Mosquito-borne virus may lead to severe brain infection

(American Academy of Neurology 25 November 2015) The mosquito-borne virus chikungunya may lead to severe brain infection and even death in infants and people over 65, according to a new study that reviewed a chikungunya outbreak on Reunion Island off the coast of Madagascar in 2005-2006. The study is published in the Nov. 25, 2015, online issue of Neurology, the medical journal of the American Academy of Neurology.

University of California scientists create malaria-blocking mosquitoes

(University of California – Irvine 23 November 2015) Using a groundbreaking gene editing technique, University of California scientists have created a strain of mosquitoes capable of rapidly introducing malaria-blocking genes into a mosquito population through its progeny, ultimately eliminating the insects’ ability to transmit the disease to humans. This new model represents a notable advance in the effort to establish an antimalarial mosquito population, which with further development could help eradicate a disease that sickens millions worldwide each year.

Researchers discover ‘good’ mosquito virus that could eradicate diseases

ABC News | ABC Far North Mark Rigby, Phil Staley 18 November 2015

Scientists have discovered a virus carried by mosquitoes that could pave the way to eradicating mosquito-borne diseases such as Ross River virus, and potentially dengue fever.

The virus, known as Parramatta River virus, was discovered in a joint research project by scientists at the University of Queensland (UQ) and the University of Sydney.

USC Grand Challenges Explorations winner

Sunshine Coast Daily 13 November 2015

THE University of the Sunshine Coast has been announced as a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation.  Principal investigator Dr Joanne Macdonald, a Senior Lecturer and researcher in molecular engineering, will pursue an innovative global health and development research project, titled ‘A rapid field test for detecting infected mosquitoes’.

The project will also draw on the expertise of key collaborators, including entomologists Dr Andrew van den Hurk (Queensland Health Forensic and Scientific Services in Brisbane) and Dr Leon Hugo (QIMR Berghofer Medical Research Institute in Brisbane); and virologists Dr Cheryl Johansen (University of Western Australia in Perth) and Professor Roy Hall (University of Queensland in Brisbane).

Queensland scientists discover quick dengue test

Brisbane Times 13 November 2015

A pair of Queensland scientists are one step closer to creating a world-first hand-held device able to detect dengue fever in wild mosquitoes.

University of Queensland professors Matt Cooper and Paul Young say their portable device would give people a better chance to safeguard against breakouts of the potentially-fatal tropical virus.

Currently, mosquitoes are caught and tested for dengue, but samples must be sent to a lab for confirmation.

Their device would instead provide an immediate result at a fraction of the cost.

Research points to development of single vaccine for Chikungunya, related viruses

(Washington University School of Medicine 10 November 2015) What if a single vaccine could protect people from infection by many different viruses? That concept is a step closer to reality. Researchers at Washington University School of Medicine in St. Louishave identified ‘broadly neutralizing’ antibodies that protect against infection by multiple, distantly related alphaviruses — including Chikungunya virus — that cause fever and debilitating joint pain. The discovery, in mice, lays the groundwork for a single vaccine or antibody-based treatment against many different alphaviruses.
