Human mobility and COVID-19 in suburban cities
19 Oct 2022
Osaka Metropolitan University researchers conducted a study of human mobility to find effective lifestyle changes that enable people to exist with the novel coronavirus COVID-19, while maintaining social and economic activities. They found that restricting the human mobility in specific areas according to the state of the pandemic, rather than uniformly controlling human mobility, could be effective in reducing the number of new COVID-19 infections.

Researchers from Osaka University have found that the Vibrio cholerae colonization factor TcpF forms a flower-shaped trimer to specifically bind to the minor pilus protein TcpB resulting in secretion by the type 4 pilus secretion system into the extracellular space. This finding could help lead to the development of a novel anti-adhesive drug that selectively interrupts the TcpF-TcpB interaction, which may replace antibiotics in the treatment of cholera.

Low concentrations of cetylpyridinium chloride, an antimicrobial agent present in mouthwashes, inhibit the infectivity of four variants of SARS-CoV-2.

While the primary site of SARS-CoV-2 infection is in the nose, most antiviral immunity studies have been performed with peripheral blood. T-cell analysis of nasal swab samples suggests getting infected with SARS-CoV-2 following vaccination could confer potentially more robust, nasal-based immunity.

Mr Heng Swee Keat speaks at the launch of the Duke-NUS Centre for Outbreak Preparedness
11 Jun 2022
Duke-NUS is working with the Bill and Melinda Gates Foundation to develop the Asia Pathogen Genomics Initiative (APGI) to improve regional genomic surveillance and sequencing capacity. New Centre for Outbreak Preparedness will support APGI and work closely with national and global partners to enhance regional capacity to predict, prepare and respond to future health threats.

Mycobacterial extracellular infection of red blood cells
29 Mar 2022
Mycobacteria are a group of pathogenic bacteria that cause diseases like leprosy and tuberculosis in humans. Now, a new study by scientists at Hiroshima University finds that mycobacteria are associated with red blood cells at lung infection sites, an interaction that has escaped scientific notice for 140 years since the discovery of the organism causing tuberculosis.

Researchers at the Department of Microbiology at The University of Hong Kong have succeeded in the isolation of SARS-CoV-2 Omicron variant from clinical specimens. This is the first known research team in Asia that has succeeded in isolating the Omicron variant. The isolated variant will enable the development and production of vaccines against Omicron, which has been designated as a "variant of concern" by the World Health Organization.

Scientists are turning to genomics to better understand the epidemiology of malaria and to inform control and elimination interventions and strategies. In the Lake Victoria region of Kenya, malaria burden remains very high despite more than a decade of intense control activities. A team of researchers from Osaka City University, Nagasaki University, London School of Hygiene and Tropical Medicine, and Mount Kenya University generated whole Plasmodium falciparum genome sequences from the lake region. Their analyses revealed that malaria parasites from this region appear distinct from other parasites from East Africa, while frequencies of known drug resistance markers were similar to those in other East African parasite populations. Their findings will help to develop improved surveillance tools to determine parasite transmission routes and aid clinical disease management.
