isolation of hendra virus from pteropid bats: a natural reservoir of hendra virus.since it was first described in australia in 1994, hendra virus (hev) has caused two outbreaks of fatal disease in horses and humans, and an isolated fatal horse case. our preliminary studies revealed a high prevalence of neutralizing antibodies to hev in bats of the genus pteropus:, but it was unclear whether this was due to infection with hev or a related virus. we developed the hypothesis that hev excretion from bats might be related to the birthing process and we targeted the reproductive tr ...200010900029
hendra virus infection dynamics in the grey-headed flying fox (pteropus poliocephalus) at the southern-most extent of its range: further evidence this species does not readily transmit the virus to horses.hendra virus (hev) is an important emergent virus in australia known to infect horses and humans in certain regions of the east coast. whilst pteropid bats ("flying foxes") are considered the natural reservoir of hev, which of the four mainland species is the principal reservoir has been a source of ongoing debate, particularly as shared roosting is common. to help resolve this, we sampled a colony consisting of just one of these species, the grey-headed flying fox, (pteropus poliocephalus), at ...201627304985
measuring physiological stress in australian flying-fox populations.flying-foxes (pteropid bats) are the natural host of hendra virus, a recently emerged zoonotic virus responsible for mortality or morbidity in horses and humans in australia since 1994. previous studies have suggested physiological and ecological risk factors for infection in flying-foxes, including physiological stress. however, little work has been done measuring and interpreting stress hormones in flying-foxes. over a 12-month period, we collected pooled urine samples from underneath roosting ...201424990534
hendra in the hunter june 2019 the first equine case of hendra virus in the hunter valley, new south wales, australia was detected. an urgent human and animal health response took place, involving biosecurity measures, contact tracing, promotion of equine vaccinations and investigation of flying fox activity in the area. no human or additional animal cases occurred. equine vaccination uptake increased by over 30-fold in the surrounding region in the three months following the case. black flying fox and grey-heade ...202033117876
environmental drivers of spatiotemporal foraging intensity in fruit bats and implications for hendra virus the australian subtropics, flying-foxes (family pteropididae) play a fundamental ecological role as forest pollinators. flying-foxes are also reservoirs of the fatal zoonosis, hendra virus. understanding flying fox foraging ecology, particularly in agricultural areas during winter, is critical to determine their role in transmitting hendra virus to horses and humans. we developed a spatiotemporal model of flying-fox foraging intensity based on foraging patterns of 37 grey-headed flying-foxes ...201829934514
seroprevalence of three paramyxoviruses; hendra virus, tioman virus, cedar virus and a rhabdovirus, australian bat lyssavirus, in a range expanding fruit bat, the grey-headed flying fox (pteropus poliocephalus).habitat-mediated global change is driving shifts in species' distributions which can alter the spatial risks associated with emerging zoonotic pathogens. many emerging infectious pathogens are transmitted by highly mobile species, including bats, which can act as spill-over hosts for pathogenic viruses. over three years, we investigated the seroepidemiology of paramyxoviruses and australian bat lyssavirus in a range-expanding fruit bat, the grey-headed flying fox (pteropus poliocephalus), in a n ...202032374743
spatiotemporal aspects of hendra virus infection in pteropid bats (flying-foxes) in eastern australia.hendra virus (hev) causes highly lethal disease in horses and humans in the eastern australian states of queensland (qld) and new south wales (nsw), with multiple equine cases now reported on an annual basis. infection and excretion dynamics in pteropid bats (flying-foxes), the recognised natural reservoir, are incompletely understood. we sought to identify key spatial and temporal factors associated with excretion in flying-foxes over a 2300 km latitudinal gradient from northern qld to southern ...201526625128
experimental hendra virus infectionin pregnant guinea-pigs and fruit bats (pteropus poliocephalus).antibodies to hendra virus (hev) have been found in a high percentage of fruit bats (pteropus spp.) in australia, indicating a possible reservoir for the virus. the aim of the experiments reported here was to investigate transplacental infection as a possible mode of transmission of the virus in fruit bats and other animals. in a first experiment, 18 pregnant guinea-pigs in the mid-stage of gestation were inoculated with hev, as an experimental model in a conventional laboratory animal. nine dev ...200010684689
[zoonoses caused by new viruses in the paramyxoviridae family].based on the literature data, the outbreaks of new zoonoses caused by new members of the family paramyxoviridae are briefly presented. some characteristics of hendra and nipah virus, epidemiological aspects, clinical picture and pathology are described. fruit bats are mentioned as the key to the epidemiology of hendra virus. the virus was isolated from affected humans, horses, and from the uterine fluids of a grey-headed fruit bat (pteropus poliocephalus). new morbillivirus designated nipah viru ...200111554115
