Cellestis has launched the TB Operation Support Solution (TBoss), a comprehensive service to help support U.S. public health officials in the management of TB contact investigations through the use of QuantiFERON®-TB Gold (QFT®), an interferon gamma release assay (IGRA) approved by the FDA as an in vitro diagnostic aid for the detection of TB infection. Valencia, CA (PRWEB) September 14, 2011 Tuberculosis (TB) is a highly contagious and potentially fatal disease affecting more than...

Published in Journal of Applied Microbiology Researchers have discovered a faster, cheaper method for the diagnosis of tuberculosis (TB). A major barrier in TB prevention, especially in developing countries, is that diagnosis is slow and costly. Dr Olivier Braissant and his colleagues have developed a method which could potentially decrease the time taken to make a diagnosis. Their method is also cheaper than the current fastest methods. This research has been published today in the Society...

MELBOURNE, Australia, July 25, 2011 /PRNewswire/ -- A new policy recommendation released on 20 July by the World Health Organization (WHO) warns against the use of serological (blood) tests to diagnose active tuberculosis (TB). Serological tests measure antibodies to TB in serum and are different to QuantiFERON, which measures responses of white blood cells to TB specific proteins. Active tuberculosis occurs when the TB organism has overcome the body's immune defences and proliferates...

Press release from PLoS Medicine Two studies by a team of researchers led by Luis E. Cuevas and Mohammed Yassin from the Liverpool School of Tropical Medicine and jointly coordinated with Andrew Ramsay at WHO-TDR Special Programme for Research and Training in Tropical Diseases are published in this week's PLoS Medicine. The studies have important implications for the ways in which diagnosis for the endemic infectious disease, tuberculosis (TB), can be done in poor countries. One study...

(Ivanhoe Newswire) "“ Two new methods to diagnosing tuberculosis, an endemic infectious disease, can be used in poor countries. One study suggests that less sputum tests collected the same day of consultation are needed and the other suggests that a faster laboratory test can be used while maintaining the same level of accuracy for diagnosis. Both studies show that alternative, less labor-intensive tests that are more convenient for patients could be effectively used in poorer...

Current UK procedures to screen new immigrants for tuberculosis (TB) fail to detect more than 70 per cent of cases of latent infection, according to a new study published in The Lancet Infectious Diseases. TB is caused by a bacterial infection which is normally asymptomatic, but around one in 10 infections leads to active disease, which attacks the lungs and kills around half of people affected. Today's research showed that better selection of which immigrants to screen with new blood tests...

The Centers for Disease Control and Prevention (CDC) fell short of its goal of eradicating tuberculosis (TB) by the year 2010, health officials told AFP recently, despite the number of reported cases being at an all-time low. The CDC publication Morbidity and Mortality Weekly Report, found 11,181 known cases of the airborne and highly contagious disease in the US last year, a 3.9 percent drop from 2009. Tuberculosis is caused by the mycobacterium tuberculosis bacterium and usually attacks...

Scientists have discovered a protein secreted by tuberculosis (TB) bacteria that could be a promising new vaccine candidate, they report in the March 18 issue of Proceedings of the National Academy of Sciences. The protein could also be used to improve diagnosis of TB. TB is caused by the bacterium Mycobacterium tuberculosis (MTB), which infects the lungs and spreads through the air as a result of coughing. There are 9 million new cases of TB each year, killing 4,700 people a day worldwide....

Identifying tuberculosis patients in Africa using passive methods is leaving many cases undiagnosed, according to researchers from the Netherlands, Kenya and the United States, who studied case detection methods in HIV-prone western Kenya. Tuberculosis (TB) occurs commonly in men and women with HIV, but in these patients TB can be more difficult to detect. The findings were published online ahead of the print edition of the American Thoracic Society's American Journal of Respiratory and...
