Infected mozzies put bite on dengue

Townsville Bulletin SAMANTHA HEALY  October 30, 2014

WELCOME to Ground Zero — a leafy suburban backyard in South Townsville where the fight to eliminate dengue fever will start today.
Eliminate Dengue researchers will place the first container of lab-harvested Wolbachia-infected Aedese aegypti mosquito eggs at this Hubert St house this morning, as part of their city wide trials aimed at eradicating the potentially lethal disease.
Two teams will place containers at about 40 South Townsville properties by the end of the day.
When the eggs hatch, they will release mosquitoes carrying the naturally-occurring Wolbachia bacteria, which prevents the transmission of dengue.
It is hoped the Wolbachia mosquito will breed with wild mosquitoes, and effectively vaccinate the local mosquito population against dengue.

Ebola is not the only, or most dangerous, challenge we face

ON LINE Opinion Peter Curson 28 October 2014

Each day we are confronted by disturbing stories of how Ebola continues to wreck havoc in West Africa and by the threat that it offers to the rest of the world.  In Australia considerable concern has been expressed about the possibility of a returning healthcare worker or tourist transporting the infection to our shores.

But what about the major epidemic of mosquito-borne infectious disease that has been raging through the Pacific Islands over the last two years.

Global infection outbreaks, unique diseases rising since 1980

(Brown University 28 October 2014) Ebola has a lot of company. In a novel database now made publicly available, Brown University researchers found that since 1980 the world has seen an increasing number of infectious disease outbreaks from an increasing number of sources. The good news, however, is that they are affecting a shrinking proportion of the world population.

Skin patch could replace the syringe for disease diagnosis

EurekAlert 22 October 2014

Drawing blood and testing it is standard practice for many medical diagnostics. As a less painful alternative, scientists are developing skin patches that could one day replace the syringe. In the ACS journal Analytical Chemistry, one team reports they have designed and successfully tested, for the first time, a small skin patch that detected malaria proteins in live mice. It could someday be adapted for use in humans to diagnose other diseases, too.

In-depth analysis of bat influenza viruses concludes they pose low risk to humans

(PLOS 2 October 2014) Zoonosis — transmission of infections from other vertebrates to humans — causes regular and sometimes serious disease outbreaks. Bats are a well-known vertebrate reservoir of viruses like rabies and Ebola. Recent discovery of sequences in bats that are resemble influenza virus genes raised the question of whether bat flu viruses exist and could pose a threat to humans. A study published on Oct. 2 in PLOS Pathogens addresses this question based on detailed molecular and virological characterization.

NIH study supports camels as primary source of MERS-CoV transmission

(NIH/National Institute of Allergy and Infectious Diseases 24 September 2014) NIH and Colorado State University scientists have provided experimental evidence supporting dromedary camels as the primary reservoir, or carrier, of Middle East respiratory syndrome coronavirus. The study, designed by scientists from CSU and NIH’s National Institute of Allergy and Infectious Diseases, involved three healthy camels exposed through the eyes, nose and throat to MERS-CoV isolated from a patient. Each camel developed a mild upper respiratory tract infection consistent with what scientists have observed throughout the Middle East.

Anti-malarial drug could reverse cancer growth, researchers say

ABC News 12 September, 2014

Researchers have found that common anti-malaria drugs were able to reverse the growth of cancerous cells during tests on fruit flies.
Experts from the Peter MacCallum Cancer Centre in Melbourne said during the trial they discovered a mutation very similar to one that a malarial parasite needs to thrive.
