A one health approach to establish surveillance strategies for Japanese encephalitis and zoonotic arboviruses in Papua New Guinea

Indicative Funding
$23,700 (administered by CSIRO)
Summary
The project aim is to establish surveillance for JEV and other zoonotic arboviruses that affect the rural population of PNG. The major objectives are to: 1. Evaluate current detection methods to detect zoonotic arboviruses in the field and laboratory, and build capacity where gaps are identified. 2. Establish surveillance at selected sites using sentinel animal (pigs, chickens) and mosquito trapping 3. Develop linkages and coordination between human and animal health agencies. The primary outputs are to develop surveillance activities that contribute to early warning for public health and provide a better understanding of the ecological drivers of arboviruses in PNG.

Application for Next Generation Sequencing of mosquito excreta to identify arboviruses, microorganisms and mosquito species

Indicative Funding
$35,000 (administered by Menzies School of Health Research)
Summary
Traditional testing for arboviruses in mosquitoes requires a priori knowledge and choosing appropriate assays for their detection. Mosquitoes can potentially provide a lot of additional information, including other unexpected or unknown arboviruses, and their own genetic material. Moreover, mosquitoes in effect act as environmental samplers (?flying syringes?), taking blood from the humans and animals they feed upon. These blood samples could potentially be infected with other pathogens that are not necessarily mosquito-transmitted. Next generation sequencing is a rapidly advancing technology that allows us to obtain all this information from a sample without any prior knowledge of virus, host or vector. We are proposing to use next generation sequencing of mosquito excreta to identify pathogens in mosquitoes collected from locations where different vertebrate groups inhabit, including urban areas, bat colonies, domesticated animals, marsupials, reptiles and avian hosts.

Can mosquito excreta be used to enhance detection of Australian vector-borne diseases?

Indicative Funding
$31,000 (administered by Menzies School of Health Research)
Summary
Testing for presence of arboviruses usually involves capturing wild mosquitoes and complicated laboratory analyses. These are not only time- and labour-intensive but also costly. Virus detection can be made from saliva however, mosquitoes only expel very small amounts which makes detection difficult. We are proposing to use their excreta instead as it is produced in greater quantities than saliva, and shows higher sensitivity in virus detection. In order to explore this proposal we need to know where and when mosquitoes discharge their excreta in the traps. The discharge of excreta could be dependent on a variety of factors such as temperature, time after last meal or time of day/night, type of trap; it may also be species-dependent or it could just be random. These factors need to be examined to ensure maximum collection of excreta. The results will lead to the modification and optimization of existing traps.
