Back in 2013 I built a Wall of Polio in my laboratory – a large stack of six-well cell culture plates that have been used to measure the concentration of polioviruses in various samples by plaque assay. It became a focal point of the lab at which many guests came to have their photographs taken.... Read More
A group of collaborators led by the University of Southampton have been awarded a British Council Newton Fund Institutional Links Grant to support ground-breaking research towards reducing the burden of infectious disease in Malaysia. Read More
Washington, DC – August 20, 2015 - Swedish exchange students who studied in India and in central Africa returned from their sojourns with an increased diversity of antibiotic resistance genes in their gut microbiomes. The research is published 10 August in Antimicrobial Agents and Chemotherapy, ... Read More
HIV-infected patients remain on antiretroviral therapy for life because the virus survives over the long-term in infected dormant cells. Interruption of current types of antiretroviral therapy results in a rebound of the virus and clinical progression to AIDS. Read More
An Ebolavirus vaccine has shown promising results in a clinical trial in Guinea. This vaccine has been in development since 2004 and was made possible by advances in basic virology of the past 40 years. Read More
