Latest Acid fast bacilli Stories
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.
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.
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.
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.
According to the World Health Organization (WHO), one-third of the world's population is currently infected with tuberculosis bacteria.
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.
It's estimated that nearly one-third of the world's population—more than two billion people—are infected with Mycobacterium tuberculosis.
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...
