Electronic nose ‘sniffs faeces to detect infection’

BBC News James Gallagher 1 September 2014

Sniffing faeces with an “electronic nose” can detect strains of bacteria that can cause deadly infections, say UK researchers.  The tool was able to sniff out different types of Clostridium difficile based on the stinky chemicals they released.

The team at the University of Leicester say the findings could be useful for screening patients in hospital.  The study was published in the journal Metabolomics.

You have a bacterial ‘aura’ that follows you around

ScienceAlert Australia Felicity Nelson 30 August 2014

Scientists have found a microbial ‘aura’ of unique and identifiable communities of bacteria living on people’s skin and in their homes. These communities follow people whereever they go and leave traces that can be used almost like a fingerprint to determine a person’s movements.  Forensic scientists can use this microbial ‘fingerprint’ to trace your movements.

Queensland government hands out $25m in HIV and STI funding

Brisbane Times Cameron Atfield 31 August 2014

The Queensland government will provide $25.1 million over three years to help community groups combat HIV, sexually transmitted diseases and other blood-borne viruses.

Health Minister Lawrence Springborg said the funding, spread over four grants, was awarded after 15 applicants from community-based agencies were assessed.

Common gut bacteria could treat food allergies

ScienceAlert Fiona MacDonald 27 August 2014

New research from the University of Chicago in the US shows that a class of bacteria known as Clostridia can block peanut allergies in mice, and suggests it could be used to treat similar conditions in humans.
Clostridia is one of the types of bacteria killed off by antibiotic use in early childhood, and this research supports the emerging theory that increased antibiotic use is one of the factors that has caused food allergies in kids to rise by 50% since 1997.

Researchers discover why Listeria bacterium is so hard to fight

EurekAlert 27-Aug-2014

Listeria is a dreaded bacterium that can be found in both unprocessed and processed foods. Over the last few weeks, 28 persons in Denmark have been infected with Listeria from processed food, sold in supermarkets. 13 have died.
The bacterium is notoriously difficult to fight because it has an almost uncanny ability to adapt to changes in its surroundings, says Associate Professor Birgitte Kallipolitis, University of Southern Denmark. Together with colleagues from the Department of Biochemistry and Molecular Biology, she has published a study, which in details reveals how this extreme ability to adapt takes place.
The researchers tested how Listeria reacts when it is exposed to a number of substances that can normally fight pathogenic bacteria. In the laboratory, Listeria was exposed to antibiotics, bile, salt, acid and ethanol, similar to what it often encounters in food, in the human body and during disinfection.

Researchers identify tests to diagnose invasive aspergillosis with 100 percent accuracy

(Elsevier Health Sciences 13 August 2014) The fungal infection invasive aspergillosis can be life threatening, especially in patients whose immune systems are weakened by chemotherapy or immunosuppressive drugs. Despite the critical need for early detection, IA remains difficult to diagnose. A study in The Journal of Molecular Diagnostics compared three diagnostic tests and found that the combination of nucleic acid sequence-based amplification and real-time quantitative polymerase chain reaction detects aspergillosis with 100% accuracy.
