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...

Findings could lead to more effective treatment for global disease A new study led by Harvard School of Public (HSPH) researchers provides a novel explanation as to why some tuberculosis cells are inherently more difficult to treat with antibiotics. The discovery, which showed that the ways mycobacteria cells divide and grow determine their susceptibility to treatment with drugs, could lead to new avenues of drug development that better target tuberculosis cells. The study appears...

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...

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...

Corynebacterium diphtheriae is a pathogenic bacterium that causes diphtheria. It was discovered in 1884. There are four subspecies C. diphtheriae mitis, C. diphtheriae intermedius, C. diphtheriae gravis, and C. diphtheriae belfanti. They all are a little bit different in their colonial morphology and biochemical properties such as the ability to metabolize certain nutrients. The diphtheria toxin gene is encoded by a bacteriophage which is found in toxigenic strain. A gram stain is...
