Latest Corynebacterineae Stories
The bacterium that causes tuberculosis has a unique molecule on its outer cell surface that blocks a key part of the body’s defense.
A potential vaccine against tuberculosis (TB) has been found to completely eliminate TB bacteria from infected tissues in some mice.
An experimental vaccine composed of a genetically modified bacterium closely related to the bacterium that causes tuberculosis (TB) has been found to protect mice against TB infection.
A potential vaccine against tuberculosis has been found to completely eliminate tuberculosis bacteria from infected tissues in some mice.
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.
Researchers have discovered a faster, cheaper method for the diagnosis of tuberculosis (TB).
Are you genetically predisposed to tuberculosis?
Localized badger culling in response to bovine tuberculosis (TB) outbreaks increases the risk of infection in nearby herds, according to a new analysis.
Scientists have identified a source for some of the unexplained Leprosy cases that appear in the southern US - the nine-banded armadillo.
A new study published in the New England Journal of Medicine reveals a new strain of leprosy has surfaced in the Southern United States.
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...
