What’s in your landscape? Plants can alter West Nile virus risk

EurekAlert 1 July 2015

A new study looks at how leaf litter in water influences the abundance of Culex pipiens mosquitoes, which can transmit West Nile virus to humans, domestic animals, birds and other wildlife.

The study found that different species of leaf litter in standing water influence where Culex pipiens mosquitoes deposit their eggs, how quickly the larvae grow, how big they get and whether they survive to adulthood. Because the mosquitoes feed on bacteria that grow on leaf litter, the team also measured how native and non-native leaf species influenced bacterial abundance and diversity.

The study is reported in the journal Parasites and Vectors.

Vanderbilt research could lead to vaccines and treatment for dengue virus

EurekAlert 2 July 2015

Researchers at Vanderbilt University and the National University of Singapore have determined the structure of a human monoclonal antibody which, in an animal model, strongly neutralizes a type of the potentially lethal dengue virus.

The finding, reported today July 2 in the journal Science, could lead to the first effective therapies and vaccines against dengue, a complex of four distinct but related mosquito-borne viruses that infect about 390 million people a year and which are a leading cause of illness and death in the tropics.

Lyme disease: Tick researcher finds bacteria with similar symptoms to controversial disease

ABC News 30 June 2015

Bacteria found in Australian ticks can cause similar symptoms to Lyme disease, but research is no closer to proving tick bites cause the controversial illness domestically, a researcher says.

Perth-based Murdoch University Professor Peter Irwin is heading up a national research team that has collected up to 20,000 ticks from across the country to study the bacteria they carry and their potential to cause disease.

The study is being conducted by researchers from both Murdoch and Curtin universities as well as the University of Sydney.

New anti-malaria drug developed at Dundee University

BBC News 17 June 2015

Researchers at Dundee University have discovered a new compound which could treat malaria while protecting people from the disease and preventing its spread, all in a single dose.
The compound, DDD107498, was developed by the university’s Drug Discovery Unit and the Medicines for Malaria Venture.
Scientists said the “exciting” new drug could work well against parasites resistant to current treatments.
Details of the discovery have been published in the journal Nature.

Chikungunya virus surrounds Australia: Outbreak ‘a matter of time’

news.com.au 17 June 2015

ONE by one the dominoes have fallen: India. Indonesia. Fiji. Australia is surrounded. It’s just a matter of time before a new and crippling virus establishes a bridgehead on our shores.

And it’s not just an annoyance, like the flu.

Outbreaks have severe social and economic implications.

What happened at Reunion Island, a French outpost in the middle of the Indian Ocean, during the early stages of the virus’ march is a case in point: A third of the population — 250,000 people — were infected, bringing whole industries to a virtual standstill for months. Eventually it took 500 soldiers to drive the mosquitoes — and the disease they carried — back into the ocean.

In December 2013, the disease was first noticed in the Carribbean: Since then more than 1.3 million people have caught the disease.

“It could establish itself in Australia,” Dr Senanayake says. “But it hasn’t done so yet — thankfully. It’s something we have to watch out for.
