Latest Acid fast bacilli Stories
Mycobacterium tuberculosis is arguably the world's most successful infectious agent because it knows how to avoid elimination by slowing its own growth to a crawl.
Researchers claim to have discovered the earliest evidence of leprosy in a 4,000-year-old skeleton from India.
Scientists in Ohio are reporting a long-awaited advance toward making the workplace safer for more than one million machinists in the United States who may be exposed to disease-causing bacteria in contaminated metalworking fluids.
British medical scientists say the discovery of a large number of slow-growing Mycobacterium tuberculosis bacteria might lead to new anti-TB drugs. Until now it was thought that M. tuberculosis bacteria in the lungs of TB patients were rapidly multiplying.
Tiny viruses are engineered to inject TB bacteria with green-glowing protein for a fast, on-site diagnosis.
A new species of bacterium that causes leprosy has been identified through intensive genetic analysis of a pair of lethal infections, a research team reports in the December issue of the American Journal of Clinical Pathology.
Presentations made at scientific conferences this week announced recent successes in utilizing Biolog technology to advance our understanding of important pathogenic bacteria.
Scientists have discovered that a bone infection is caused by a newly described species of bacteria that is related to the tuberculosis pathogen.
The skeleton of a man discovered in a shallow grave on what is now a college campus in England could belong to one of Britain's earliest victims of tuberculosis. Radiocarbon dating suggests the man died in the fourth century, around A.D. 302, when Romans ruled the region.
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 dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
