First Smartphone DNA Test for Chlamydia to Be Presented at 2015 AACC Annual Meeting

PR Newswire July 29, 2015

At the 2015 AACC Annual Meeting & Clinical Lab Expo, researchers will present findings that a first-of-its-kind smartphone test for chlamydia can detect the disease with high accuracy, which could reduce the prevalence of this sexually transmitted disease (STD) by making chlamydia screening easier and cheaper.
Most people with chlamydia are not aware of it because the infection often causes no symptoms, but if left untreated, this STD can develop into pelvic inflammatory disease and irreversibly damage a woman’s reproductive system. According to the Centers for Disease Control and Prevention, pelvic inflammatory disease affects up to 30% of women with chlamydia, and can cause infertility; debilitating, chronic pelvic pain; and life-threatening ectopic pregnancies. Over the past decade, healthcare providers have been able to expand screening programs for chlamydia thanks to the development of a highly sensitive method known as nucleic acid amplification testing (NAAT). NAATs are too complex, however, to perform in point-of-care settings such as physicians’ offices, health fairs, school clinics, or other sexual health outreach venues, and they also have a high per-test cost.

Diabetics at greater risk of TB: study

Brisbane Times AAP 27 July 2015

A 20-year James Cook University study has found the weakened immune systems of diabetics make them more vulnerable to tuberculosis.

“If you suffer from diabetes and your immune system is not functioning well, it can flare up,” Director of Microbiology at Townsville Hospital, Dr Robert Norton, said.

All diabetes sufferers should therefore be screened for tuberculosis, he said.

Super sugar: Hope for new antibiotics as researchers develop compound to fight superbug bacteria

ABC News 22 July 2015

A team of Queensland scientists has found a way to fight superbugs using the bacteria’s own sugar.

University of Queensland scientists said new antibiotics that were unlikely to develop resistance were urgently needed to combat the rise of superbugs — drug-resistant bacteria.

The new compound acts as a Trojan horse, disguising itself as a bacteria’s own sugar, before stopping the bacteria from the inside.

Professor Matt Cooper from the University of Queensland said the compound was not sucrose, but instead a unique type of sugar.
