Mycobacteria Metabolism Discovery Could Pave Way For New Tuberculosis Drugs
2014-07-23 03:23:02

University of Otago The mystery of why mycobacteria—a family that includes the microbe that causes TB—are extraordinarily hardy organisms is being unraveled by University of Otago, New Zealand, research that offers new hope for developing a revolutionary class of antibiotics to tackle TB. In collaboration with researchers in the US and Germany, Otago microbiologists have teased out the mechanisms by which the aerobic soil microbe Mycobacterium smegmatis is able to persist for...

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...

Badger Social Networks And The Spread Of Bovine Tuberculosis
2013-10-22 04:31:26

April Flowers for redOrbit.com - Your Universe Online The social lives of badgers are related to their risk of infection with bovine tuberculosis (TB), according to a new study from the University of Exeter and the AHVLA's National Wildlife Management Center. "In wild animals, just as in humans, social networks are very important for disease transmission," said Robbie McDonald of the University of Exeter. "When management changes stable networks, the results for disease control are...

Badgers Responsible For Half Of Tuberculosis Found In Cattle
2013-10-11 13:47:01

Lee Rannals for redOrbit.com - Your Universe Online A new study published in the journal PLoS Currents: Outbreaks suggests that badgers are responsible for a large number of tuberculosis (TB) cases in cattle in certain areas. Researchers estimate that badgers ultimately account for 52 percent of cattle TB in areas where prevalence in cattle is high. However, only around six percent of infected cattle catch TB from badgers; the remaining number of cases is a result of transmission of the...

Your Aquarium May Harbor Bacterial Organism Mycobacterium Marinum
2013-10-07 04:16:24

redOrbit Staff & Wire Reports - Your Universe Online Mycobacterium marinum infection, a skin condition associated with exposure to contaminated water in home aquariums, is under-diagnosed, according to new research presented Saturday at the Infectious Diseases Society of America's annual meeting in San Francisco (IDWeek 2013). The study, which was sponsored by the Henry Ford Hospital in Detroit, Michigan, reported that the infection is difficult to diagnose and treat because skin...

Tsukuba, Japan, Oct 3, 2013 - (ACN Newswire) - More than a century after the identification of organisms that cause tuberculosis (TB), this disease remains a global public health challenge. According to World Health Organization estimates, there were 8.7 million new cases in 2011 and 1.4 million deaths. Most new cases occur in developing countries that lack the facilities and trained personnel required for early detection of TB.In a new study, published in the journal Science and Technology...

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
2013-09-03 05:21:01

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...

Uncovering The History Of Medieval Leprosy With Genomics
2013-06-14 14:24:28

Lee Rannals for redOrbit.com — Your Universe Online Scientists are using thousand-year-old remains to help reconstruct the genomes of the medieval leprosy pathogen and uncover the history of the disease. Researchers wrote in Science magazine about how they used the remains of skeletons to successfully reconstruct a dozen medieval and modern genomes of the leprosy-causing bacteria Mycobacterium leprae. They were able to create a genome from archaeological finds for the first time...

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...
