Latest Mycobacterium Stories
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).
U.S.-led medical scientists say they have found the source of drug-tolerant tuberculosis, as well as the bacteria causing TB relapses.
By Veeser, Peggy Ingram Smith, Phillip Karl; Handy, Barry; Martin, Sharon R Abstract. Detecting and managing Mycobacterium tuberculosis (TB) infection in a health-science center population is a clinical dilemma.
By Hussain, Tahziba A quick glance at this review article provides an insight into the common and different features of M. leprae and M. tuberculosis and the diseases caused by these organisms.
Genghis Khan and his troops may have unwittingly used more than just brute military force to conquer entire nations and to establish the infamous Mongolian empire. A report in the October issue of Genome Research suggests that Genghis Khan's invasions spanning the continent of Asia during the 13th century may have been a primary vehicle for the dissemination of one of the world's most deadly diseases: tuberculosis.
It has been identified by the World Health Organization as the most dangerous infectious disease, causing more deaths -- more than 2 million a year -- than any other single infection. Approximately one-third of the world's population is already infected.
Researchers at the University of Minnesota, working in collaboration with scientists at the USDA, have used genomic information to develop tests that can rapidly detect and differentiate the bacteria that causes Johne's disease, a chronic wasting disease found in cattle and other ruminant animals such as sheep, goats and deer.
Scientists at the MUHC have discovered a gene that controls the speed at which patients develop tuberculosis--the first time such a gene has been discovered for this disease.
Dr. Robert Husson and colleagues have found two serine threonine kinase genes (pknA and pknB) that regulate cell shape, and possibly cell division, in the bacterial pathogen, Mycobacterium tuberculosis. The researchers identified three in vivo substrates of PknA and PknB, one of which (Wag31) is an important factor in controlling bacterial cell division and cell shape.
As children acquire infection with Mycobacterium tuberculosis from adults in their environment, the epidemiology of childhood tuberculosis (TB) follows that in adults.
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...
