Presentations made at scientific conferences this week announced recent successes in utilizing Biolog technology to advance our understanding of important pathogenic bacteria. At the Texas and South Central ASM meeting in Austin, Texas, Professor Lacy Daniels' group from Texas A & M University presented their most recent findings using Biolog Phenotype MicroArray (PM) Technology to study species of the genus Mycobacterium. These bacteria are challenging agents of human and animal...

Scientists have discovered that a bone infection is caused by a newly described species of bacteria that is related to the tuberculosis pathogen. The discovery may help improve the diagnosis and treatment of similar infections, according to an article published in the October issue of the International Journal of Systematic and Evolutionary Microbiology.Some rare genetic diseases can make patients susceptible to infections with Mycobacterium species, the bacteria that amongst other diseases,...

U.S. researchers have determined that Mycobacterium tuberculosis has learned through evolution to coat itself with a sugar called mannose. This sugar makes the bacterium attractive to cells in the lungs that are looking to clean up and discard unwanted sugar in the body. Those lung cells absorb the TB bacteria, giving the infecting bacteria a place to live for the long term, Ohio State University researchers said. "The bug sugarcoats itself and creates this magical interaction that allows...

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. He was interred in a shallow scoop in a flexed position, on his right side. The man, aged 26 to 35 years old, suffered from iron deficiency anemia during childhood and at 5-foot, 4-inches, was shorter than average for...

By Jarzembowski, Jason A Young, Michael B * Context.-Nontuberculous mycobacteria include numerous acid- fast bacilli species, many of which have only recently been recognized as pathogenic. The diagnosis of mycobacterial disease is based on a combination of clinical features, microbiologic data, radiographic findings, and histopathologic studies. Objective.-To provide an overview of the clinical and pathologic aspects of nontuberculous mycobacteria infection, including diagnostic laboratory...

Britain's environmental secretary has confirmed the government will not be issuing licenses to cull cattle tuberculosis (TB). Hilary Benn made the remarks in a Commons statement, and acknowledged that although a broad-based cull might improve the situation, it could also worsen the problem. The details about the decision were made public in a BBC News report, which said Britain's National Farmers' Union (NFU) is seeking legal advice about the situation. The disease affected approximately...

A tuberculosis outbreak in Welsh cattle as resulted in a "targeted cull" of badgers to eradicate the disease. Details and location of the cull have not been announced. According to rural affairs minister Elin Jones, the Welsh Assembly Government's plan includes a one-off test of all cattle and a review of the compensation system Wales' chief veterinary officer said bovine TB was out of control and the current policy was not working. Incidents of TB in cattle have increased dramatically and...

OXFORD -- Britain is set to cull badgers in a bid to tackle bovine tuberculosis despite opposition from wildlife groups, Tim Bennett, president of the National Farmers' Union, said on Wednesday. "That (a badger cull) is not a debate. Frankly this is going to happen," Bennett told reporters at a news conference held at the annual Oxford Farming Conference. Last month the British government announced it was holding a consultation about whether to cull badgers in a bid to control the spread...

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 µm 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...
