Latest Acid fast bacilli Stories
Study led by Weill Cornell Medical College and published in the journal PNAS.
Mycobacterium tuberculosis (Mtb) possesses extraordinary survival ability by masking itself from the host immune system and persisting for decades inside the host.
The factors instrumental in triggering latent tuberculosis (TB) infection to progress into active disease have long remained elusive to researchers.
Researchers at Albert Einstein College of Medicine of Yeshiva University have found two novel ways of killing the bacteria that cause tuberculosis (TB), a disease responsible for an estimated two million deaths each year.
Badger culling is unlikely to be a cost-effective way of helping control cattle TB in Britain, according to research published today in PLoS ONE.
Researchers at the MUHC and their international colleagues have identified the first genetic resistance factor against tuberculosis infection.
For thousands of years an undesirable and persistent companion has been traveling with man wherever he goes. Mycobacterium leprae, the bacterium that causes leprosy, has only one known natural host â€“ mankind.
A bacterium possibly linked to Crohn's disease could be lurking in wild animals. According to research published in the open access journal BMC Microbiology, Mycobacterium avium subspecies paratuberculosis (Map), can be transmitted between wildlife and domestic ruminants, supporting the theory of wildlife reservoirs of infection.
Researchers at Iowa State University have identified an enzyme that helps make tuberculosis resistant to a human's natural defense system.
A British government scientist is believed to have contracted bovine tuberculosis from an infected badger, a government official said. Thirty other staff members employed by the government's Food and Environment Research Agency in Woodchester, England, near Stroud, are also being tested for the often deadly infectious disease, said Alison Wilson, FERA's head of executive support. This is the first time a suspected case of mycobacterium bovis has jumped the species barrier and caused human...
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...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
