Researchers develop world’s most sensitive test to detect infectious disease, superbugs

(McMaster University 6 July 2015) Infectious diseases such as hepatitis C and some of the world’s deadliest superbugs — C. difficile and MRSA among them — could soon be detected much earlier by a unique diagnostic test, designed to easily and quickly identify dangerous pathogens.

Study: Whooping cough resurgence due to vaccinated people not knowing they’re infectious?

(Santa Fe Institute 24 June 2015) The dramatic resurgence of whooping cough is due, in large part, to vaccinated people who are infectious but who do not display the symptoms, suggests a new study by two Santa Fe Institute researchers in BMC Medicine.

Investigation into deadly ‘bath milk’

Sydney Morning Herald AAP 3 July 2015

A working group will investigate ways to stop the consumption of raw milk being marketed as bath milk.

A meeting of Australian and New Zealand government ministers on Friday said the working group would consider options for a national approach to preventing the consumption of the cosmetic product, which can cause severe illness and death if consumed.

It comes after raw milk marketed as bath milk was linked to one child death and four cases of serious illness in Victoria last year.

Superbugs, antibiotic resistance and the Queensland team fighting back

Brisbane Times 2 July 2015

South-east Queensland is leading the fight to protect our final defense against deadly superbugs.

The Australian government launched the country’s first strategy to address antimicrobial resistance (AMR) last month, labelling it an “urgent global health priority”.

The strategy set out plans to raise awareness of AMR, co-ordinate research to attack the problem and cut down on the overuse of antibiotics in both humans and animals, where the drugs are commonly used as a preventative measure or to stimulate growth.

Researchers from the University of Queensland, Queensland University of Technology and Bond University were tasked with finding a way to cut down on GP prescriptions and educate the public.

Research matters

EurekAlert 25 June 2015

A new PLOS Pathogens forum explains how basic research is necessary, exciting, and makes a difference.

“We seek this new Research Matters format for individual scientists to tell the public how diverse fundamental research into pathogens assures real and compelling impact on public health, human knowledge and life”, state Kasturi Haldar and Grant McFadden, the journal’s Editors-in-Chief in their introductory editorial, which, alongside the first two first contributions to the new series, will be published on June 25th in PLOS Pathogens.

How small genetic change in Yersinia pestis changed human history

EurekAlert 30 June 2015

While studying Yersinia pestis, the bacteria responsible for epidemics of plague such as the Black Death, Wyndham Lathem, Ph.D., assistant professor in microbiology-immunology at Northwestern University Feinberg School of Medicine, found a single small genetic change that fundamentally influenced the evolution of the deadly pathogen, and thus the course of human history.

In a paper published in Nature Communications, Lathem and first author Daniel Zimbler, Ph.D., a Feinberg post-doctoral fellow, demonstrated how the acquisition of a single gene caused the shift of Y. pestis from causing a primarily gastrointestinal infection to a more serious and often fatal respiratory disease. They further showed how later modifications of this gene enhanced infections associated with the bubonic plague.
