Latest Corynebacterineae Stories
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.
Technology Also Offers Potential for Human TB Tests, as Well as Animal and Human TB and Other Vaccines PALMERSTON NORTH, New Zealand, April 2, 2014 /PRNewswire/ -- PolyBatics, Inc.,
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.
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, while transmission between cattle herds accounts for the remainder.
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.
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.
Mycobacterium tuberculosis, the bacterium that causes tuberculosis may have an Achilles’ heel: It needs a particular enzyme to survive.
Scientists are using thousand-year-old remains to help reconstruct the genomes of the medieval leprosy pathogen and uncover the history of the disease.
During the 1930s, dedicated sanitaria and invasive surgery were commonly prescribed for those with the infection - usually caused by Mycobacterium tuberculosis, which the editors describe as "the most successful human pathogen of all time."
In a paper published today in the journal PLOS ONE, a research team headed by Dr.
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 Âµm 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...
