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...

UCLA scientists engineered a new tuberculosis (TB) vaccine specifically designed for HIV-positive people that was shown to be safer and more potent than the current TB vaccine in preclinical trials. A more effective TB vaccine may help curtail the global spread of the disease, especially in HIV-positive people, for whom tuberculosis is the leading cause of death worldwide. "The AIDS and tuberculosis epidemics are now so intertwined in many parts of the world that we can't win the fight...

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 Anonymous Professor Brigitte Gicquel is head of the Mycobacterial Genetics unit at the Pasteur Institute in Paris, France. After completing her undergraduate and doctoral studies at the University of Paris VII, she joined the Pasteur Institute in 1973 and has spent much of her scientific career concentrating on the genetics of Mycobacterium tuberculosis. Gicquel coordinated both the European Commission's efforts to find a vaccine more efficient than bacille Calmette- Guerin (BCG) 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...

Ronald Reagan; an investigation was conducted to determine a screening strategy for 1,172 civilian passengers who were aboard during a temporary guest rider program. Sailors were...

By DeRiemer, Kathryn De Jong, Bouke C The estimated 9.2 million new cases of tuberculosis (TB) and 1.7 million annual deaths from TB during 2006 are a bleak reminder that new, creative strategies are needed to prevent and controlTB worldwide (1). For the past 15 years, molecular epidemiologic techniques have been used to identify clusters of TB cases whose isolates have identicalDNAfingerprints or genotypes, indicating recent transmission of Mycobacterium tuberculosis (2). In this issue of...

U.S.-led medical scientists say they have found the source of drug-tolerant tuberculosis, as well as the bacteria causing TB relapses. University of Pittsburgh-led researchers discovered the primary bacteria behind tuberculosis can grow on surfaces and that drug-tolerant strains flourish in such bacterial communities. The finding, the scientists said, suggests a possible reason why human TB requires months of intensive antibiotic treatment and indicates a potential cause of the relapses...

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 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...
