Unravelling Plasmodium Vivax Transmission To Anopheles Mosquitoes: Role Of Naturally Acquired Transmission Blocking Immunity And Efficacy Of Novel Vaccine And Drug Candidates

Summary
This project is aimed at better understanding transmission of P. vivax, the world’s most widely spread malaria parasite. Using a newly established experimental platform that enables us to feed P. vivax infected blood to Anopheles farauti mosquitoes, we can start researching factors in human blood that determine P. vivax infection success, test new vaccine and drug candidates for their ability to block transmission and thus significantly advance science surrounding this neglected parasite.
Dynamics Of Malaria Transmission Stages In Host And Vector: Bottlenecks And Their Impact Transmission And Parasite Population Diversity

Summary
The adoption of malaria elimination as the long-term goal requires malaria programs to shift their focus from controlling the burden of malaria disease & deaths to the interruption of transmission itself. This will be impossible without an improved understanding of the processes involved and novel tools directly targeting transmission. We therefore plan to conduct an in-depth examination of bottlenecks to malaria transmission in Papua New Guinea, the country with the highest malaria burden in ou ....The adoption of malaria elimination as the long-term goal requires malaria programs to shift their focus from controlling the burden of malaria disease & deaths to the interruption of transmission itself. This will be impossible without an improved understanding of the processes involved and novel tools directly targeting transmission. We therefore plan to conduct an in-depth examination of bottlenecks to malaria transmission in Papua New Guinea, the country with the highest malaria burden in our region.Read moreRead less
Elimination Of Zoonotic Schistosomiasis And Echinococcosis Through Integrated Morbidity Control

Funding Amount
$898,008.00
Summary
I am a parasitologist researching the biology, immunology and epidemiology of human parasitic worms, particularly the schistosome bloodflukes and the hydatid tapeworms, which cause bilharzia and hydatidosis, diseases of the world’s poorest people that cause both major suffering and economic loss. My goal is to develop new methods, including vaccination, to control and eventually eliminate these parasites.

Summary
Cysticercosis and hydatid disease are caused by infections with the larval stages of tapeworm parasites. These infections cause substantial morbidity and mortality throughout the world, but particularly in developing countries. They are zoonotic diseases, being transmitted to humans from animals. This project aims to develop practical vaccines to assist with the prevention of both cysticercosis and hydatid disease in humans.

These infections cause substantial morbidity and mortality throughout the world, but particularly in developing countries. They are zoonotic diseases, being transmitted to humans from animals. This project aims to develop practical vaccines to assist with the prevention of both cysticercosis and hydatid disease in humans. The vaccines will be used in the parasites' natural animal hosts, thereby breaking the parasite life-cycle and preventing the diseases being passed to humans. Substantial preliminary research has been undertaken by the applicant, including completion of successful preliminary vaccine trials. This project will optimise the vaccines and complete initial field trials in countries with high rates of disease transmission.Read moreRead less
Impact Of The Three Gorges Dam On Transmission And Future Control Of Human Schistosomiasis In China

Summary
A million Chinese have schistosomiasis or snail fever. When the Three Gorges Dam on the Yangtze River is fully operational, considerable environmental-ecological changes will result, increasing spread of this parasitic disease. In a unique study we will assess the impact of the Dam on schistosomiasis, and test and model a series of options for its control. The findings will be important for China and other areas where schistosomiasis occurs and where similar dams are planned or are under way.

Summary
Professor Lightowlers’ has developed the world’s most effective vaccines against diseases caused by parasites. The vaccines prevent transmission of parasites from livestock animals to humans. During the next 5 years the vaccines will be produced on a large scale and evaluated in field trials. The products of this research program will make a major contribution to reducing the number of people suffering from parasitic cysts.
Helminth Secretomes: From Vaccines To Novel Anti-inflammatory Biologics

Funding Amount
$938,910.00
Summary
Billions of people in developing countries are infected with parasitic worms, but they have been eradicated from industrialised nations. Humans co-evolved with worms, so their recent removal has deprived us of signals required to keep inflammation in check. My research focuses on worm molecules that can be used to (1) develop vaccines to combat these parasitic infections in developing countries, and (2) as a novel platform of anti-inflammatory therapeutics for use in industrialised nations.
Unravelling The Tetraspanin Web In The Schistosome Tegument.

Funding Amount

Summary
Infection with the human blood fluke, Schistosoma mansoni, is a major human ailment affecting almost 200 million people world wide and causing approximately 200 000 deaths per year. Current control efforts rely on anthelminthic drugs but, to sustain their effects, they must be applied for an indefinite period of time due to reinfection. This project will extend recent efforts to develop a vaccine for this organism and decrease the public health burden and mortality associated with infection.

Summary
About 2 million people die each year from complications of malaria infection. A frequent, life-threatening complication of severe malaria is lung oedema. There is no specific treatment for the lung complications, which are poorly understood. There has been until now no good model system to study malaria lung complications. We have developed in mice an experimental model of malaria specifically to determine the mechanisms that cause lung pathology, which has never been done before.

There is no specific treatment for the lung complications, which are poorly understood. There has been until now no good model system to study malaria lung complications. We have developed in mice an experimental model of malaria specifically to determine the mechanisms that cause lung pathology, which has never been done before. Such experiments cannot be performed in humans for ethical and logistical reasons. We believe that pulmonary oedema is caused by products of the immune system and we will rigorously test this idea in our study. The aim is to learn more about the processes occurring in this disease so as to devise new treatment strategies.Read moreRead less
