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...

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...

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...

St. Petersburg, Russia "“ 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. In this study, a team of scientists led by Dr....

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. This research, scheduled to be published in the Aug. 30 issue of the Proceedings of the National Academy of Sciences, also provides the foundation for a better...

MONTREAL - 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. The new study published in the Proceedings of the National Academy of Science (PNAS) this week provides a new view of the mechanisms underlying the development of tuberculosis and may contribute to public health efforts aimed at containing the disease. "About one-third of the world's population is infected by...

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. Overexpression of either Pkn protein results in a cell shape defect. Dr. Husson is confident that "these findings describe a...

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...
