redOrbit Staff & Wire Reports - Your Universe Online One of the deadliest infectious diseases in the world may have been carried to the Americans by seals and sea lions, not European explorers as previously believed, claims a new study published online Wednesday in the journal Nature. Tuberculosis is responsible for killing as many as two million people each year, and according to researchers from the Arizona State University and an international team of experts, scientists have...

Mycobacterium tuberculosis is a major cause of death worldwide, and a formidable foe. Most healthy people can defend themselves against tuberculosis, but they need all parts of their immune system to work together. A study published on January 2nd in PLOS Pathogens reveals how a special class of immune cells called "invariant natural killer T cells" make their contribution to this concerted effort. "We were interested in identifying the mechanisms that different types of T cells use to...

Mycobacterium tuberculosis, the bacterium that causes tuberculosis may have an Achilles’ heel: It needs a particular enzyme to survive. Inhibiting that enzyme’s function, researchers have shown, will kill the bacteria, pointing toward a design strategy for new TB drugs. To stay ahead in the race against drug-resistant infections, scientists constantly search for and exploit vulnerabilities in deadly bacteria. Now, researchers from Brown and the Massachusetts Institute of Technology...

Origins Of Tuberculosis Traced To Humans 70,000 Years Ago

redOrbit Staff & Wire Reports - Your Universe Online Despite previous research suggesting that tuberculosis originated in animals just 10,000 years ago, scientists have now traced the origin of the illness back to humans living in Africa at least 70,000 years ago. According to BBC News science reporter Julie Gould, an international team of researchers “combined geographic and genetic data from 259 strains of TB to reconstruct its evolutionary history and compare it to the origins...

Adapting tools of evolutionary biology to study the epidemiology of outbreaks reveals 39 new genes implicated in drug resistance For years, physicians around the world have watched as strain after strain of the deadly bacteria Mycobacterium tuberculosis evolves resistance to drugs. Over the last few decades researchers have used the tools of molecular biology to identify a handful of individual mutations that allow TB to withstand many of the key therapeutics that doctors use to treat...

A new form of genetic testing of the bacteria that causes tuberculosis can provide better information on TB transmission and also trace TB outbreaks more accurately than the current standard test, according to a study from Germany published in this week's PLOS Medicine. A team of researchers led by Stefan Niemann from Forschungszentrum Borstel, Molecular Mycobacteriology, compared the results of the two types of tests on 86 M. tuberculosis isolates from a TB outbreak in the German states...

Provocative NEJM essay calls for redoubling of efforts Each year, nearly 2 million people die from tuberculosis — a treatable disease that has been brought under control in the United States, but continues to ravage other parts of the world. This health inequity should prompt a complete rethinking of the way tuberculosis is fought on a global level, argue Salmaan Keshavjee, MD, PhD, and Paul Farmer, MD, PhD, from Brigham and Women's Hospital (BWH). Their argument appears in an essay...

Scientists of the Antwerp Institute of Tropical Medicine have breathed new life into a forgotten technique and so succeeded in detecting resistant tuberculosis in circumstances where so far this was hardly feasible. Tuberculosis bacilli that have become resistant against our major antibiotics are a serious threat to world health. If we do not take efficient and fast action, 'multiresistant tuberculosis' may become a worldwide epidemic, wiping out all medical achievements of the last...

Mycobacterium tuberculosis (MTB) is a pathogenic bacterial species in the genus Mycobacterium and the causative agent of most cases of tuberculosis. Robert Koch first discovered it in 1882 and that it had an unusual, waxy coating on the cell surface which makes them impossible to Gram stain. M. tuberculosis is highly aerobic and requires high levels of oxygen. It generally infects the respiratory system of mammals. Tuberculin skin test, acid-fast stain, and chest radiographs are the most...
