In a paper published today in the journal PLOS ONE, a research team headed by Dr. Paul Wheeler from the Animal Health and Veterinary Laboratories Agency (AHVLA, Weybridge, UK) reported breakthrough progress in understanding the metabolic and phenotypic properties of the bacterium Mycobacterium tuberculosis and its close relative, Mycobacterium bovis. Hayward, CA (PRWEB) January 10, 2013 In a paper published today in the journal PLOS ONE, a research team headed by Dr. Paul Wheeler from the...

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...

(Ivanhoe Newswire) -- In 2010 the World Health Organization (WHO) estimated there were 290,000 cases of multi-drug resistant tuberculosis globally. Now a new medication attempts to slash those numbers. Delamanid, a nitro-dihydro-imidazooxazole derivative, is a new medication that inhibits mycolic acid synthesis (long fatty acids found in the cell walls of the mycolata taxon) and has shown potent in vitro (half living-in a Petri dish) and in vivo (living in the body) activity against drug...

According to the World Health Organization (WHO), one-third of the world's population is currently infected with tuberculosis bacteria. The bacteria is incredibly resistant to treatment, and despite its prevalence, very little is known about why it is so stress tolerant. But, researchers at the University of Pittsburgh have been developing a new way of culturing tuberculosis bacteria, which could lead to new insights and treatments. "This is a significant step forward in TB research," said...

A University of Adelaide scientist says much more could be done to predict the likelihood and spread of serious disease - such as tuberculosis (TB) or foot-and-mouth disease - in Australian wildlife and commercial stock. Professor Corey Bradshaw and colleagues have evaluated freely available software tools that provide a realistic prediction of the spread of disease among animals. They used a combination of models to look at the possible spread of TB among feral water buffalo in the...

It's estimated that nearly one-third of the world's population–more than two billion people–are infected with Mycobacterium tuberculosis. According to the World Health Organization, 5 to 10 percent of infected people eventually develop active tuberculosis and can transmit the bacterium to others. Almost two million die from the disease each year. But the current treatment regimen for the disease is long and arduous, making patient compliance difficult. As a result, some strains of...

The bacterium that causes tuberculosis has a unique molecule on its outer cell surface that blocks a key part of the body´s defense. New research suggests this represents a novel mechanism in the microbe´s evolving efforts to remain hidden from the human immune system. Researchers found that the TB bacterium has a molecule on its outer surface called lipomannan that can stop production of an important protein in the body´s immune cells that helps contain TB infection and...

TB Vaccine Shows Promising Results In Lab Tests

  Scientists at the Albert Einstein College of Medicine reported on Sunday that a vaccine they developed for tuberculosis had shown promising results during early laboratory testing in mice. Professor William Jacobs and colleagues, who published their findings in the journal Nature Medicine on Sunday, worked with Mycobacterium smegmatis, a species similar to tuberculosis that is lethal in mice but harmless to humans. "The researchers created a version of M. smegmatis lacking a...

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...

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...

Mycobacterium smegmatis is 3.0 to 5.0 µm long with a bacillus shape, an acid-fast bacterial species in the phylum Actinobacteria. It can be stained by Ziehl-Neelsen method and the auramine-rhodamine fluorescent method. It was first reported in 1884. Alvarez and Tavel found organisms similar to Lustgarten, who first discovered Mycobacterium. This organism was later named M. smegmatis. It is considered a non-pathogenic microorganism although, in rare cases, it can cause disease. M....

Mycobacterium leprae, mostly found in warm tropical countries, is a bacterium that causes leprosy (Hansen's disease). It is an intracellular, pleomorphic, acid-fast bacterium. M. leprae is an aerobic rod-shaped surrounded by the characteristic waxy coating unique to mycobacteria tuberculosis. Due to its thick waxy coating, M. leprae stains with a carbol fuscin rather than with the traditional Gram stain. Gerhard Armauer Hansen first discovered it in 1873. It was the first bacterium to be...

Mycobacterium bovis is a slow-growing, aerobic bacterium and the causative agent of tuberculosis in cattle. Similar to M. tuberculosis, M. bovis can jump the species barrier and cause tuberculosis in humans. It is estimated that M. bovis was responsible for more losses among farm animals than all other diseases combined in the first half of the 20th century. Infection happens after bacterium is ingested. It is generally transmitted to humans via infected milk. Actual human infections are...
