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.

Ebola risk on Gold Coast ‘extremely small’ September 11, 2014

THE likelihood that a man taken to hospital with Ebola-like symptoms actually has the killer illness is “extremely small”, an expert who’s assessed him says.
THE sick 27-year-old man was taken from the Southport watch house to Gold Coast University Hospital on Thursday morning by paramedics wearing full protective gear.
They treated the case seriously after the man complained of fever, one of the main symptoms of Ebola, and revealed he’d only just returned from the Congo in Africa.
The man had spent four hours at the watch house after being arrested for trespassing at Surfers Paradise, but did not tell police he was sick when he was arrested. A police spokesman said there was no need to close the watch house. Gold Coast University Hospital’s director of infectious diseases John Gerrard said initial assessment of the patient suggested it was extremely unlikely the man had the killer disease.
“We are managing him in accordance with the standard national protocols for isolation of patients who are potentially at risk of Ebola disease,” Dr Gerrard told reporters. “I must emphasise the risk of this patient having Ebola virus disease is extremely small.” Test results are expected by Thursday evening.

Suspected Ebola patient on Gold Coast

Brisbane Times September 11, 2014

A man feared to have contracted the potentially deadly Ebola virus in Africa has been taken to the Gold Coast University Hospital.
The 25-year-old contacted paramedics at 7.40am on Thursday complaining of feeling unwell, a Queensland Ambulance spokeswoman told Fairfax Media.
The man, from Southport on the Gold Coast, returned from the Congo two days ago and has been seriously ill since, the Gold Coast Bulletin reported.
Gold Coast Health acting chief executive Damian Green said in a statement on Thursday morning: “Gold Coast Health can confirm a patient has been transferred to Gold Coast University Hospital after being identified by paramedics as having symptoms of Ebola virus.
“Gold Coast Health is taking necessary precautions and has isolated the patient who is currently being assessed.
“Gold Coast Heath has processes in place to safely manage such circumstances.

Use of dengue vaccine may cause short-term spikes in its prevalence

(Oregon State University 4 September 2014) As researchers continue to work toward vaccines for serious tropical diseases such as dengue fever, experts caution in a new report that such vaccines will probably cause temporary but significant spikes in the disease in the years after they are first used.

New discovery could help turn antibiotic into antimalarial drug

EurekAlert 2-Sep-2014

Melbourne researchers are making progress towards new antimalarial drugs, after revealing how an antibiotic called emetine blocks the molecular machinery that produces the proteins required for malaria parasite survival.
Although emetine is effective against malaria it is not used as a preventive drug due to its significant side effects. However, the work of Walter and Eliza Hall Institute researchers Dr Wilson Wong, Dr Jake Baum and colleagues in showing how emetine attaches to and blocks the molecular machinery that makes the proteins required for malaria parasite survival has revealed new approaches for antimalarial drug development.
