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. Table I provides the popular names, history, stigma, description of the disease, clinical features, classification and the types of disease manifestations, who are affected, Signs and Symptoms, Clinical examination, treatment regimens, reactions, relapses, immunity, infectiousness, risk groups,...

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....

MANHATTAN, KAN. -- 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. "It" is Mycobacterium tuberculosis. A Kansas State University chemistry professor is seeking to stem the tide in the war against TB. According to the WHO, no new antituberculosis drugs have been marketed during the last...

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...

As children acquire infection with Mycobacterium tuberculosis from adults in their environment, the epidemiology of childhood tuberculosis (TB) follows that in adults. While global burden of childhood tuberculosis is unclear, in developing countries the annual risk of tuberculosis infection in children is 2- 5 per cent. Nearly 8-20 per cent of the deaths caused by tuberculosis occur in children. It has been suggested that BCG vaccination is responsible for decrease in the occurrence of...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
