Scientists at the Forsyth have gained new insight on how Tuberculosis (TB) remains a global epidemic. Although drugs have been available to fight TB for 50 years, the disease still infects nearly 2.2 billion people worldwide and causes 1.7 million annual deaths. This is largely attributed to the bacteria's ability to stay dormant in the human body and later resurface as active disease. The Forsyth team, and its collaborators from Stanford University, has recently discovered that Mycobacterium tuberculosis, the bacteria that causes TB, can lay dormant and thrive within bone marrow stem cells. http://medicalxpress.com/news/2013-01-scientists-gain-latent-tuberculosis.html Diseases, Conditions, Syndromes Wed, 30 Jan 2013 14:00:01 EST news278766332 The presence of a certain molecule allows the immune system to effectively police tuberculosis (TB) of the lungs and prevent it from turning into an active and deadly infection, according to a new study led by researchers at Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh School of Medicine. Their findings appear today in the online version of the Journal of Clinical Investigation. http://medicalxpress.com/news/2013-01-team-molecule-polices-tb-lung.html Diseases, Conditions, Syndromes Wed, 02 Jan 2013 12:00:01 EST news276343612 A study led by The University of Manchester has demonstrated that new technology that can analyse millions of gene sequences in a matter of seconds is an effective way to quickly and accurately identify diseases in skeletons. http://medicalxpress.com/news/2012-10-technology-life-diseases-bones.html Medical research Mon, 22 Oct 2012 15:00:18 EST news270136349 US health authorities on Thursday urged a 12-week drug regimen for people with latent tuberculosis as an effective alternative to the current nine-month regimen which many people do not finish. http://medicalxpress.com/news/2011-12-urges-shorter-treatment-tb.html Diseases, Conditions, Syndromes Thu, 08 Dec 2011 13:09:46 EST news242572175 Statens Serum Institut and Aeras today announce the initiation of the first Phase I clinical trial of a new candidate TB vaccine designed to protect people latently infected with TB from developing active TB disease. The trial is being conducted by the South African Tuberculosis Vaccine Initiative (SATVI) at its field site in Worcester, in the Western Cape province of South Africa.
