restriction digest profiles. the extent of similarity suggested that the level of nucleotide sequ ... | 1986 | 2884985 |
| definition of species in the culex sitiens subgroup (diptera: culicidae) from papua new guinea and australia. | japanese encephalitis is a disease of major importance in asia, which from 1995 has extended its range into the north of australia. culex annulirostris skuse of the culex sitiens subgroup of culex was incriminated as the most likely mosquito vector. because misidentifications previously have occurred within this subgroup, our paper defines electrophoretic methods to identify culex specimens from queensland and the northern territory in australia and from western province in papua new guinea. in ... | 2000 | 11004787 |
| isolation of japanese encephalitis virus from mosquitoes (diptera: culicidae) collected in the western province of papua new guinea, 1997-1998. | after japanese encephalitis (je) virus emerged in the torres strait in australia in 1995, investigations were initiated into the origin of the incursion. new guinea was considered the most likely source, given its proximity to islands of the torres strait. almost 400,000 adult mosquitoes were processed for virus isolation from 26 locations in the western province of papua new guinea (png) between february 1996 and february 1998, yielding three isolates of je virus. two isolates of murray valley ... | 2000 | 11289676 |
| population structure and dispersal of the freshwater mosquitoes culex annulirostris and culex palpalis (diptera: culicidae) in papua new guinea and northern australia. | in 1995 and 1998, outbreaks of japanese encephalitis (je) virus occurred for the first time in australia. virus isolation from pools of mosquitoes indicated culex annulirostris skuse was the most likely vector. it was hypothesized that wind-blown mosquitoes introduced je from papua new guinea to the torres strait and cape york, northern australia. this study used levels of genetic differentiation, as indirect evidence of dispersal of mosquitoes between the two continents. the results have demons ... | 2003 | 12693844 |
| mosquito host-feeding patterns and implications for japanese encephalitis virus transmission in northern australia and papua new guinea. | japanese encephalitis (je) virus spread to northern australia during the 1990s, transmitted by culex annulirostris skuse and other mosquitoes (diptera: culicidae). to determine the relative importance of various hosts for potential vectors of je virus, we investigated the host-feeding patterns of mosquitoes in northern australia and western province of papua new guinea, with particular attention to pigs, sus scrofa l. - the main amplifying host of je virus in south-east asia. mosquitoes were col ... | 2003 | 14651654 |
| application of satellite precipitation data to analyse and model arbovirus activity in the tropics. | murray valley encephalitis virus (mvev) is a mosquito-borne flavivirus (flaviviridae: flavivirus) which is closely related to japanese encephalitis virus, west nile virus and st. louis encephalitis virus. mvev is enzootic in northern australia and papua new guinea and epizootic in other parts of australia. activity of mvev in western australia (wa) is monitored by detection of seroconversions in flocks of sentinel chickens at selected sample sites throughout wa. rainfall is a major environmental ... | 2011 | 21255449 |
| arboviruses of human health significance in papua new guinea. | arboviruses (arthropod-borne viruses) are important emerging pathogens in many tropical and developing countries of the world. the southeast asian and western pacific regions have recently experienced large outbreaks of dengue, japanese encephalitis and chikungunya fever. in papua new guinea (png) serological surveys and mosquito isolation experiments suggest that arboviruses are prevalent throughout the country. however, the lack of surveillance and clinical reporting means that the distributio ... | 2014 | 25338473 |
