Rapid Assay Monitors Influenza Virus Susceptibility

Early detection of drug-resistant influenza viruses is needed for timely modification of policies and recommendations on the use of antivirals. In many countries, neuraminidase (NA) inhibitor(s) are the medications of choice for treatment and prophylaxis of influenza infections, with oseltamivir being most commonly prescribed. More...

Image: The low-cost manual “paperfuge” was inspired by the whirligig toy, in which a loop of twine is thread through two holes in a button or disk. The loop ends are grabbed then rhythmically pulled. As the twine coils and uncoils, the button spins at a high speed. Bioengineers designed the paperfuge to concentrate parasites like malaria in blood (Photo courtesy of Stanford University).

Manually Powered Device Separates Blood for Diagnosis

Inspired by a whirligig toy, researchers have used its mechanical principles to develop an ultra-low-cost, hand-powered blood centrifuge out of paper, no electricity required. The tool could improve diagnosis of diseases like malaria, African sleeping sickness, and tuberculosis in resource-poor, off-the-grid regions where these diseases are prevalent. More...

Research Makes Flu Virus Visible to Naked Eye

Researchers have discovered a way to make influenza visible to the naked eye by engineering fluorescent dye molecules to target a specific enzyme of the virus. The team was able to develop a prototype test kit that detects influenza in samples using a handheld lamp or blue laser pointer, and that even helps determine if a given antiviral therapy will likely be effective.

Typhoid Fever Victims Present Unique Metabolomic Profile

A panel of metabolic markers distinguishes patients with typhoid fever from others suffering from non-typhoid tropical fevers such as malaria. More...

Immune Response Differentiates Malaria from Other Infections

Malaria affects around 200 million people around the world but its non-specific symptoms, coupled with a lack of access to testing facilities, mean it is difficult to distinguish from other infectious diseases. More...

Drug-Resistant Bacteria Can Raise Sepsis Risk

Sepsis affects an estimated 30 million people worldwide each year and without quick treatment, it can lead to multiple organ failure and death. Treating sepsis can be even more difficult if the bacteria responsible are resistant to antibiotics. More...

POC Test Advances Hepatitis C Diagnosis

A new test that enables diagnosis of hepatitis C infection in a single visit could improve access to early diagnosis, monitoring, and treatment service for some of the most vulnerable people in Australia and the world. More...
